description The invention relates to an infrared cold optical lens structure adopting a self-adaptive flexible supporting structure, and aims to solve the problem that in the prior art, an optical element of a low-temperature infrared lens system violently deforms under the huge temperature difference of machining, assembling and actual working environments cannot be effectively and conveniently solved. And the requirements of high surface shape precision and low deformation stress of a cold optical ray machine system are difficult to realize, so that the imaging quality is directly influenced. The structure comprises a low-temperature infrared lens, a lens supporting frame and M mounting positioning pins, the lens supporting frame is an integrated piece and comprises a lens frame rigid body and N external connection flexible seats. The N external connection flexible seats are fixedly connected to the outer wall of the mirror frame rigid body; m arc-shaped grooves which are through in the radial direction are formed in t
