HASO Multispectral

VIS-NIR spectrally-resolved wavefront sensor

Spectrally resolved wavefront sensor A very accurate, fast and versatile instrument for wavefront sensing , 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.

HASO Multispectral Wavefront Sensor

The Spectrally resolved wavefront sensor is the first-ever wavefront sensor on the market that has the ability to resolve the frequency on a broad 550 – 1000 nm spectral range. Coupled to our standard HASO4 Broadband, it enables full characterization of TW and PW class lasers in the goal of optimizing peak intensity on target.

The HASO MULTISPECTRAL system is engineered to have a simple setup and alignment process, necessitating only a 5 mm collimated beam that is attenuated. It can handle any numerical aperture by including an optional module. The HASO4 WFS, equipped with a self-aligning magnetic mount, can be effortlessly used as a standalone sensor for diagnostic purposes or to track an adaptive optic loop. When relocated to the MULTISPECTRAL platform, the HASO4 WFS is quickly realigned using SpotTrackerTM.
