Abstract
This paper introduces the infrared optical system in the Tokamak fusion reaction device. In this optical system, the traditional optical structure can't meet the requirements, because the length of the infrared optical system in the Tokamak is very long. The design of optical system in the detection facility includes three parts:1.the combination of the concave aspheric mirror and flat mirror; 2.the Cassegrain system; 3.the relay group lenses. This paper describes the decrease of the modulation transfer function (MTF) when the temperature changes and how to compensate the decrease of the MTF in order to maintain the image quality in a high level. As a result, the image quality of this optical system can reach the requirements when the temperature changes.
