Problems solved by technology

However, the inventors of the present invention have found that during the imaging process, the light incident on the lens assembly from various angles is very likely to form stray light interference in the lens barrel, which has a great impact on the imaging quality. There are measures to reduce light reflection at the light entrance of the imaging lens barrel, but the stray light formed by the light incident into the lens barrel after multiple reflections inside the lens barrel will still reduce the imaging quality

Abstract

The invention relates to the optics imaging technical field, and discloses a light shield, a processing method thereof, and a lens assembly; the light shield is in an annular shape, and comprises an object side surface, an image side surface and a side wall; the light shield is covered by a black powder coating; the light shield can effectively weaken the veiling glare in a lens barrel, thus improving the imaging quality; the invention also discloses the light shield processing method and the lens assembly having the light shield.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a shading plate, a processing method of the shading plate and a lens assembly with the shading plate. Background technique [0002] In recent years, with the development of imaging technology and the rise of electronic products with imaging functions, optical lens components have been widely used in various products, and have been continuously improved and optimized. At present, the improvement direction of most lens components is: how to make the lens component small and thin, and how to select a suitable lens with good optical characteristics while making the lens component small and thin, and study how it Combining them together can ensure a good imaging effect. However, the inventors of the present invention have found that during the imaging process, the light incident on the lens assembly from various angles is very likely to form stray light interference in the le...
