Abstract

The invention relates to a portable long wave infrared temperature measuring lens and a working method thereof. The optical system of the lens is successively provided with a negative crescent-shaped lens A, a positive crescent-shaped lens B, and a positive crescent-shaped lens C along the light incident direction, the air interval between the negative crescent-shaped lens and the positive crescent-shaped lens B is 22mm, and the air interval between the positive crescent-shaped lens B and the positive crescent-shaped lens C is 4mm. The portable long wave infrared temperature measuring lens has the advantages of large relative aperture, low distortion, manual adjustment, and economical and practical use; the optical axis stable imaging is more clearly and high in reliability due to the manual adjustment, and users' requirement on the imaging performance of products can be met, and the structure allows the users to use conveniently.

Description

technical field [0001] The invention relates to a portable long-wave infrared temperature measuring lens and a working method thereof, belonging to the technical 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. First, its measurement does not interfere with the temperature measurement field, does not affect the temperature distribution, and has high accuracy and precision; secondly, Infrared temperature measurement is fast and can be observed in real time, which has great advantages in measurement; thirdly, infrared temperature measurement can be near or far, and can work at night, with strong adaptability; finally, infrared temperature measurement has a wide range and theoretically has no upper limit for testing. This makes infrared temperature measurement technology widely used in powe...
