Spectral Range SWIR (900 - 1700 nm)

Phasics SID4 SWIR HR wavefront sensor

The SID4 SWIR HR wavefront sensor integrates Phasics' patented technology with an InGaAs detector. Thanks to its ultra-high spatial resolution (160 x 128 phase pixels) and high sensitivity, it offers accurate wavefront measurement from 900 nm to 1.7 µm. SID4 SWIR HR is an innovative solution for testing SWIR optical systems used in optical communications, inspection instruments or night vision in military and surveillance devices.
