Laser Interferometer Measurement System with 0.05ppm Accuracy and 1 nm Resolution

Laser interferometry is recognized as a high-precision, highly sensitive measuring method that uses light wavelength as a criterion, widely used in high-end manufacturing. The SJ6000 laser interferometer system incorporates a high-frequency Helium-Neon laser generator from a USA supplier, high-precision environmental compensation modules, advanced laser interference signal processing, and a high-performance computer control system.

Utilizing thermal frequency stabilization technology with laser dual-longitudinal mode and geometric parameters interference optical path design, the SJ6000 delivers long-term stable, high-precision (0.05ppm) laser output within approximately 6 minutes, with powerful anti-interference performance. With various prism modules, it measures linearity, angle, straightness, flatness, perpendicularity, and analyzes dynamic characteristics.
