Spectral Range SWIR (900 - 1700 nm)

Phasics SID4-SWIR wavefront sensor

The SID4-SWIR wavefront sensor integrates Phasics' patented technology with an InGaAs detector. Thanks to its high spatial resolution (80 x 64 phase pixels) and high sensitivity, it offers accurate wavefront measurement from 900 nm to 1.7μm. The SID4-SWIR is an innovative solution for testing SWIR optical systems used in optical communications, inspection instruments or night vision in military and surveillance devices.
