LightPath – Flexible Beam Expanders Beam expanders are used in a variety of optical applications in the industrial, medical, defense and instrumentation markets including metrology, laser delivery systems, LIDAR and beam conversion. Unlike conventional beam expanders, LightPath’s flexible beam expanders incorporate a single-mode or polarization-maintaining fiber between the input and output lenses. By using the fiber, the input and output beams can be positioned independently from one another, allowing the freedom to mount the beam expander in tight spaces that normally would require a series of free space optics. Because the fiber is used between the input and output lenses, the output beam diameter will remain steady - even when there are fluctuations to the input beam diameter. With traditional beam expanders, the output beam diameter changes whenever there

The fiber also acts as a spatial filter for the input beam, removing unwanted high-frequency optical noise and producing a clean gaussian intensity distribution. This is perfect for application in optics where size, angular flexibility and improved beam quality are important.”

Spectral Hyper Adapter The new SHA-1 Hyper Adapter is designed to interface with the Ocean Optics HR-4000 spectrometer. Making a conventional grating spectrometer small usually means limiting the spectral resolution – not any more! The Hyper Adapter (model SHA-1) to extend the spectral resolution of the Ocean Optics HR4000 spectrometer by a factor of up to ten. This exciting development allows the user to see features that would be otherwise unresolved while retaining the advantages of a small package. The HR4000 range-toresolution ratio of 1,500:1 is extended to 15,000:1. That means that a 5 pm resolution is achieved when used with a spectrometer
ing the SHA-1 in series with the HR4000 spectrometer. It is as easy as that. The optical input and output to the SHA-1 are 50-micron multi-mode fiber optic cables, making connection of the modular unit extremely simple. Commands are transmitted via the USB port and data acquisition is synchronized with the HR4000.

SmartTable guarantees a stable surface The ST Series SmartTable incorporates Newport’s patent-pending iQ Technology to monitor, report, and adjust table damping performance over wide frequency bands. This provides a dramatically quieter surface, resulting in faster settling times, high-quality imaging and long-term stability. Over the years, many attempts have been made to reduce table top resonance vibration by damping. So far, the best results have been achieved with vibration absorbers, or tuned dampers, such as the ones used in Newport’s RS Series of tables. Each tuned damper is optimized for a specific vibration frequency and mode. The new ST Series SmartTable uses electromechanical vibration dampers that dampen all natural vibration modes in a given range, without creating additional resonance at lower frequencies. If the table conditions change, the dampers can be quickly retuned for optimum damping. Q is the term used to describe the maximum amplification of a structure at resonance. The lower the Q, the more the structural rigidity is maintained. Newport’s SmartTable provides a stable work surface by using active sensing and correction technology to update the structure’s damping properties at 10 kHz to eliminate or minimize disturbances. In addition to iQ technology, the SmartTable controller’s analog outputs can also provide

system feedback for monitoring, triggering or halting processes. This dramatically improves throughput and yield, and is particularly effective for the manufacturing of sensitive optics, precise laser micro-machining, micro-electronics processing, or device testing. The new SmartTable enables tabletop vibration monitoring through built-in vibration sensors, which provide real-time feedback on the vibration mode of the table. The ST Series tables are USB2 compatible. Software is also available to further fine-tune and calibrate the table, and can be used to gather vibration data.

Pulsed Laser Diodes with 210 W A world premier was presented at the Photonics West Exhibition in the USA. For their 905D3J08 series, Laser Components Canada manufactures pulsed laser diodes with a peak power of more than 210 W at 905 nm. The basis is the already proven nanostack laser technology, which includes multiple epitaxial integrated emitters with a total aperture of 200 µm x 10 µm. A peak output power of at least 75 W can be obtained with “single emitters” at a pulse length of 100 ns. More than 140 W respectively, 210 W is achievable with stacked devices. The emitting area for the double stack thereby merely amounts to 200 µm x 125 µm. fFor the triple stack it is 200 µm x 250 µm. The high peak power coupled with the small emitting area results in optimal power intensity. As a result, these pulsed laser diodes open completely new perspectives for applications such as ceilometers, altimeters, LIDAR, or telemetry at great distances.
These new 905 nm pulsed laser diodes are supplied in a TO-18, 5.6 mm, 9 mm and 8 – 32 coax package or as a chip on a ceramic carrier.

