Abstract

The invention relates to a lens eccentricity detecting system used for detecting the the eccentricity of a lens to be detected, wherein, the lens eccentricity detecting system comprises a laser transmitting device, a lens bearing device and an image processing device. The laser transmitting device transmits laser; the lens bearing device moves and fixes the lens to be detected on the optical path of the laser; the image processing device receives the laser passing through the lens to be detected so as to form and display images, and determines the eccentric value of the lens to be detected according to the displayed images. By determining the interfacial eccentric value of the lens to be detected by the generated images, the lens eccentricity detecting system can carry out direct-viewing quality control to the interfacial eccentricity of the lens accurately, with simple operation and without specialized inspectors, and the system can be led to the process of volume production. The invention also provides a lens eccentricity detecting method.

Description

technical field [0001] The invention relates to a lens eccentricity detection system and a detection method thereof. Background technique [0002] At present, while consumers require photographing devices, such as digital cameras and digital video cameras, to have better photographing quality, they also hope that these photographing devices are smaller and thinner. In order to meet this requirement, designers usually use double-sided aspheric lenses to reduce the number of lenses in the lens module when designing the lens modules of these shooting devices, which can make the size of the lens module smaller and thinner. [0003] However, in the process of quality management of double-sided aspheric lenses, it is necessary to perform interplanetary eccentricity detection on these lenses to ensure their imaging quality. At present, special testing equipment and professional inspectors must be used to detect lens eccentricity. The operation is complicated, which is not conduciv...
