Abstract

The invention discloses an infrared optical system and an infrared lens, and relates to the technical field of infrared lenses. The infrared optical system comprises a first meniscus positive lens, a second meniscus positive lens, a third meniscus positive lens, a fourth meniscus positive lens, a fifth meniscus positive lens, a sixth meniscus positive lens, a biconcave negative lens and a biconvex positive lens which are sequentially arranged along an optical axis. The infrared optical system further comprises an object side and an image side. The side, away from the object side, of the third positive meniscus lens is provided with a first diffraction surface, and the side, close to the image side, of the sixth positive meniscus lens is provided with a second diffraction surface. According to the infrared optical system provided by the invention, the athermalization effect of the optical system can be realized, and the imaging effect is improved.

Description
