Optical Collimator System W420-3 is designed for checking Automatic Level, Optical Theodolites, Electronic Theodolites, Total Stations and other Optical Levels.
*Introduction:
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.
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.
3) The collimator tube is equipped with up/down and right/left tuning device, therefore easy for
customers' usage, installation, commissioning and inspection.
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.
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.
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.
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.
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.
