Manual Abstract The new Mystiqe MultiColor Projector series is a state of the art lasershow device, which eliminates the need of watercooling or 3-phase power. The projector comes in different output power versions and dimensions, such as: Mystiqe 300: Mystiqe 600: Mystiqe 1000: Mystiqe 1500: Mystiqe 3000: >300mW RGB, visibility 600mW gas whitelight > 600mW RGB, visibility 1.2W gas whitelight >1W RGB, visibility 2W gas whitelight >1.5W RGB, visibility 3W gas whitelight >3W RGB, visibility 6W gas whitelight Depending of the projector, different galvos are mounted. Please refer to actual product brochure for details. Further highlights are the brandnew design, the sandwich mounting plate for good mechanical stability and also less weight. Brand new designed optical mounts ensure a very good optical stability over long terms. As the first company in the world, MediaLas announced an RGB whitelight projector late 2002, and presented the design early 2003 on Frankfurt´s Pro Light & Sound trade show. In the meantime, MediaLas sold and manufactured a large number of MultiColor systems and earned lots of experience in designing a stable and handy whitelight system. The Mystiqe series was born. By using a sandwich heat exchanger instead of single airflow devices, the optical section has been completely seperated from any airflow or heatsink, and comes dust sealed with an anti-reflective coated output window. Techniqe of Mystiqe laser projectors All Mystiqe projectors are developed, tested and manufactured in Germany by MediaLas. Each projector and it´s components run through extensive tests and alignment procedures, to ensure a long and stable lifetime. The sandwich heat exchanger not only increases stability, but also reduces thermal effects on the lasers and optics dramatically. Furthermore, active cooled lasers and laser diodes are used. Due to the nature of high-tech optical equipment used in the optical table section of the Mystiqe, the devices are more sensitive to external influences tha n normal lighting devices. Please use this manual for basic hints and tricks for maintenance of Mystiqe Laser Systems. In case of any further help, please contact our service staff. Actual phone numbers and contact information is provided on our website at www.medialas.com Specification of laser output power All Mystiqe laser systems´ output power is specified "after the laser", as stated in brochures and websites. The laser output power can be measured inside the housing, after beam combination and collimation BEFORE the scanner mirrors and output window. The procedure is quite simple: Use a 5V signal for all laser inputs, do NOT use a scanning pattern from any kind of software, cause it will disturb your measurement results. Apply 5V signal to positive color inputs pin 5,6,7 and apply ground to negativ color inputs pin 18, 19 and 20. Now use a pyro power meter (no laser check!) before the scanner. Here you should have the specified minimum output power. Adjusting the scanners On normal circumstances and under normal operating conditions, there is no need to readjust the scanners. If, for any case, a readjustment has to be done, please refer to attachements "Scanner tuning". Aligning the optical color mixing device Depending on the type of Mystiqe Laser system, there are two different color mixing techniqes used. Systems Mystiqe 300 to Mystiqe 1500 contain a 3-way dichroic mixing techno logy, while the models Mystiqe 2000 and Mystiqe 3000 mixed with a new developed loss- less prism technology. Both technologies require different strategies in mixing and aligning. After heavy transportation, or after large temperature differences, coming from outside cold ambient to an inside warm ambient, it might be necessary to realign the optical setup inside. Under normal circumstances, the optical section is maintenance free, and does not need to be realigned. Preparations Remove the top cover by removing all screws on top and front of the cover. Lift the cover and unplug the earth connector on the left power supply section of the Mystiqe. Be sure to work in a dust- free ambient, so the optical section is not contaminated. Now safely store the top cover and avoid touching the output window. During aligning process, also make sure not to touch any optical surface with sour fingers. Inside the Mystiqe, high quality optical components are used, and not all optical surfaces can be cleaned the usual way. Most of the mirrors are very high reflective protected silver mirrors, cleaning is not recommended. If, in any case, the surface is dirty, it is recommended to replace the mirror. Apply an input signal to the DB25 ILDA connector on the back of the Mystiqe. You can either do this with an external power supply or a standard laser software by projecting a white dot or small circle. Mystiqe 300, 600, 1000 and 1500: Basically there are three devices for red, green and blue color. Depending on output power and setup of the Mystiqe projector, there might be up to 10 lasers, which are coupled and aligned to one single beam. But in any case, each single color is mixed to one beam, before it enters the main optical mixing section. Procedure is quite easy, but should only be done by an experienced service technician. All