Problems solved by technology

[0002] At present, the imaging function requirements of portable electronic devices are getting higher and higher, and because portable electronic devices are expected to have a smaller size, the size of the optical imaging lens set on them is also limited
[0003] For example, the mobile phone industry tends to adopt multiple optical imaging lenses for multi-camera. The optical characteristics of the multiple optical imaging lenses are highlighted, which usually includes a telephoto lens with a long focal length. Due to the limitation of the thickness of the mobile phone, the telephoto The optical characteristics of the lens are limited, which limits the imaging effects of mobile phones such as background blur and object magnification.

Abstract

The invention provides an optical imaging lens. The optical imaging lens comprises a prism that is configured such that light entering the prism along the direction of an X optical axis is emitted from the prism along the direction of a Y optical axis after being reflected, wherein the X optical axis is vertical to the Y optical axis. The optical imaging lens comprises the following components along the Y optical axis from the prism to an image side: a first lens having the positive focal power, wherein the object side surface of the first lens is a convex surface; a second lens having the negative focal power, wherein the object side surface of the second lens is a concave surface; a third lens with the focal power, wherein the object side surface of the third lens is a convex surface; afourth lens with the focal power, wherein the object side surface of the fourth lens is a concave surface and the image side surface is a convex surface; and a fifth lens with the focal power. The center thickness CT1 of the prism on the optical axis and the center thickness CT2 of the first lens on the optical axis satisfy that CT2/CT1 is greater than 1.0 but less than 2.0.

Description

technical field [0001] The present application relates to an optical imaging lens, in particular to an optical imaging lens including a prism and five lenses with optical power. Background technique [0002] At present, the imaging function of the portable electronic device is required to be higher and higher, and since the portable electronic device is expected to have a smaller size, the size of the optical imaging lens provided on the portable electronic device is also limited.
