(3)Measure and calibration of machine tool's rotary shaft.
(4)The error compensation table can be automatically generated according to the compensation methods set by users.
(5)Support manual or automatic environmental compensation.

3.Software:
(1)Friendly user interface
(2)Rich application modules

Laser interferometer uses light wave as the carrier, which can definition the length of meter by its wavelength and recognized as a measuring instrument with high precision & sensitivity, it’s widely used in the field of high-end manufacturing.

 

SJ6000 can output laser with high precision (0.05 ppm) and long-term stability quickly (about 6 minutes) by Dual-longitudinal thermal frequency stabilization technology, which has powerful anti-interference performance. It has many advantages of measurement such as high accuracy, wide range and high resolution at the highest measuring speed. With different optical lens, high precision measurement of geometric parameters such as linear length, angle, straightness, perpendicularity, parallelism and flatness is achievable.