color lines must be parallel from the last dichroic filter on the red laser to a distance of minimum 10m projection size. Try to adjust all laser sources to exactly the same height over ground plate. All beams must be on the same spot on the final dichroic filter. At the same time, all colors must be on the same spot after a beam distance of minimum 10m. The green laser beam is your reference of the optical mixing system. Adjust the green beam with the mirror mounts. Make sure, the beam is parallel to the base, and hits the galvo mirror properly. Now adjust the blue laser line in the same procedure. Shift the beam with the first mirror mount, adjust the angle with the second mount. Align both beams properly on top of each other, parallel onto the galvo mirror mount, and, at the same time, parallel in far distance. Use the same procedure on the red laser. Finally, all single beams and colors should match on the galvo mirrors and also after a distance of 10-20m. Once the system is aligned, it should not misalign again. During alignment procedure, please check all mirror mounts for proper function. Mystiqe 2000 and 3000: Mixing technology of Mystiqe 2000 and 3000 is different, to ensure low losses and minimum possible dimensions of the laser devices. Always make sure not to touch any optical surface! The green laser beam is the reference of the optical mixing system. Adjust the green beam by adjusting the mirror S4, that it fits well on the galvo mirrors. The two red lasers are mixed and added in the polecube P1. Adjust the mirror S1 to put the points of Laser red1 and red2 in P1 to one visible spot. Now adjust the angle and position of P1 to get one spot of red in a far distance. By adjusting this polecube, both red beams will become one single beam. You may use a separate laser mirror to deflect the beams out of the Mystiqe housing onto a distance. The mirror S2 is responsible for aligning the red beam over the green beam in a close distance. S3 is responsible for the longer distance. Adjust S2 to move the red beam onto the galvo´s mirrors. No adjust S3 to align both green and red beams on distance. Repeat the same procedure with S2 and S3, until both beams are aligned on galvo mirrors and also on far distance. You may use a separate laser mirror to deflect the beams out of the Mystiqe housing onto a distance. The two blue lasers are mixed and added in the polecube P2. Adjust the mirror S6 to put the points of Laser blue1 and blue2 in P2 to one visible spot. Now adjust the position of P6 to get one spot of blue in a far distance. You may use a separate laser mirror to deflect the beams out of the Mystiqe housing onto a distance. The mirror S7 is responsible for putting the blue beam together with the other beams in a close distance. S5 is responsible for the longer distance. If the beams are directly at the prism put together, just turn the mirror S5. In other case turn S7 and then S5. Finally, all single beams and colors should match on the galvo mirrors and also after a distance of 10-20m. Once the system is aligned, it should not misalign again. During alignment procedure, please check all mirror mounts for proper function. Cleaning the optical surfaces Some of the optical surfaces in your Mystiqe system are made for very high reflectivity, such as mirror surfaces etc. Reflectivity of more than 98% is obtained only, if the mirror surface is free of dirt or fingerprints. Also, lenses and filters depend on a clean surface for maximum efficiency. Unfortunately, a cleaning of the silver mirrors in your Mystiqe is only possible once or twice. Since the optical section is dust free and also air free, there should not be any contamination of these mirrors. During alignment process, and any time, the case top is lifted or unmounted, please make sure, to work in a clean environment with minimum dust particles. The lesser your particles, the better your results. In the unlikely case of a dirty or contaminated mirror surface, you can try to clean the mirror with simple glass cleaner and a very mellow paper tissue. Do not use any alcoholic cleaner such as Aceton or Methanol! If cleaning is not possible, the mirror has to be exchanged. Other optical coated surfaces can be cleaned the same way, with standard glass cleaner and a mellow paper tissue just as Kodak Lens Paper. Make sure not to leave any traces of the cleaner fluid on your surface. Do not rub or press on the surface of the mirrors. Color filters can also be cleaned easily, since the coating is much harder than the ones on the mirrors. Make sure to avoid any rough treatment. MicroAmp Tuning and adjustment Introduction The MicroAmp is currently the smallest and fastest scanamp for CTI´s 6800 or 6210s on the world market. It´s new technology allows to scan up to 60k with selected galvanometers, at a reduced scanangle of 4° optical. But even at large angles, the scanrate is increased. The standard delivery package contains driver and input cable. The driver is presetted to CTI 6800 galvos, but has to be retuned slightly before first use. This can be done by using the three adjustment trimmers on the drivecard. The cable High speed galvanometers demand for special cables, which are shielded and separated between motor and position