Vacuum Datasheet

The goniometer stages WT-120 and WT-90 are designed for all tasks where conventional rotation stages cannot be used due to limited space conditions. Typical uses are applications in the area of laser positioning and radiology. The goniometer stages WT-120 and WT-90 are matched to work together. When mounted orthogonally to each other they have a common center of rotation. WT-120 is equipped with a ground bearing guide. The ground and hardened worm screw and worm gear combination produces a very quiet and smooth motion. The stages are directly driven by a DC or 2-phase stepper motor and can achieve a relatively high speed. WT-120 stages can be equipped with an optical angular scale system and have two limit switches.
