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

Phasics SID4-eWIR 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 0.9 to 2.35 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.
