Imaging Cameras & Sensors – Wavefront Sensors
Ultra-Violet (UV) High Resolution Wavefront Sensor
Precision in ultraviolet wavefront sensing is critical for today’s advanced optical research and high-energy laser systems. The SID4-UV HR Wavefront Sensor from Phasics is designed to meet this demand. Equipped with patented QuadriWave Lateral Shearing Interferometry (QWLSI), this high-resolution sensor enables real-time, single-shot measurement of wavefront and intensity from UV sources with nanometric accuracy.
United Spectrum Instruments distributes the SID4-UV HR exclusively in India. It is the ideal solution for UV beam diagnostics, optical component testing, and adaptive optics control in scientific and industrial settings.
Unlike conventional sensors, the SID4-UV HR is optimised for ultraviolet wavelengths, offering superior performance for applications involving excimer lasers, UV lithography systems, and high-power laser facilities. Its compact, camera-like design integrates easily into both R&D environments and production setups.
By capturing >24,000 data points in a single shot, the sensor delivers high-fidelity phase mapping, enabling users to assess beam uniformity, alignment precision, and optical surface quality across the 190–400 nm UV spectrum.
