Abstract

The application discloses an optical imaging lens comprising, in order from the object side to the image side along the optical axis, a first lens having a positive focal power, a second lens having anegative focal power, a third lens having a focal power, a fourth lens having a focal power and having an image side as a convex surface, and a fifth lens having a negative focal power and having anobject side as a concave surface, wherein a total effective focal length f of the optical imaging lens satisfies that f is greater than 12mm and less than 20mm.

Description

technical field [0001] The present application relates to an optical imaging lens, in particular to an optical imaging lens including five lenses. Background technique [0002] With the advancement of science and technology, electronic products with camera functions are developing rapidly, and are more and more used in multi-scene cameras in different environments. Among them, electronic products that can be used in long-distance high-definition cameras are more popular in the market. For the camera function of electronic products, the optical imaging lens is the key to determine the camera effect of electronic products. The long focal length lens is very suitable for long-distance shooting because of its small depth of field and easy background blur. Therefore, in order to make an electronic product have a good shooting effect when taking a long-distance camera, the optical imaging lens in the shooting device is required to have a telephoto characteristic. However, the lo...
