Abstract: A shutter assembly for use with a spectrometer having at least one source of optical radiation such as at least one laser capable of generating an excitation light beam having an illumination path. The shutter assembly includes a shutter having at least one of (i) at least one calibration material capable of generating a consistent spectrum within wavelengths utilizable by the spectrometer and (ii) a mirror capable of diverting at least one of the illumination path and a collection path relative to a calibration standard capable of generating a consistent spectrum within wavelengths utilizable by the spectrometer. The shutter assembly further includes a mechanism capable of moving the shutter into at least a first position in the path of the light beam and a second position out of the path of the light beam to enable a sample to be analyzed. When the shutter is moved into the first position, at least one of (a) the light beam strikes the calibration material as desired yet remains blocked from further travel, (b) the light beam is diverted by the mirror to the calibration standard, and (c) the collection path is diverted by the mirror to communicate with the calibration standard while the illumination path is blocked.
