Lens, camera lens and image device

Abstract

The invention relates to a lens, a camera lens and an image device. The lens comprises an optical part (1) and a fixing part (2) which surrounds the optical part (1) and is connected with the opticalpart (1), the optical part (1) is made of transparent materials, and the fixing part (2) is made of ray adsorption materials. The lens can effectively eliminate stray light and improve imaging quality, the use amount of light isolation sheets can be reduced when the lens is assembled to the camera lens so as to be favorable for reducing the accumulation assemblage errors of the camera lens, imaging quality is further improved, meanwhile, the lengths of a lens cone can be reduced, and the volume of the lens is reduced.

Description

technical field [0001] The invention belongs to the technical field of optical imaging, and in particular relates to a lens, a lens including the lens, and an imaging device including the lens. Background technique [0002] At present, with the rapid development of portable devices, the imaging devices loaded on the portable devices are also rapidly updated. The market has more and more stringent requirements for the imaging effect of this kind of equipment. High imaging quality has gradually become one of the important criteria for the quality of a lens. At the same time, the miniaturization of the lens structure is also one of the development directions of the industry. [0003] Optical lenses usually include an effective diameter part and a non-effective diameter part. When the existing optical lens is assembled into the lens module, the non-effective diameter part will cause reflection and diffuse reflection of the incident light, which will cause noise in the imaging ...

AI Technical Summary

Problems solved by technology

[0003] Optical lenses usually include an effective diameter part and a non-effective diameter part. When the existing optical lens is assembled into the lens module, the non-effective diameter part will cause reflection and diffuse reflection of the incident light, which will cause noise in the imaging system. Astigmatism, which affects image quality

The usual practice of existing lenses is: when assembling the optical lens into the lens barrel, use light barriers and other structures to eliminate the impact on the optical system. However, the method of setting light barriers needs to meet relatively strict assembly conditions. Limited light blocking effect

[0004] In addition, the practice of setting light barriers makes it difficult to guarantee the cumulative assembly error of the lens, which will also affect the image quality

At the same time, due to the installation of multiple light barriers and light barrier components, it is not conducive to the development of the lens towards the trend of miniaturization
