Paper Abstract

With the advanced of instrument design for space exploration and NIR application, the optical systems working at cold temperature become more and more common. Over the past, many lens system has been used at cryogenic temperature making available a lot of cryogenic material data including CTEs and index of refraction. It is now more accessible than ever to design cryogenic lens system. However making a lens design working at cryogenic temperature is still a challenge. To avoid any problem during operation (mostly at cold temperature), both optical and mechanical designer must work together. This paper gives a modest overview of the most recent progress in this field. It provides the basic knowledge that can be used by both lens and mechanical designers to perform cryogenic optical design with success.