A new signal axis amplifier module The new single axis piezo amplifier NV 40/1CLE is designed for closed loop control for low voltage piezo electrical actuators equipped with strain gauge or capacitive feed back sensors. These elements are marked with additional “E” at the end of the part number. The NV 40/1CLE is able to read all actuator information stored on the ID chip inside the cable box of the actuator. All calibration data is now stored in the ID chip of the actuating system. This enables our customers to exchange actuators without having to re-calibrate their systems. This
makes your system independent from an extensive recalibration procedure. The amplifier can be controlled by analog signal on the modulation input, by computer interface (RS 232 line) or by manual operation – through a potentiometer. The 6-digit display on the front panels reads the value of signal in V or the range of motion in microns. An integrated memory function gives the customer the opportunity to adjust a memorized position without any delay. The small size of the amplifier unit is recommended for labs and industrial applications. The NV 40/1CLE should be your first choice for all single axis nano-positioning stages when you need high speed, accuracy, repeatability and reliability.

These fringe patterns are projected onto the sensitive, high density CCD-arrays, and allow an unambiguous, “single shot” determination of the wavelength. The fringe patterns also contain information on the coherence of the laser beam, and interpolation routines are used to determine

A range of wavelength measurement instruments based on a solid-state etalon design has long set the mark in terms of overall stability, spectral resolution as well as read out speed. Whereas previous designs for wavelength meters (WLMs) relied upon a scanning-arm Michelson interferometer [1], todays stateof-the-art-technologie is based on wedgedshaped etalons (a.k.a. Fizeau interferometers) to essentially translate the traditional longitudinal length scan into a transverse composite fringe pattern. The acquisition rate is only limited by the sensitivity and read out speed of the CCD. Even pulse laser systems can be measured, given that the linewidth does not exceed 60 GHz (the limit for which fringes can still be identified). Actual high precision WLMs consist of multiple etalon-CCD pairs, each etalon having

the linewidth for (quasi-)cw or the spectral shape for pulsed laser light. Additionally, one can instantly recognize side modes on the laser intensity (Fig. 2). As the etalons are shaped from materials whose optical and thermal properties have been thoroughly characterized, and are contained within a thermally stabilized environment, a single known wavelength suffices for calibration. The exclusion of any moving parts in the instrument translates into very low maintenance, and typical instruments have even been proven even under extreme conditions, such as free-fall conditions [2]. Once calibrated, these WLMs remain true for extended periods of time (months) and achieve wavelength resolution down to the 1 MHz level (Fig. 3). Given sufficient measurement intensity, data acquisition rates of up to 500 Hz are possible and the system can then be used for real-time wavelength stabilization (e.g. to counteract acoustic frequency noise). This acquisition speed can alternatively be used to determine and control the difference between two laser wavelengths. When available laser power is limited, increasing the exposure time for the measurement reduces intensity requirements down to only 10 nW. (Fig. 4) The accessible wavelength range of solid-state WLMs is limited by the spectral sensitivity of the detectors used. The substitution of the silicon-based CCDs with materials with a higher efficiency in the UV extends the range down to 220 nm. Until recently, the range in the IR was limited to 2250 nm, but new PbSe CCD-arrays extend this out to 5000 nm (or 5 µm), with no limitations to the use for pulsed laser systems (see above).

UV light sources in semiconductor manufacturing The trend toward smaller feature sizes in microlithography requires not only a shift to shorter wavelength, but also the use of special techniques, so called Resolution Enhancement Techniques. A very successful technique is the application of Phase Shift Masks (PSM) in addition to the common Amplitude Mask. The PSM introduces a complex amplitude information and a phase shift in parts of the wavelength in use. In this way the critical dimension of the lithographic process can be improved because the complex amplitude has also negative values which provides a much better definition for the intensity value zero. However, one difficult issue is the reliable measurement of phase shifts created by the PSM in the deep UV. This is due to the lack of suitable and simple interferometric devices in the deep UV. In this application report a deep UV interferometer based on phase gratings is presented. Principles of PSM measurement By combining two Ronchi-phase gratings, placed in the imaging light path of a microscope working in transmission mode, it is possible to generate two laterally sheared wave fronts which carry the phase information of the object of interest. The introduced shear depends on the distance between the two Ronchi-phase gratings. A five-phase algorithm can be used to analyze the fringe pattern generated as a function of the lateral shift between the two gratings. Information about the phase shift of the object is thus obtained. To introduce large shears, a complex coherence has to be prepared. This is done by the use of a structured light source, a technique which reduces unwanted interferences and allows for a high contrast ratio (>0.8) combined with minimum light loss. Under these conditions, the phase step introduced by a PSM structure can be measured with a high degree of accuracy. Design Considerations of the Interferometer and Light Source The stability of the interferometer is critical for measurement accuracy, especially if short wavelengths are to be used. For instance a phase shift between the interfering waves resulting from a 1 nm feature leads to a change in intensity of only 1.65% at 193 nm. In or-

