摘要	In order to meet the application requirement of a certain long wavelength infrared (LWIR) seeker, a small volume, light weight and passively athermalized infrared (IR) objective is designed in this paper. The two-lens telephoto structure is adopted by merely using aluminum alloy as the housing material. By balancing the thermo-optical coefficient and thermal expansion coefficient of materials, an athermalized IR seeker with effective focal length of 90 mm and F number of 1.2 is achieved. The whole optical length is 75 mm, and the weight is only 234 g. The objective can remain fine imaging quality under temperature range from 40 C to 60 C, which is beneficial to the lightweight design of IR seekers. 2017, Tianjin University of Technology and Springer-Verlag GmbH Germany.
