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.
