It can be seen from the figure that the maximum equivalent temperature difference of cold reflection is 17.3 mK, which is less than the system NETD, and cold reflection meets the requirements of use.
The super field of view infrared optical lens, whose field of view is generally above 90°, is mainly used in the military to warn and indicate incoming missiles or infrared threat targets. It is an important military optoelectronic product. Compared with conventional infrared optics, the super field of view infrared optical lens
has many different characteristics. The specific design examples are given in the article, which has a certain guiding significance for the design of this type of optical system.
