The principles of optics The magnification of an optical instrument indicates how much closer a target appears to the user when looking through the instrument compared when looking to the target without instrument. The larger the magnification is chosen, the smaller the field of vision and the
light intensity get. The objective aperture also has a great influence on the light intensity. The larger the objective aperture, the better is the light intensity of the object, i.e. the brighter the image.
Levelling instruments in general
Selecting the right Nedo level
Levels are used to create a horizontal line of sight in order to determine differences in height. The main components include a telescope with crosshair which can rotate around the vertical axis, a horizontal circle for marking off the angles, and the bubble which helps to keep the instrument in a horizontal position with a tribrach. Automatic levels also feature a compensator mechanism which will adjust the level to an exactly horizontal position within a small working range. The compensators are equipped with a damping system. In practice, air-damped and magnetically damped compensators have become generally accepted. The air-damped compensators are of better quality whereas magnetically damped compensators are more favourably priced.
Nedo offers a range of various automatic builders’ levels: X-Series: F-Series: E-Series:
premium-class builders’ levels for the most demanding requirements modern builders’ levels with robust optics and rugged design reliable builders’ levels for pricesensitive users
Selecting the right magnification As a rule of thumb, the magnification should be the target distance in metres. Levels with a 24x magnification are ideal for applications on the construction site. An interesting alternative from the aspect of cost is a level with a 20x magnification. Levels with a 28x or 32x magnification are used mainly for engineering and surveying purposes.
Each Nedo builders’ level is carefully checked and adjusted before dispatch. All Nedo builders’ levels are accompanied by an inspection record as part of the scope of delivery.
Theodolites A theodolite is an instrument used for precise measurements of vertical and horizontal angles. On construction sites, theodolites are further used for making exact alignments e.g.
when foundations are cast and for checking if formwork and facades are perfectly vertical. The precision of a theodolite is given in arcseconds.
Electronic theodolites with digital displays have become generally accepted as they provide easy read-offs.
