Product Description

Optical Collimator System W420-3 is designed for checking Automatic Level, Optical Theodolites, Electronic Theodolites, Total Stations and other Optical Levels.



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>
