Abstract: An interference spectrometer in which a wedge-shaped prism (32) is moved across one arm (22) of an interferometer for variation of the path difference, and where the beam splitter substrate (36) and prism (32) are optically compensated for by elements substantially identical to the substrate and prism (38, 40) in the other arm of the interferometer. In a first embodiment two refractive elements are in each arm of the interferometer (40, 36, 38, 32). In the preferred embodiment, only one prism is used in each arm, (46, 44) with the beam splitter surface (12) being located on a fixed prism (46), in one arm, adjacent a movable prism (44) in the other arm.
