ABSTRACT:
A multiplexed spectrophotometry apparatus, including a rotary multiplexer fitted with a plurality of fiber terminals, a spectrophotometer mounted to the multiplexer and rotatable therewith, and a programmable on-board computer. The spectrophotometer includes precision optics, a charge coupled device (CCD) detector, electronics, and a cooling system, all contained in a compact, streamlined housing that is shaped to promote the radiation of heat from the spectrophotometer and thereby prevent excessive heating during operation of the apparatus. The spectrophotometer is mounted directly to the multiplexer so that any selected terminal can readily be brought into precise, reproducible alignment with the spectrophotometer input. All components of the apparatus are contained in a compact housing adapted for either rack-mounted or bench-top use.
