[0023] The present invention adopts the mechanical passive heat dissipation, that is, the structure reverse compensation form, adopts a temperature compensation cylinder, fixes the infrared lens as a whole in the temperature compensation cylinder with screws, and uses the screws and the infrared thermal imager installation frame together with the temperature compensation cylinder The connection surface on the connection. Since the infrared thermal imager is fixed inside the metal with low expansion coefficient, the change of its focal plane position is very small and negligible. The axial movement of the infrared optical system image plane position is realized by relying on the axial movement caused by the temperature change of the temperature compensation cylinder. compensate.
[0024] The traditionally applied mechanical passive heat dissipation design is to install one or several groups of lenses that need to be moved on the guide rail, and connect them to the shell through...