detector. Cable lenghts up to 100cm are allowed. We recommend a cable lenght of maximum 50cm. Power source Power source is slightly critical and has strong influence on speed and quality of the complete scanner system. Even if a standard transformer with a bridge and caps will do, MediaLas recommends a stabilized or switched power supply. The MicroAmp is able to run between +/20VDC to +/-30VDC, at 1A each. The speed between 20V and 30V is different, especially at small step angles. While MediaLas uses 24V switching power supplies, a speed enhancement can be reached at 30V. If you use transformer and bridge, then make sure to have minimum 10,000 uF caps per voltage, better 40,000 uF, parallel with a 100uF for fast peaks. Do not use extra capacitors at switching power supplies. Polaritiy of connecting power to the driver is important. No warranty if connected incorrect. The measuring procedure The MicroAmp was measured with CT6800HP, make 1999, passice cooled. Laboratory power supply, room temperature. Windows PC with LD Pro, 12/30k ILDA testframe. Later we did some measurements with 6210s, connector style, passive cooled. The speed differed from what we measured with the 6800s. Mainly this was caused by the mirrors and the different connector, which has a slightly higher resistance than the 6800 connector. We then changed to the older suttering style 6210s and found a speed increase at small step angles. Deflection angle (6800) 25° optical deflection 15° optical deflection 8° optical deflection 5° optical deflection Operating voltage +/- 24V +/- 24V +/- 30VDC +/- 30V Speed 25.000 pps 30.000 pps 45.000 pps 52.000 pps Deflection angle (6210) 25° optical deflection 15° optical deflection 8° optical deflection 5° optical deflection 4° optical deflection Operating voltage +/- 24V +/- 24V +/- 30VDC +/- 30V +/- 30V Speed 28.000 pps 35.000 pps 50.000 pps 57.000 pps ~ 60.000 pps The ILDA standard Driver is set too fast or output speed of computer is too slow. The inner circle is larger than the green square. Driver and output speed matches together. Driver is too slow or output speed of computer is too high. Readjust driver or slow down computer. Adjustments Standard configuration shows 7 adjustment pots, 4 of them are necessary for the user. The small pots, which are placed inside the board, shoud not be changed in setting. These are necessary for linearity and other galvo specific settings. Basic adjustments The MicroAmp comes already pre adjusted and needs to be set up for the galvo only in small areas. Every galvo is different, so minor adjustments are needed. For this, the ILDA test pattern is used, also a setup of the galvos in XY with a laser. If the driver is totally deadjusted, this will be the procedure to retune it: • • • • • • • • Size, Servo-Gain, Damping und HF-Damping are adjusted counter clockwise to their left zero position. Now turn LFD 5 full rounds clockwise to right. Connect computer with ILDA test pattern, run it at approx. 20kpps. Power on the amplifiers. Slowly open the servo gain (clockwise). The mirror of the galvo should move now to its middle position. If yes, turn two rounds clockwise. Slowly open the size until you see the galvo moving. Increase servo gain until you see overshoots. Correct it with LFD. Decrease undershoots by opening the HFD pot slightliy clockwise. Remove gain/LFD procedure and correct with HFD, until you the ppicture looks satisfying. Increase speed of test patterns and readjust for optimized picture. Inverting of axis By using the jumpers at the inputs, each driver can be inverted easily. This can be done during scanning also. Just pull out the jumpers and put them in at 90° rotated. Heatsinking The MicroAmps are relatively insensitive to heat, since the power stage contains a overheat shutdown. To assure full function, the MicroAmp should be used with the attached heatsink. If you want to save space, remove the heatsink and mount the amp on a metal housing, to remove the heat from the power stage. The temperature at the heatsink should be below 70°C (170°F) In / Outputs On the 8pin connector, all necessary in and outputs are available. Here is the power supply connected, the symmetric inputs and also the feedback outputs for the CAT-SAFE board. We recommend a ground free operation between computer and drivers. ATTENTION! Do not use FEEDBACK as inputs. This will instantly destroy your galvanometers! Important hints • • Do not remove the driver board from its mounting bracket. This additional metal plate is needed for ground and increases stability of the driver. The bracket is isolated from ground. Do not use cheap and unshielded cable. We recommend to use the MicroAmps only with MediaLas cables. These cables are tested and designed for this driver. WE do not offer any warranty, if other cables are used. • • • If the galvos gets very hot (above 48°C / 125°F), switch off the system and check for errors or problems. Use approbriate heatsink for the galvos. Do NOT run them without heatsink!! If the fuses blow continously, do not replace them with a higher value. Check for possible errors. The maximum current per phase should be in average below 700mA. If it is higher, there can be a problem, which can result in overheating the galvos.
