Paper Abstract

With many optical systems the method that is used to align the optical system needs to be an integral portion of the system design and not an afterthought. Once all the pieces are in fabrication it may be too late to implement a cost-effective alignment procedure for both prototype and production designs. This is especially true with catadioptric systems where the mirror alignment tends to be very critical as far as system performance is concerned. This paper describes the design and use of an aspheric null mirror for the alignment of a two mirror subsystem to a lens cell. The optical system to be aligned was a six-in. EFL, F/2 system working in the 3-5 micrometers bandpass. It consisted of two aspheric mirrors, one aspheric lens, and two spherical lenses.
