High sensitivity and low noise are necessary requirements for infrared detection technology, and one of effective means to achieve this goal is the cold optics technology. Correspondingly, cold optics technical maturity further promotes the rapid development of infrared detection. This article reviews relevant literature on typical foreign refrigeration equipment of ground-based large aperture telescope, and briefly describes their cooled infrared instrument. From the perspective of the engineering applications, several elements of the infrared optics were described, such as cryostat production, optical and mechanical design, the detector installation’s key design points and considerations in cold optics processing.
