UV wavefront sensor 200-450 nm

BOJIONG Optoelectronics has always been dedicated to wavefront interference detection technology, and now introduces a new generation of Ultraviolet Four-wave Interferometric Sensors, providing excellent solutions for universities and research institutes. Our products and services are widely used in optical manufacturing, aerospace, biomedical, and energy research, helping customers conduct precise measurements and analyses of optical performance to improve product quality and production efficiency. In recent years, we have continuously expanded our production scale, strengthened our technical capabilities, and established a comprehensive corporate operating mechanism. BOJIONG sincerely invites customers from both domestic and international markets to collaborate with us to achieve brilliance together.

The BOJIONG UV wavefront sensor 200-450 nm integrates patented random coding four-wave diffraction technology with an ultraviolet camera to perform interference at the rear image plane, necessitating low coherence from the light source and eliminating the need for phase shifting. Utilizing the ultraviolet imaging system, this sensor enables real-time wavefront measurement with exceptional vibration resistance and stability, achieving nanometer-level precision without the need for vibration isolation.
