Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0033] In addition, it should be noted that the orientation terms such as left, right, up, and down in the embodiments of the present invention are only relative concepts or refer to the normal use state of the product, and...

Abstract

The invention discloses an optical lens for spaceflight, which comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a diaphragm, a seventh lens, an eighth lens, a ninth lens and a tenth lens which are sequentially arranged from an object side to an image side. The first lens and the second lens are both negative meniscus lenses protruding towards the object side. The third lens is a negative meniscus lens protruding towards the image space or a biconcave lens, the fourth lens is a positive meniscus lens protruding towards the image space, the fifth lens is a positive meniscus lens protruding towards the object space or a plano-convex lens or a biconvex lens, the sixth lens is a positive meniscus lens protruding towards the object space, the seventh lens is a biconvex lens, the eighth lens is a plano-concave lens or a biconcave lens, the ninth lens is a biconvex lens, the tenth lens is a biconvex lens, all the lenses are not glued, and the first lens and the tenth lens are single-sided aspheric lenses, so that the optical lens disclosed by the invention can realize large field of view, low distortion and athermalization.

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...
