Optical imaging lens

Abstract

The invention discloses an optical imaging lens, which sequentially comprises a first lens with focal power, a second lens with focal power, a third lens with focal power, a fourth lens with negative focal power; a fifth lens with focal power, and a sixth lens with focal power along the optical axis from an object side to an image side, wherein the object side surface of the third lens is a concave surface, the half Semi-FOV of the maximum field angle of the optical imaging lens meets the condition that Semi-FOV is greater than or equal to 60 degrees, the curvature radius R5 of the object side surface of the third lens and the curvature radius R9 of the object side surface of the fifth lens meet the following condition that R5 / R9 is more than 3.5 and less than 11.5, and the curvature radius R9 of the object side surface of the fifth lens and the effective focal length f5 of the fifth lens meet the condition that R9 / f5 is more than -4.0 and less than or equal to -1.5.

Description

technical field

[0001] The present application relates to the field of optical elements, in particular, to an optical imaging lens. Background technique

[0002] In today's life, portable electronic products such as smart phones are not only a communication device, but also a facility for people's daily entertainment. Among them, the camera capability of portable electronic products such as smart phones is one of the important functions that people pay attention to.

[0003] With the development of science and technology, the professionalism of taking pictures of portable electronic products such as smart phones is also gradually improving. Although ordinary standard lenses can produce clear images in most cases, when shooting vast scenes such as tall buildings or mountains, standard lenses can only capture a part of the scene, and cannot show the magnificence and majesty of the scene.
