Description :

HASO™4 FIRST is the ideal choice for results driven professionals in domains including adaptive optics, optical process optimization, laser beam characterization, and many others. Thanks to our patented technology, the HASO family by Imagine Optic are world’s only sensors with no bias error, keeping its phase accuracy on any measured intensity profile (Gaussian, Top-Hat, hyper Gaussian, etc.).

HASO4 FIRST is delivered with WaveView, our industry leading wavefront metrology software. With just a few clicks, you can perform wavefront measurement, wavefront reconstruction as well as visualize the spot image and raw camera data.
