In the process of athermal design of the infrared optical system, the following issues should be paid attention to. (1) With the change of temperature, the original aberration compensation relationship is destroyed, and the best focus position of the system may change nonlinearly with the change of temperature. (2) For the reflect...

Infrared optical systems often work in environments with a relatively large temperature range. The thermal expansion coefficient of optical materials and mechanical materials and the change in refractive index of optical materials with temperature will seriously affect the performance of the optical system. Compared with optical ma...

The total radiation emitted by the target in the mid-wave infrared and long-wave infrared bands can be obtained by integrating the Planck formula. At different temperatures of the target, the total infrared radiation in the medium-wave and long-wave bands is shown in the left figure below; the ratio of the total infrared radiati...

The answer is not necessarily.It can be understood that the resolution of the human eye is limited, too high-resolution microdisplays such as UHD cannot improve the effect much, and the 4μm pixel almost matches the human eye.Quanhom GE25 supports screen size of 0.61 inches and a pixel size of 4μm. In general, an SVGA re...
