ImSpector NIR/SWIR


High performance imaging spectrograph covering IR ranges:

NIR 900-1700nm  SWIR 1000-2500nm

Imspectors designed for NIR (900-1700nm) and SWIR (1000-2500nm) wavelength ranges can be used to transform a NIR camera with an InGaAs sensor or SWIR camera with an MCT sensor into a line-scan spectral imaging device.

ImSpectors provide easiest integration and highest optical performance for NIR and SWIR ranges on the market.

Fore Optics Available:
