Compact high-pixel mobile phone lens

Abstract

The invention provides a compact high-pixel mobile phone lens, which comprises a first lens, a diaphragm, a second lens and a third lens in sequence from an object side to an image side, wherein the first lens is a meniscus lens having positive focal power, the convex surface faces towards the object side, and both sides of the first lens are even-aspheric glass lenses; the second lens is a concave-convex lens having positive focal power, the concave surface faces towards the object side, the convex surface faces towards the image side, and both sides of the second lens are even-aspheric glasslenses; and the third lens is a biconcave lens having negative focal power, and both sides of the third lens are even-aspheric plastic lenses. The compact high-pixel mobile phone lens meets the relation that TTL is greater than or equal to 4.94mm and less than or equal to 6.045mm, wherein TTL refers to the distance from an outmost point at the object side of the first lens to an imaging surface of the compact high-pixel mobile phone lens. The lens provided by the invention has the advantages of compact structure, wide viewing angle, small distortion and high imaging definition.

Description

【Technical field】 [0001] The invention relates to an optical lens, in particular to a compact high-pixel mobile phone lens. 【Background technique】 [0002] In the early days of the birth of cameras for electronic devices such as mobile phones, their pixels were about 300,000, and their image quality was poor, which could not meet the needs of users for high-definition photography. At the same time, they also had the disadvantage of a small field of view. [0003] Therefore, how to meet the requirements of a mobile phone lens with a compact structure, a high-quality imaging effect, and a large field of view is a technical problem to be solved urgently by those skilled in the art. 【Content of invention】 [0004] In order to overcome the deficiencies in the prior art. The invention provides a compact high-pixel mobile phone lens. [0005] The technical solution of the present invention to solve the technical problem is to provide a compact high-pixel mobile phone lens, whic...
