Structure for rapid adjustment of coaxiality of lens

Abstract

The invention discloses a structure for rapid adjustment of the coaxiality of a lens. The structure comprises a lens mount, the lens mount is connected with a rear cover, the rear cover is connected with an aligning group capable of moving on a horizontal plane thereof, the aligning group comprises a lens frame and a lens group arranged on the lens frame, the rear cover is provided with a throughhole, a step used for placing the aligning group is arranged in the through hole, and the inner diameter of the through hole is greater than the external diameter of the lens frame so that the aligning group has displacement on the plane in which the rear cover is located and the coaxiality of the lens group and other groups is adjusted. According to the structure, the coaxiality relative to othergroups can be adjusted through adjustment of the position of the aligning group, the increasingly improved optical specification and requirement can be realized, the optical design performance is finally realized, defects of conventional production and product technologies are overcome, the improvement of the optical design difficulty can be assisted, sensitive items are integrated to a certain position for design, and the overall performance of the product design is finally improved.

Description

[0001] 【Technical field】 [0002] The invention relates to a structure for quickly adjusting the coaxiality of a lens. [0003] 【Background technique】 [0004] With the rapid development of high technology, security optical zoom lens has been widely used. In order to meet the needs of the market, more and more lenses need to use high-resolution large chips, and zoom lenses must also be used in different fields and environments, making lens design more and more difficult, and the technical requirements of each group are getting higher and higher. The higher the level, the higher the requirements for product molding and process manufacturing. Under the premise of existing manufacturing technology, it is difficult to achieve the initial requirements of optical design, and it is even more difficult to achieve the expected production yield, so that it cannot meet high-speed The increased market demand will eventually make it difficult to maintain the industry leader.
