Problems solved by technology

Although the imaging quality and resolving power can be improved, the positive refractive power provided by the third lens is smaller than that provided by the first lens, and the distribution of the positive refractive power of the camera lens group cannot be properly dispersed, making it easy for the lens to take pictures. The increased sensitivity of the lens group is not conducive to the production pass rate, so there is a great need for an image capture optical lens group that has both good imaging quality and can easily improve the production pass rate

Abstract

An image capturing optical lens assembly includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element. The first lens element with positive refractive power has a convex object-side surface. The second lens element with negative refractive power has a concave image-side surface. The third lens element with positive refractive power has a convex image-side surface. The fourth lens element has positive refractive power. The fifth lens element with refractive power is made of plastic material and has a concave image-side surface. At least one inflection point is formed on at least one of the object-side and image-side surfaces of the fifth lens element. The surfaces of the third lens element, the fourth lens element and the fifth lens element are aspheric.

Description

technical field [0001] The present invention relates to an image capturing optical lens group, and in particular to an image capturing optical lens group used in imaging applications of electronic products or three-dimensional (3D) imaging applications. Background technique [0002] In recent years, with the rise of portable electronic products with photography functions, the demand for miniaturized imaging lens sets is increasing. The photosensitive element of the general imaging lens group is nothing more than two types of photosensitive coupling device (Charge Coupled Device, CCD) or complementary metal oxide semiconductor device (Complementary Metal-Oxide Semiconductor Sensor, CMOS Sensor), and with the improvement of semiconductor process technology , so that the pixel size of the photosensitive element is reduced, and the miniaturized image lens group is gradually developing into the field of high pixels. Therefore, the requirements for imaging quality are also increas...
