Imaging spectrograph
FICS (Fixed Imaging Compact Spectrograph) family of 1/8-m focal length spectrographs are fixed grating units that use a f/2.1 concave holographic grating. Fixed wavelength settings and one-time calibration facilitate integration into OEM instruments. The flat output plane is designed for multichannel PDAs, CCDs, and ICCD detectors.
