Abstract

The invention relates to a four-piece imaging lens group, which comprises an aperture, a first lens having positive refractive power, a second lens having negative refractive power, a third lens having positive refractive power and a fourth lens having negative refractive power in sequence from the object side to the image side. Thus, the invention provides a four-piece imaging lens group which can be applied to portable electronic products, has total lens length which is not too great, and has long focus, high pixel and low lens height.

Description

technical field [0001] The invention relates to a four-piece imaging lens set, in particular to a miniaturized four-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...
