Chotest Laser Interferometer Measurement System SJ6000 Series

High Precision of Measurement

Resolution is up to nanoscale based on the technology of laser interference

With high-precision environmental compensation modules, influences on measuring result which result from temperature, atmospheric pressure, relative humidity, material temperature and other environmental factors are eliminated;

Ensure long-term frequency stability of laser by using the laser thermal frequency stabilization control system;

Design of separating interferoscope from host avoids heat distortion of interferoscope, which ensures the stability of interference optical path.

Whole Parameters Measurement

Measure linearity, angle, straightness, perpendicularity and other geometrical parameters

Test the linear positioning accuracy and repeated positioning accuracy of guide rails for CNC machine tools, coordinate measuring machines and other precision motion equipments;

Test the pitch angle, swing angle, perpendicularity and straightness of the guide rails, in addition it can calibrate axis of rotation of machine tools.

Error Compensation

According to compensation settings by user, the system automatically generates error compensation table for calibration of machine tools.

Dynamic Measurement

With functions of Dynamic measurements (displacement-time curve, velocity-time curve, acceleration-time curve), amplitude measurement and frequency analysis, it can analyze vibration test of machine tool, dynamic characteristics of ball screw, response characteristics of drive system, dynamic characteristics of guide rail and so on.
