Optical lens mechanism

Abstract

The invention relates to an optical lens mechanism. The optical lens mechanism comprises an optical lens, a light shading sheet and a sensor, wherein the light shielding sheet is arranged in the optical lens and is provided with a run-through hole; the sensor is arranged at an imaging position; and at least one light beam entering into the optical lens passes through the run-through hole and is directly projected to the sensor, or does not pass through the run-through hole and is blocked by the light shading sheet.

Description

technical field [0001] The invention relates to an optical lens mechanism, in particular to an optical lens mechanism applied to a photography device. Background technique [0002] The optical lens mechanism is widely used in various photographic devices. The optical lens mechanism usually includes an image sensor and an optical system composed of lenses. The image of the object to be photographed is imaged on the image sensor through an optically designed optical path. When external light beams are projected onto the image sensor through a path other than the optical path of the above-mentioned optical design, light leakage will be caused, thereby affecting image quality. [0003] Conventional optical lens mechanisms usually have complex and precise structures, so as to avoid the above-mentioned light leakage. However, the above-mentioned complicated and precise structure usually causes disadvantages such as low yield rate in the manufacturing process, difficulty in assemb...
