Abstract

The invention discloses an optical imaging lens. The optical imaging lens sequentially comprises the following lens from an object side to an image side along an optical axis: a first lens with focal power, wherein the object side surface is a convex surface; a second lens with focal power; a third lens positive focal power; and a fourth lens with focal power, wherein the object side surface of the fourth lens is a concave surface. A half Semi-FOV of the maximum field angle of the optical imaging lens meets the condition that Semi-FOV is greater than 10 degrees and smaller than 25 degrees; and the distance TOL between the shot object and the object side surface of the first lens on the optical axis meets the following condition: 2.0 mm < TOL < 32.0 mm.

Description

technical field [0001] The present application relates to the field of optical elements, in particular, to an optical imaging lens. Background technique [0002] With the rapid development of portable electronic products such as smart phones, consumers are using more and more shooting functions of smart phones, and have higher and higher requirements for the imaging quality of mobile phone lenses under different conditions. However, most of the camera lenses of smartphones currently on the market are difficult to clearly image tiny details, and it is difficult to reflect the details of objects. Contents of the invention [0003] The present application provides such an optical imaging lens in one aspect. The optical imaging lens includes in sequence from the object side to the image side along the optical axis: a first lens with a focal power, the object side of which is a convex surface; a second lens having a positive power; and a fourth lens having a power whose object...
