Problems solved by technology

However, in order to achieve the above technology, the existing lens has a small imaging field of view and cannot completely obtain the overall structure of the test object. In addition, the inaccurate concentricity, precision and axial position also affect the implementation of the compensation technology.

Abstract

The invention relates to an ingenious hand regulation type long-wave infrared-optical heat-free temperature measuring lens which is applicable to the field of optical lens units. The ingenious hand regulation type long-wave infrared-optical heat-free temperature measuring lens comprises a main lens cone, a negative crescent lens and a biconvex lens are sequentially arranged in the main lens cone along the incidence direction of light, a front compression ring is arranged at the position of the front side of the negative crescent lens in the main lens cone, a space ring is arranged between the negative crescent lens and the biconvex lens, and a connecting seat is further arranged at the rear portion of the main lens cone. The temperature measuring lens is not only simple in structure but also convenient in use.

Description

technical field [0001] The invention relates to a smart hand-adjustable long-wave infrared optical athermalization temperature measuring lens, which is suitable for the field of optical lens devices. Background technique [0002] As a non-contact temperature measurement technology, infrared temperature measurement technology has many advantages compared with traditional temperature measurement technology, making infrared temperature measurement technology widely used in power industry, aerospace, quality inspection, metallurgy and other fields. Wen lens came into being. Since infrared optical materials and mechanical materials will produce thermal deformation when the temperature changes, drastic changes in operating temperature will cause changes in the focal length of the optical system, image surface drift, and image quality degradation. In order to eliminate or reduce the impact of temperature changes on the imaging of the optical system, corresponding compensation tech...
