Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] see Figure 1~3 , In the embodiment of the present invention, there is a meniscus lens with positive refractive power and the concave surface facing the object surface from the object side to the imaging surface, and a filter between the lens and the imaging surface, and the lens is a chalcogenide glass aspheric surface.

[0020] Further: the uncooled long-wave infrared wide-angle lens satisfies a one-piece structure.

[0021] Further: the uncooled lon...

Abstract

The invention discloses a low-cost uncooled long-wave infrared wide-angle lens. The low-cost uncooled long-wave infrared wide-angle lens comprises a meniscus lens and an optical filter from an objectside to an image plane; the meniscus lens has positive focal power; the concave surface of the meniscus lens is towards an object plane; the optical filter is between the lens and an imaging surface;and the lens material is chalcogenide glass. According to the low-cost uncooled long-wave infrared wide-angle lens in the invention, the lens is a chalcogenide glass aspherical lens; therefore, the uncooled long-wave infrared wide-angle lens has better optical performance; and simultaneously, the uncooled long-wave infrared wide-angle lens can be miniaturized.

Description

technical field [0001] The invention relates to the technical field of uncooled infrared thermal imaging lenses, in particular to a low-cost uncooled long-wave infrared wide-angle lens. Background technique [0002] Since uncooled long-wave infrared products are high-end industrial temperature detection and monitoring products, both detectors and infrared lenses have always been expensive, which is not conducive to popularization and consumerization. Now Ulis in France has launched the Micro80P detector, and Flir in the United States has launched the smaller Lepton consumer-grade detector. The price has dropped and the size is small, which provides conditions for the rapid consumerization of uncooled infrared products. Some manufacturers are now building uncooled infrared products into mobile phones. [0003] Traditional spherical infrared lenses cannot achieve a one-piece optical structure, and are bulky and costly, making it difficult to quickly consume them. Contents o...
