A restricted and folded space envelope and the requirement to operate in focus without adjustment over a wide temperature range often leads to an optical system whose design departs significantly from the classical constructions. The design of a folded, passively athermalised 250mm F/2.5 vidicon lens is described, highlighting how the space and environmental constraints strongly governed the form of lens design. Two methods of built in test equipment injection are described.
