FIS4-HR-C High-Resolution Wavefront Sensor(Refrigerated version)

In high-precision optical detection, the temperature rise of equipment under prolonged operation has always been a key pain point affecting measurement stability. The research and development team led by Professor Yang Yongying of Zhejiang University has launched the self-developed FIS4-HR-C high-resolution wavefront sensor (Refrigerated version), providing a more stable solution for the field of high-end optical detection.

This sensor is suitable for beam wavefront detection, adaptive optics, planar surface measurement, optical system calibration, optical window plate detection, optical plane, spherical surface measurement, and surface roughness detection. Based on the principle of four-wavefront lateral shearing interference, it achieves wavefront measurement without reference mirror, single-shot acquisition in both directions, nanometer-level accuracy, wide dynamic range, and real-time processing. At the same time, it adopts liquid cooling method to effectively suppress data fluctuations caused by temperature rise during equipment operation, greatly improving the stability of long-term continuous measurement, and perfectly adapting to applications with higher requirements for wavefront stability.

The fully self-developed supporting analysis software, developed in synchronization with the hardware, has achieved a dual upgrade in performance and user experience. The software features a user-friendly and intuitive interactive interface, supporting synchronous visualization of multi-dimensional data such as 3D topography, contour maps, phase maps, and focal spot intensity, enabling real-time dynamic acquisition and presentation of wavefront changes. With a comprehensive built-in data analysis module, it can automatically output core measurement parameters such as PV, RMS, POW, PSF, OTF, and MTF. The software has a low barrier to entry, providing users with an efficient experience throughout the entire process from data acquisition to analysis and output.

As a fully domestically developed product across the entire supply chain, the FIS4-HR-C high-resolution wavefront sensor (Refrigerated version) not only achieves performance comparable to or even surpassing similar foreign products, but also provides end users with rapid-response localized technical support and customized services through an independently controllable technical architecture. This helps customers achieve localization substitution of core components, enhancing the overall performance and competitiveness of the equipment. This is our solid contribution to the transformation and upgrading from 'Made in China' to 'Intelligent Manufacturing in China'.