der to map features with sub-nanometer dimensions, changes in intensity on the order of 1% must be accurately measurable. The stability of the laser source is the overriding design feature of a sufficiently accurate interferometer. When measuring the phase steps of the mask, sub-nanometer accuracy is necessary in a state-of-the-art lithographic process. Without an extremely stable light source this is not possible. Low shot-to-shot noise and high long-term stability (over a period of hours) in both continuous and burst modes are required for high performance interferometry at 193 nm. Another parameter which must be optimized is the beam profile. An asymmetric beam profile results in poorly defined coherence in the object plane of the interference microscope. A homogeneous beam profile is a key to data that can be interpreted meaningfully. Furthermore, the stochastic noise in the CCD detector can be quite significant. Only with a
high repetition rate (up to 1000 Hz) excimer laser can sufficient averaging be carried out to obtain acceptable signal-to-noise ratios in the phase measurements. Wind currents and temperature fluctuations in the laboratory preclude the use of low repetition rate excimer lasers, which, in any event, would unnecessarily increase the sampling time. A final technical requirement of the system is the need for reliable synchronization between the CCD and the laser through the software driving the device. Precisely the same number of laser pulses must be averaged for each CCD frame to optimize the data. A suitable trigger input to the laser (typically TTL) must be available. A diffractive shearing interferometer based on a TuiLaser ExciStar S-Industrial excimer laser implements a stable common-path design, using only a minimum number of additional optical components compared to a more traditional mask qualification system. Thus the difficulties associated with stability requirements and material properties in the deep UV, such as absorption and scattering losses, are overcome. TuiLaser has carefully optimized its ExciStar S-Industrial argon fluoride excimer laser to meet the demanding requirements of PSM applications. Sophisticated design technologies including Solid State Switching and Corona Preionization of the discharge ensure long-term stability, excellent pulse-to-pulse stability, and a homogeneous beam profile. TuiLasers engineers have implemented an easy-to-use triggering protocol to allow appropriate synchronization of all components of the device.

Additionally, small versions are available which are preferable in applications with limited space. All stated performance values refer to application during daylight. For darkened rooms significantly lower minimum power ratings apply. Several stated maximum power ratings can be exceeded 2 to 3-fold when the exposure is only for split seconds or the card is moved forcefully. Due to their limited thermal capacity, none of the conversion screens are designed for continuous load in a direct beam. They should be moved slightly, which additionally also results in an improved picture quality.

CO2-laser robot with increased power With the arrival of the new laser robot RV16L-CO2 Reis Robotics opens up the market for laser material processing. Technology and concept of the robot now allows the application of CO2-laser sources having a capacity of 2 kW. Depending at the application, and due to high laser capacity and higher axes‘ speed of the RV6L-CO2 the cycle time may be reduced by half. The newly developed laser robot now extends the product range of Reis Robotics the leading systems integrator. Besides CO2-lasers, the advantages of this robot can also be used for fiber-guided robots (Nd:YAG- and diode laser). Thus, the new REIS laser robot is suitable for a wide range of applications in material processing of plastic and metal. Unlike the standard positioning, the CO2laser source now is mounted laterally onto the upper arm of axis 2. Due to its location close to the robot base, it is possible to move larger and heavier laser heads (up to 400 kg) without interfering with the available work envelope. Even with this new configuration, the entire dynamics and accuracy of the robot are maintained. In addition, because of the lower acceleration forces of the laser head, continuous operation is enhanced. The adjustable laser head is connected to the internal beam guidance via an universal interface. This interface allows the use of several different laser types from various manufacturers. In order to handle and ensure better accessibility for laser parts without risk of collision, axis 2 of the new REIS laser robot is not bent at a right angle.
New integrated beam guidance via four mirrors only With the new developed integrated beam guidance system, the unfocused laser beam is guided through the rotary axes 3 to 5 to the end of arm laser nozzle. Therefore, only four mirrors are required which are easily adjustable via cardan shafts. For transmission

of the laser capacities in the multi kilowatt range, the beam passage has a constant aperture of 35 mm. Each of the mirrors is air/water cooled and therefore very durable. The interior of the entire beam guidance system is completely sealed so that penetration of dirt particles is avoided. Application-specific processing optics can easily be adapted to axis 5 of the robot. The robot is modular in design and it’s work envelope is 2,500 mm. Reis Robotics offers other Robot models which can be used to accommodate a larger work envelope.

