Optical Collimator System W420-3 is designed for checking Automatic Level, Optical Theodolites, Electronic Theodolites, Total Stations and other Optical Levels.
*Introduction:<o:p>
1) This model of equipment adopts totally three collimator tubes which have the focus of 420 and been
designed with plunge angle, elevation and collimation horizontal angle. <o:p>
2) The collimator tube is equipped with a long horizontal bubble with the precision to be 10", which can
significantly improve CCT's inspection precision.<o:p>
3) The collimator tube is equipped with up/down and right/left tuning device, therefore easy for
customers' usage, installation, commissioning and inspection. <o:p>
4) The collimator tube adopts the latest long-life "cold" light source, which intensity may be
tuned according to customers' requirements and indoor luminance. The source produces
viridescent lights, which are comfortable for seeing. <o:p>
5) On the lifting platform, the threaded rod allowing 26cm lifting range runs smoothly and stably, and with
different configuration, enables customers to operate readily and easily. <o:p>
6) The fixed, integrated instrument center screws on the lifting platform are common in both metric and
British systems (two-in-one), and can be combined for checking different foreign and
domestic measuring instruments.<o:p>
7) The foundation is designed and installed with 4 leveling wheel, and at the bottom, 4 round pads can
increase the ground force-carrying surface and the stability. The whole platform is
available for leveling and moving. <o:p>
8) The equipment is designed with small form factor and looks decent and charming. The total
weight is 120kg and the equipment stands very firmly. <o:p>
