Spectral Range SWIR (900 - 1700 nm) eSWIR (1.7 - 2.35 µm)

Phasics SID4 eSWIR wavefront sensor

The SID4 eSWIR wavefront sensor integrates Phasics' patented technology with a T2SL detector and is the only high-resolution wavefront sensor covering the extended SWIR range from 1.2 to 2.2 µm. SID4 eSWIR is an innovative solution for testing SWIR sources and lenses used in optical communications, inspection instruments, or night vision in military and surveillance devices.
