Abstract
The present invention is a multiplexer for use with an apparatus for optically analyzing a sample. This multiplexer includes a body portion having a primary inlet port. The light received through the light inlet port is sent through a first fiber optic bundle which may be rotated by a fiber carriage to any of several outlet fiber couplers which may be connected to various samples. A position optical sensor assures proper alignment between the first fiber optic bundle and the fiber couplers by sensing the position of a chopper disc which is mounted to the rotating fiber carriage. Once light is passed through the sample, it is passed back into the multiplexer through inlet fiber couplers. These additional fiber couplers are linked to a second fiber optic bundle leading to a detector fiber coupler which may be connected to a fixed fiber cable.
