HASO Multispectral

VIS-NIR spectrally-resolved wavefront sensor

A very accurate, fast and versatile instrument, the HASO Multispectral is the first-ever spectrally-resolved wavefront sensor. Its wide spectral range coupled to the powerful HASO4-Broadband enables full characterization of TW/PW lasers’ performances, and optimization of the peak intensity on target. The HASO Multispectral builds on 25 years of expertise at Imagine Optic in providing high-end Shack-Hartmann sensors for metrology, adaptive optics and lasers.
