Overview
The Compact Lyman-alpha Spatial heterodyne Spectrometer (CLASS) is a spectrometer that makes of an interferometric technology called Spatial Heterodyne Spectrometer (SHS) that enables CLASS to obtain ultra-high sensitivity data from angularly extended and diffused targets such as the solar corona. The low-mass, compact configuration of CLASS enables sensitive, high-resolution spectroscopy for SmallSat missions. CLASS is configurable for a variety of spectral lines with a very narrow bandpass anywhere from the FUV to the visible, but for development, CLASS is configured to target the H I Lyα line at 1216 angstrom.
