Split lens and camera module

Abstract

The invention relates to a split lens, which comprises an independent object side group forming a free end of the split lens, at least one independent image side group and a diaphragm, wherein the independent image side groups and the independent object side group are sequentially arranged and fixedly connected; and a fit clearance is formed between the object side group and the image side groups. According to the split lens, alignment is freer and more flexible, assembly is convenient and fast and the coordinating precision is high.

Description

technical field [0001] The invention relates to a split lens and a camera module comprising the split lens. Background technique [0002] The lens groups of the existing split lenses do not have matching gaps and specific structural fits, so the upper lens group cannot be accurately adjusted relative to the lower lens group, and the matching accuracy of the upper and lower lens groups is low. This also leads to a low yield rate of the split lens, and the image quality is not good enough. [0003] At this stage, the requirements for high-end video lenses are getting higher and higher. In order to improve the yield rate of the module process and shorten the auto-focus time, research on new process technology has become the direction of everyone's efforts. [0004] Conventional high-pixel module solutions use module alignment technology to improve quality through the correction of the entire image lens. Such alignment methods have low accuracy, large assembly errors in camera ...
