Laser Interferometer Measurement System Featuring 0.05ppm Precision and 1nm Resolution

Laser interferometer is recognized as a high precision, high sensitivity measuring method that uses light wavelength as a criterion, widely used in high-end manufacturing domains. 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 of laser dual-longitudinal mode and geometric parameters interference optical path design, the SJ6000 delivers long-term stable, high-precision (0.05ppm) laser output quickly (approximately 6 minutes) with powerful anti-interference performance. With different prism modules, it can measure linearity, angle, straightness, flatness, perpendicularity, and analyze dynamic characteristics.