Premiere on the LASER 2005: The Perfect Laser for Microprocessing In microtechnology, thermal influences play a special role during processing. Laser beam sources for microprocessing have to exhibit special properties: diffraction limited beam quality, short pulses and the highest stability. TRUMPF has developed new solid-state lasers especially to meet these requirements. The TL Q laser series celebrates its premiere at the LASER fair 2005 in Munich. “In the last few years, a trend toward microtechnology is clearly emerging. TRUMPF has designed and developed a new laser series especially for microcutting, etching, drilling and structuring“, explained Jürgen Stollhof, a physicist, who works for TRUMPF, the world’s leading laser specialist. He is responsible for microprocessing applications. He knows what the main interests are: “For micro applications, a particularly high stability of pulse-to-pulse, output and beam position is very important. When it comes to these requirements, the TRUMPF TL Q lasers are setting new standards.” According to the specifications, the fluctuation in output power is below one percent and the maximum angle deviation of the exit beam is under 10 mrad. “We have developed the TL Q laser series in close cooperation with pilot customers to meet special requirements in the field of industrial microprocessing. And together with users and system suppliers, we would like to tap the potential of laser microprocessing.“ In the field of microprocessing, laser light is primarily used for the precise removal of material. Pulsed Q-switched diode-pumped lasers are used for this purpose. The very high peak pulse output of hundreds of kilowatts at a moderate average power level and the very brief pulse duration have
FIGURE 1: The average output of the TRUMPF TL Q lasers with a so-called Qswitch, can be converted physically either into high pulse energies or high repetition rates.
a positive effect on the processing results. Almost melt-free processing for the highest precision possible is the goal.
High pulse energies – high repetition rates The average output of up to 30 W of the TRUMPF TL Q lasers with a so-called Q-switch, can be converted physically either into high pulse energies or high repetition rates. The specific application determines which pulse properties are best. TRUMPF therefore offers lasers with two different laser-active media. While the TL 20-1 LQ with YLF-rod offers particularly high pulse energies of up to 4 mJ at 4 kHz, the TL 35-1 VQ with Yttrium-Vanadat (YVO4)-rod achieves repetition rates of up to 200 kHz. Nevertheless, with 30 kHz, up to 1 mJ of pulse energy is available. The pulse widths are dependent on the pulse energy and are between 15 and 80 ns.
A new technical feature of the diodepumped, Q-switched rod solid-state TRUMPF TL Q lasers ensures particularly high performance stability. The output is regulated not by controlling the excitation, but rather from pulse-to-pulse outside the resonator. The overall opto-mechanical resonator system is therefore in a state of equilibrium during operation. In addition to power stability, some micro applications, such as drilling, require an additional exact round beam profile. “Trumpf has succeeded in perfecting the beam profile. The roundness deviation is just a few percent, regardless of the output power and along the entire beam propagation”, noted Jürgen Stollhof. The advantage of a symmetrical beam is its consistent power distribution without fluctuations, before, during and after the focal point. “The symmetry provides for greater precision and reproducibility of the processing results,” explained Stollhof. TRUMPF microprocessing lasers are used in any application for which the benefits of touch-free, flexible and precise material ablation are evident.
Laser ablation of semi-conductors, ceramics or steel One example is the processing of crystalline silicone solar cells. In principle, they consist of one pn-transition in which the emitter is only a few nanometers thick. The production method causes a short circuit on the edges of the solar cells which reduces the available electric current. Up until now, this short-circuit has primarily been removed by means of machine grinding or by etching. In conjunction with scanner technology, the TRUMPF TL Q microprocessing lasers offer a new approach. The electric charge carriers are removed by vaporizing the material.

