About

SPECIM 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.
