  Details:

The Bojiong FIS4 UHR wavefront detector was developed by a team of professors from Zhejiang University and Nanyang Technological University, Singapore. It uses patented random coded four-wave diffraction technology to achieve single-channel wavefront self-interference. Interference occurs at the back-image plane position, with low requirements on light source coherence and no phase shift. Ordinary imaging systems can achieve interferometric measurement. It has ultra-high shock resistance and ultra-high stability, and can achieve nanometer-level precision measurement without vibration isolation. Compared with the microlens array Hartmann sensor, it has more phase points, wider adaptive band range, larger dynamic range, and lower price.

It aims to assist scientific research and high-precision industrial scene development. Higher resolution can provide more detailed information in wavefront detection. Ultra-high resolution 512 × 512 (262144) phase points, 400-900nm wide spectral response, 5 frames of full-resolution real-time 3D result display, providing ideal wavefront sensing measurement tools for laser beam wavefront detection, adaptive optics, plane surface measurement, optical system calibration, optical window detection, optical spherical measurement, surface roughness detection, surface micro-contour, etc.
