The INT10-M Monolithic Michelson Interferometer, for designers knowledgeable in the field. Using PLX's Monolithic Optical Structure TechnologyTM (MOSTTM).

The unit is permanently aligned and fused with the two arm mirrors imaged onto each other by a beamsplitter-compensator in a monolithic assembly. A moving retroreflector is added to one arm to complete the interferometer and allow for the variation of the optical path difference around zero OPD. The INT10-M Monolithic Michaelson Interferometer is especially suited for those with experience in FTIR machine architecture who wish to incorporate it in their proprietary designs.
