In ultra-high precision optical inspection, the temperature rise and data drift caused by long-term continuous measurement have always been bottlenecks restricting scientific research and industrial applications. The FIS4-UHR-C ultra-high resolution wavefront sensor (refrigerated version), developed by a research team led by Professor Yang Yongying of Zhejiang University, integrates a liquid-cooling system on top of ultra-high resolution measurement, achieving a dual breakthrough of 'ultimate accuracy + long-term stability'.

Based on four-wavefront transverse shearing interferometry, this sensor requires no reference mirror and can acquire bidirectional wavefront information in a single acquisition, capturing the ultimate details of optical surface shapes. Simultaneously, the built-in liquid-cooling system effectively suppresses data drift caused by temperature rise and can be used with a dedicated heatsink, ensuring stable and reliable operation even during long-term continuous measurement. It is suitable for scenarios such as laser beam wavefront detection, adaptive optics, planar surface shape measurement, optical system calibration, optical window inspection, optical plane and spherical surface shape measurement, and surface roughness detection.

The fully self-developed supporting analysis software, developed concurrently with the hardware, further achieves a dual upgrade in performance and user experience. The software features a user-friendly and intuitive interface, supporting simultaneous visualization of multi-dimensional data such as 3D topography, contour maps, phase maps, and focal spot intensity. It can dynamically acquire and present wavefront changes in real time. A comprehensive data analysis module is built-in, automatically outputting core measurement parameters such as PV, RMS, POW, PSF, OTF, and MTF.

The FIS4-UHR-C ultra-high resolution wavefront sensor (refrigerated version) is entirely domestically developed, with performance comparable to leading international brands. It also offers rapid localized support and flexible customization services, helping users overcome the technical limitations and service delays associated with overseas brands. This is a tangible answer from Chinese manufacturing to the global high-end optoelectronic market.
