Development and testing of a ruggedized compact VNIR-SWIR hyperspectral imager for remote sensing

The Chrisp Compact Visible-SWIR Spectrometer (CCVIS) was developed by MIT Lincoln Laboratory as a high performance, low Size-Weight-Power (SWAP) slit-based hyperspectral sensor that provides comparable performance to current fielded units but more than an order smaller in packaging volume. The design takes advantage of a flat, immersed grating and a color-corrected catadioptric layout to provide >25mm slit length operating from 380-2500nm. We show results from our efforts to design and build an environmentally robust variant which undergoing Technology Readiness Level 6 testing for future spaceflight.
