The INT05-N Monolithic Michelson Interferometer is offered for companies wishing to construct proprietary NIR Fourier Transform Spectroscopy analyzers.

The unit is permanently aligned and fused with the two arm mirrors imaged onto each other by a beamsplitter-compensator in a monolithic assembly. The unit is extremely rugged and never needs adjustment. 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 rugged construction and permanent alignment make the INT05-Series NIR interferometers suitable for your most demanding NIR analyzer applications.
