The short wave infrared spectrograph designed for the SWIR (1000 - 2500 nm) wavelength range can be used to transform a SWIR camera with a wide spectral range sensor, such as a cooled mercury-cadmium-telluride (MCT) sensor, into a line-scan hyperspectral imaging device. In the SWIR range, this spectrograph offers the highest optical performance on the market, by reducing keystone and smile aberrations to sub-pixel levels.
