FIS4-UVUltraviolet Wavefront Sensor

In optical detection within the ultraviolet spectrum, traditional wavefront sensors often encounter challenges such as mismatching response wavelengths, rapid signal attenuation, and difficulties in ensuring measurement accuracy. The FIS4-UV wavefront sensor, developed by a research team led by Professor Yang Yongying from Zhejiang University, is specifically tailored for ultraviolet applications, making high-precision ultraviolet wavefront measurement a reality.

This sensor is suitable for applications such as laser beam wavefront detection, optical system aberration measurement, optical system calibration, micro-etching topography measurement, adaptive optical path, metasurface wavefront measurement, planar (wafer) surface shape measurement, and optical spherical surface shape measurement. Based on four-wavefront lateral shearing interferometry technology, it can obtain bidirectional wavefront information with a single acquisition without the need for a reference mirror. It is specially optimized for the ultraviolet band, featuring nanometer-level accuracy, wide dynamic range, and real-time processing capability. At the same time, it inherits the common-path interferometry architecture, which provides strong adaptability to environmental vibration and temperature and humidity fluctuations, enabling stable and high-precision measurements in ordinary laboratory and industrial environments.

Equipped with fully self-developed analysis software, users can enjoy an efficient experience throughout the entire process from data acquisition to analysis output: a friendly and intuitive interactive interface supports simultaneous visualization of multi-dimensional data such as 3D topography, contour maps, phase maps, and focal spot intensity, and the real-time dynamic acquisition function allows for the observation of wavefront changes throughout the entire process; a comprehensive built-in data analysis module automatically outputs core measurement parameters such as PV, RMS, POW, PSF, OTF, and MTF, making complex UV wavefront data processing efficient and intuitive.

The FIS4-UV ultraviolet wavefront sensor has achieved full-chain domestic self-development from core algorithms to hardware and software, with performance comparable to top-tier international products. Relying on localized rapid response and flexible customization services, it successfully breaks the technical barriers and service restrictions of overseas brands. With its independent and controllable technological strength, FIS4-UV is redefining the boundaries of global ultraviolet optical measurement.
