ABSTRACT:
An interferometer having two spaced apart but parallel composite beams passing through respective fluid containing cells with the radiation output of these cells being imaged onto a detector. The optics at one end of the cells are made movable with respect to the optics at the other end of the cells in order to accommodate various size cells and materials, and to simplify optical alignment of the interferometer without disturbing the focusing properties of the instrument.
