ABSTRACT:
Precise thickness control for high performance optical coatings is provided in an optical coating system utilizing an optical monitor. The optical monitor utilizes a light source and detecting arrangement that measures a sample optical element through the expedient of a light path altering structure that is not coincident with the axis of rotation of a deposition carrousel structure that supports optical elements being coated. The light source and detector arrangements can be mounted conveniently outside of the vacuum chamber of the optical coating system.