Technology transfer program for Fiber Bragg Grating TuiLaser and QPS Photronics introduce the first worldwide technology transfer program for Fiber Bragg Grating. TuiLaser, a world-wide leader in the manufacture of compact, high-performance excimer lasers and QPS Photronics, a principal innovator in volume manufacturing of Fiber Bragg Gratings (FBGs) have joined forces together to offer two comprehensive programs designed to quickly and easily transfer this valuable combination of technologies to third parties. “The objective is to make FBGs pervasive and affordable,” comments Peter Kung, president of QPS. “There are many industries that will now benefit from the special advantages that FBGs can offer.” FBG-based sensors have found many applications in remote and distributed sensing. In addition, FBGs are ideally suited for harsh environments that exhibit high temperatures, strong EMI or RFI, and explosive and corrosive gases. “Some of the advantages and the maturity of FBG technology have clearly been demonstrated by the volume deployment in telecom applications like pump lockers,” Kung notes. “What really sets an FBG apart is its long life; FBG products have passed and exceeded the Telcordia requirement of 25 years life expectancy. No other sensors can come even close to that sort of performance.” Two Technology Transfer Programs will be launched immediately: The first program is called a “Starter Kit”. It consists of an extremely flexible and versatile FBG writing station for products and process development. The Starter Kit is complete with TuiLaser’s acclaimed BraggStar S-200 compact excimer laser and all the necessary optical accessories. The Kit includes the beam delivery system, phase masks and mask holders, the fiber mounting, alignment, and transport mechanisms, plus fiber preparation tools, broadband light source, optical spectrum analyzer and a recoater. Everything that is necessary for creating a variety of FBGs for many applications is included. The Starter Kit is designed as a turnkey system especially to allow universities and research institutes a fast and easy access to their own custom FBGs.

QPS has been working with TuiLaser for many years and has identified the BraggStar S-Series as the most effective, affordable, and flexible tool for Fiber Bragg Grating production.
The second program is called the “Production Station”. It is a semi-automated FBG writing solution equipped with process recipes and automated test methods, software, and integrated reliability methods. The Production Station is product-specific and will facilitate the manufacture of industrial quantities of well-defined FBGs. Because the Production Station is designed for just that purpose, the included logistics software delineates a clear route to ISO9000 certification – an essential step if the system is to be used in a supply environment where large quantity orders can become a reality. QPS has been working with TuiLaser for many years and has identified the BraggStar S-Series as the most effective, affordable, and flexible tool for Fiber Bragg Grating production. Hence it is used as the light source for both: The Starter Kit and the Production Station. The use of the same laser in both kits facilitates the transition from device development to volume production. “Having worked with more than 20 of their lasers,” Kung states, “we are proud to partner with TuiLaser. Their lasers have always exceeded their specifications in performance and reliability, not to mention their excellent worldwide service.”
Petra Wallenta, PR Manager for TuiLaser, adds, “This is an ideal partnership: TuiLaser is a world-leading manufacturer of compact, high-performance excimer lasers and QPS is one of the few pioneering companies in FBG technology that have achieved successful volume production. The two strong forces in combination will guarantee our customers’ success.” Both Technology Transfer Programs are available immediately. Customers can also choose optional training and installation assistance and on-site service contracts.

DPSS laser – NUCLEON the future is wearable Rapid growth of laser applications for material processing in all leading industries was driven during the last decade by a fundamental technological transformation toward product miniaturisation. All laser system manufacturers were forced to achieve smarter and compacter designs to take into account industrial space limitations for increasing laser installations – while expectations continuously grew for performance, lifetime, reliability, and simplicity.
Driving the future Pure air-cooled, diode-pumped, highpower ND:YAG laser marking systems were pioneered by Compact Laser Solutions (CLS) back in the mid 1990s. Since then, the company has opened entirely new markets and applications. CLS technology now represents state-of-the-art design. Now, 10 years after these pioneering efforts, CLS is again ready to move the industry forward, by rolling out the very first handheld generation of high-power Neodymium DPSS laser systems. The launching of the internationally patented NUCLEON product series at LASER 2005 in Munich will move current technology beyond the limits of today’s product architectures. The reliability of these systems, designed for industrial field applications, sets a new standard.
Meeting the needs of industry The launch of the NUCLEON product family includes the infrared (1064 nm), Q-switched marking and precision-machining device PERPETUUM, which outputs up to 10-W continuous wave (CW) pulse repetition rates from 1 Hz to 50 kHz, with pulse length in the nano-second range. The frequency doubled version (532 nm), the RAPIDUS , provides up to 5-W CW, and operates Q-switched with up to 30 kHz repetition rates in the nanosecond pulse length range. The beam quality of both models is a fundamental TEM00 mode output, for near diffraction limited focussing (Fig. 1). The NUCLEON series additionally contains an ultra-compact, mobile 5-W CW in TEM00 mode, frequency doubled green (532 nm) enhanced beam source (Fig. 2). The applications are many and various.

