Spectral Range VIS - NIR (400 - 1100 nm)

Phasics SID4-UHR wavefront sensor

SID4-UHR Ultra-High-Resolution wavefront sensor is adapted for optics metrology needs. It combines the SID4 ease of implementation with high sampling and resolution. Its large aperture allows to get a live wavefront measurement over the complete sample under test. The SID4-UHR is optimized for surface inspection (roughness, high frequency defects detection...) and optical components characterization (lens, objective, aspherical and freeform optics...). Built with a high-performance camera it provides incredible precision for laser characterization. The 512 x 512 (option 666 x 666) phase map sampling with such compactness make the SID4-UHR a unique tool for optics and laser metrology in both research and industry fields.
