Laser measuring system RT-100

OPTODYNE's RT-100A Automatic Rotary Table Calibration Package is an add-on to Optodyne's MCV-2002 Linear and Angular Machine Calibration Instrument (or the enhanced MCV-4000 model). The combined system can be used to calibrate rotary tables or stages with high accuracy. Optodyne's method is different from the conventional comparative approach using a laser interferometer, where the test device is compared to the known inaccuracies in a master rotary calibrator. This comparative approach is both very expensive and difficult to use. Optodyne's machine calibration instruments are based on our proprietary and patented Laser Doppler Displacement Meter (LDDM) Technology. The dual-beam laser system can be used by itself to measure a rotational angle up to ± 10 degrees. With the supplied small turntable, the angular measurement range can be extended to 360 degrees in increments up to 10 degrees. Hence, the combinations can be used to calibrate rotary tables or stages.
