Abstract

The invention discloses a five-piece type imaging lens group. The five-piece type imaging lens group includes an aperture, a first lens having positive refractive power, a second lens having negativerefractive power, a third lens having negative refractive power, a fourth lens having negative refractive power, and a fifth lens having positive refractive power in an object side to image side order. The invention provides the five-piece type imaging lens group that can be applied to a portable electronic product, cannot make the total length of the lens too long and has a long focal length, a high pixel and a low lens height.

Description

technical field [0001] The invention relates to a five-piece imaging lens set, in particular to a miniaturized five-piece imaging lens set applied to electronic products. Background technique [0002] High-quality small photographic lenses are standard equipment for various mobile devices, and with the progress of semiconductor manufacturing, the pixel area on the electronic photosensitive component is getting smaller and smaller, which in turn requires more fine-grained resolution of the camera lens power, so that more detailed picture quality can be presented. [0003] The miniaturized photographic lenses that are traditionally mounted on portable electronic products mostly adopt a four-piece lens structure. The pixel area is gradually shrinking, and under the condition that the requirements for system imaging quality continue to increase, the known four-element lens group will not be able to meet higher-level photographic lens modules. [0004] Therefore, how to develop...
