Abstract
Described are a shutter assembly, a spectrometer, and a method for calibrating a spectrometer. For example, the method may include positioning a shutter including a mirror into a first position in an illumination path of an excitation light beam such that a measurement window is blocked. The mirror may be operable to direct at least one of: (1) the illumination path to a spectral calibration material, (2) a first collection path extending from the spectral calibration material, and (3) a second collection path of a spectral calibration light beam. The method may include directing a returned light from the receiving optics unit to an imaging device; processing the returned light at the imaging device into one or more image signals; analyzing and comparing the image signals with approved image signals; and providing an indication of whether the comparative results of the analysis are within acceptable tolerances.
