2.1.1 Spectrometer
The spectrometer component in each PSR Series spectroradiometer is a crossed
Czerny-Turner configuration using ruled gratings as the dispersive elements. Energy
enters the spectrometer and is collimated before being reflected off the grating s and
refocused onto the PDA detectors. Depending on the model PSR Series instrument,
there are two or three detectors in use. All systems incorporate a 512-element silicon
array covering the spectral range from 350–1000 nm. The PSR-1900 and PSR-2500
contain a single 256-element thermoelectrically-cooled InGaAs array that extends
