Abstract
The Compact Wide Swath Imaging Spectrometer (CWIS) is a pushbroom imaging spectrometer for the solar reflected spectrum (380-2500 nm) with wide swath (1600 elements), fast optical speed (F/1.8), and high uniformity (≥95%). The CWIS compact Dyson demonstrates a reduction in volume and mass over the equivalent Offner-type instrument. CWIS is currently under development at the Jet Propulsion Laboratory and is intended to address the need for high signal to noise ratio compact imaging spectrometer systems for the visible short wave infrared wavelength range. Optical design, stray light modeling, and current status of the instrument are discussed.
