Abstract

An optical lens module, which has an optical axis, and the optical lens module includes a first lens element, a second lens element, and a third lens element arranged symmetrically along the optical axis from the object side toward the image side , a fourth lens element, a fifth lens element, a sixth lens element, and an image plane, the first lens element having a positive power, having a first surface and a second surface, the second lens element having a third surface and a fourth surface, the third lens element has a positive power, the third lens element has a fifth surface and a sixth surface, and the fourth lens element has a negative power. The fourth lens element has a seventh surface and an eighth surface, and the fifth lens element has a positive power. The fifth lens element has ninth and tenth surfaces and the sixth lens element has a negative power. The sixth lens element has an eleventh surface and a twelfth surface.

Description

technical field [0001] The invention relates to a lens, in particular to an optical lens module. Background technique [0002] In a camera, a camera captures an object by capturing visible light and finally images the object on a film or screen. The optical lens module directly affects the quality of the imaging and the quality of the imaging effect. [0003] In the prior art, in order to reduce the size of the optical lens module, it is often achieved by reducing the size and number of image sensors. Due to the small size or number of image sensors, the imaging resolution of the camera will be reduced. In order to make the size of the optical lens module smaller and have better imaging resolution, most of them are realized by reducing the size of each pixel. In this way, although the optical lens module ensures a small size and a certain resolution, the imaging aberration of the optical lens module is relatively large, thereby affecting the final imaging quality.
