Abstract

This invention provides an image capturing lens system comprising from object-side to image-side: a positive first lens element; a positive second lens element having a convex object-side surface; a negative third lens element; a positive fourth lens element having a convex image-side surface; and a negative fifth lens element having a concave image-side surface, both of the object-side and image-side surfaces being aspheric, and at least one of the object-side and image-side surfaces having at least one inflection point. Both the first and second lens elements of the image capturing lens system provided by the present invention have positive refractive power, which helps to distribute the positive refractive power needed; therefore, the aberrations and the manufacturing sensitivity are reduced, and the yield rate can be enhanced.

Description

technical field

[0001] The present invention relates to an imaging system mirror group, in particular to an imaging system mirror group applied to portable electronic products. Background technique

[0002] With the gradual thinning of personal electronic products, the internal components of electronic products are required to have a smaller size. Under this trend, the size of photographic lenses is also facing the requirement of miniaturization. In addition to the requirement of miniaturization, because of the progress of semiconductor process technology, the pixel area of ​​the photosensitive element is reduced, and the photographic lens is gradually developing into the field of high pixel. Therefore, the requirements for imaging quality are also increasing.

[0003] Traditional miniaturized photographic lenses mounted on portable electronic products, as shown in US Patent No. 8,169,528, mostly adopt a four-piece lens structure. The prevalence of such high-standard mobil...
