Scientific paper

The advantages inherent in precision diamond-machined optics are discussed, with respect to the high-accuracy reference of optical surfaces to both axes of a Ritchey-Chretien IR telescope and its auxiliary surfaces. The sample telescope demonstrates cost savings in assembly, alignment time and fine adjustment. Among the topics discussed are: (1) axial relationships; (2) transfer surface relationships; (3) IR telescope specifications; and (4) machining fixture characteristics.
