Abstract
A Michelson interferometer has transversely arranged arms defining first and second transverse optical axes of the interferometer. The interferometer includes a beamsplitter for receiving an incoming ray, and transmitting an output ray. The beamsplitter is configured as an optical wedge. The first optical axis is terminated by a first cube corner retro-reflector, and the second optical axis is terminated by a second cube corner retro-reflector. The first and second cube corner retro-reflectors provide self compensation for chromatic aberration and anamorphism between the incoming ray and the output ray, and the transversely arranged arms are free-of any compensator.
