WT-85 Goniometer

PI WT-85
    • Uni-directional repeatability down to 0.0005 °
    • Maximum speed 15 °/sec
    • Load capacity up to 2 kg
    • Integrated limit switches
    • Optionally: angular scale
    • Clear aperture 30 mm
    • Precise, smooth continuous 10° motion
    • Together with WT-100 one centre of rotation

The goniometer stages WT-85 and WT-100 are designed for all tasks where conventional rotation stages cannot be used due to limited space conditions or where a clear aperture is needed. Typical applications are metrology tasks in the area of laser technology and radiology. The goniometer stages WT-85 and WT-100 are designed to work together. When mounted orthogonally to each other they have a common center of rotation. The WT-85 has a 30 mm clear aperture. A unique driving mechanism insures a very quiet and smooth motion. It is driven directly by a DC or 2-phase stepper motor and can achieve a relatively high speed. The WT-85 stages are available with optional optical angular scales and are equipped with two limit switches.
