Optical lens for aerospace

Abstract

The invention discloses an optical lens for aerospace, comprising a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a diaphragm and a seventh lens arranged in sequence from the object side to the image side , the eighth lens, the ninth lens, the tenth lens, the first lens and the second lens are both negative meniscus lenses convex to the object side, the third lens is a negative meniscus lens or biconcave lens convex to the image side, the first lens The fourth lens is a positive meniscus lens convex to the image side, the fifth lens is a positive meniscus lens or plano-convex lens or biconvex lens convex to the object side, the sixth lens is a positive meniscus lens convex to the object side, and the seventh lens It is a double-convex lens, the eighth lens is a plano-concave lens or a double-concave lens, the ninth lens is a double-convex lens, and the tenth lens is a double-convex lens. The optical lens disclosed by the invention can realize large field of view, low distortion and adiabatic difference.

Description

technical field [0001] The invention relates to the technical field of optical design, in particular to an optical lens for aerospace. Background technique [0002] With the development of the aerospace industry to a higher level, for special space activities such as extravehicular activities of astronauts and spacecraft flight environments, it is necessary to install a camera device that can work in the outer space environment, and the optical system of the camera device must not only have In addition to the characteristics of large field of view and low distortion, it is also necessary to ensure that its imaging performance can remain stable under conditions such as aircraft landing, drastic temperature changes, and high-flux cosmic radiation. Impact resistance, temperature stability, radiation resistance, large field of view, and low distortion optical lenses for aerospace are necessary. [0003] The existing wide-angle optical system mostly adopts a multi-lens refractio...
