Compact, Three-Mirror Anastigmat, with 'Reflective Lens'

摘要

A uniquely packaged three-mirror anastigmat (TMA) is discussed. The telescope has 5 major parts, including the optics. This compact TMA exhibits diffraction-limited performance in the MWIR and LWIR wavelength regions and operates at fast F-numbers and relatively wide fields of view. Optical surfaces and critical mechanical interfaces are single-point diamond-turned, allowing for drop-together assembly and alignment. This paper discusses the evolution of the optical/mechanical design, developed under the auspices of the Standard Missile Company and NAVSEA PMS422.