FIGURE 1: The beam quality of SCRIPTUS und RAPIDUS is a fundamental TEM00 mode output, for near diffraction limited focussing.
They include micromachining and marking, surface as well as subsurface (for transparent materials, e.g. glass) engraving, nondestructive testing, cutting and trimming, laser ablation and OPO pumping, forensic applications, and uses involving pumping titanium-sapphire lasers. The revolutionary nano-design makes it remarkably simple to integrate these robust laser systems into all existing production lines and units, as well as those expected in the future. Integration limitations in industrial applications will disappear, owing to highly compact total system outer dimensions smaller than a DIN A4 sheet and total weight under 6 kg. With pump-diode rates in excess of typically 12,000 hours and practically maintenance-free pure air-cooling design, laser downtimes achieved will break all known performance barriers, including those for cost-effectiveness.
Advancing the frontiers No-limit mobility will result in a paradigmatic shift: laser to object instead of object to laser. In addition to the stationary industrial version of the NUCLEON product family, Compact Laser Solutions will release its pure mobility range. By virtue of their unique concept, all NUCLEON versions will be available as wearable, battery-powered handheld devices. The rechargeable battery package in a size of a human fist, continuously generates a 5-W (CW) green laser beam (532 nm) up to 1 hour, resulting in several hours of processing-time use in production practises.

Globo Welding Laser joining of plastics is becoming increasingly important. A technology of the future with sheer unlimited possibilities. Leister presented three concepts at the K show. Radial welding and simultaneous welding achieve extremely short cycle times. They are therefore ideally suited for integration into production lines. With Globo Welding, Leister was honored with this year’s prestigious Swiss Technology Award. In this concept, a laser beam is focussed at a point on the joining plane via an air bearing, frictionless, freely rotating glass sphere lens. The glass sphere not only focuses – it also serves as a mechanical claming tool. While the sphere rolls on the component,

The Globo concept can be used for processing sophisticated components in automobile production.
it applies continuous pressure at a point on the joining plane. This ensures that the laser beam is only incident at the point at which the contact pressure is applied. The air bearing glass sphere replaces the mechanical clamping device and expands the scope of laser welding for both continuous and for three-dimensional applications. The Globo
concept is especially suitable for robotic applications and can be used, for example, for processing sophisticated components in automobile production. (See Laser Technik Journal 2/2004, p. 35)

The Cobolt Blues 473 nm CW DPSS laser Cobolt AB, Swedish manufacturer of DPSS lasers announces the new single longitudinal mode version of Cobolt Blues 473 nm, available at 20 mW and 50 mW. The Cobolt Blues DPSS laser features low noise, excellent beam quality, long life time and compact size. The specifications on the beam characteristics match those of the Ar-ion laser, which makes it very suitable for direct drop-in replacement in e. g. flow cytometry and microscopy equipment. The combination of high output power and low power consumption also makes this laser the ideal choice in applications within laser displays, reprographics and fluid dynamics. Moreover, the narrow spectral bandwidth and long coherence length of the new single longitudinal mode version makes it particularly useful tool in spectroscopy, holography and interferometry applications.

Optical Gas Composition Sensors LaVision launches at LASER 2005 stateof-the-art fiberoptical concentration and temperature sensors for in-situ gas analysis. These innovative laser based sensors measure contactless with high temporal resolution fuel concentrations (hydrocarbons, alcohol and hydrogen), oxygen, their mixing ratio as well as their gas temperature. Only a minimal fiberoptical access is needed (keyhole technology). The analysis of fuel-mixture generation inside production engines is one application. LaVision’s optical spark plug sensors measure e.g. crank angle resolved the fuel-air ratios in combustion engines. A soot sensor records on-line and with highest sensitivity particle concentrations and particle sizes in the exhaust gas stream of these engines.
Other applications are leakage tests of e.g. pharmaceutical vials or sealed food containers. In gas turbines, reformers or fuel cells LaVision’s laser based sensors measure the gas composition of the major species (N2, O2, H2, H2O).
