Problems solved by technology

However, in order to achieve a better telephoto shooting effect, the number of lenses in the optical lens increases, and the thickness of the lenses also increases, so that the thickness of the optical lens increases
The thickness of the optical lens is often the main factor limiting the development of terminal thinning. Therefore, how to reduce the thickness of the optical lens while achieving the telephoto effect of the optical lens has become a hot research issue.

Embodiment Construction

[0107] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0108] For the convenience of understanding, the technical terms involved in this application are firstly explained and described below.

[0109] Focal length (focal length), also known as focal length, is a measure of the concentration or divergence of light in an optical system. The vertical distance from the optical center to the imaging plane. For a fixed-focus lens, the position of its optical center is fixed; for a zoom lens, a change in the optical center of the lens brings about a change in the focal length of the lens.

[0110] Aperture is a device used to control the amount of light passing through the lens and entering the photosensitive surface of the camera body, which is usually inside the lens. The aperture size is expressed in F / number.

[0111] The aperture F value is the relative value obtained from the focal l...

Abstract

The invention provides an optical lens, a lens module and a terminal. The optical lens sequentially comprises a first component, a second component, a third component and a fourth component from an object side to an image side, wherein each component comprises at least one lens. The optical lens satisfies the following relational expressions: 9.08 < = BFL < = 11.745, and 0.6 < = BFL / TTL < = 0.67, so that the optical lens can obtain a relatively large back focal length BFL, and realize long-focus shooting. Moreover, the thickness TTL1 of a plurality of lens elements of the optical lens on the axis is relatively small, so that the terminal comprising the optical lens can be relatively thin.

Description

technical field [0001] The embodiments of the present application relate to the lens field, and in particular to an optical lens, a lens module, and a terminal. Background technique [0002] At present, in order to be suitable for shooting in various scenarios, different optical lenses are generally equipped in the terminal to realize the use in different scenarios. For example, some terminals are configured with a telephoto lens to achieve telephoto shooting. However, in order to achieve a better telephoto shooting effect, the number of lenses in the optical lens increases, and the thickness of the lenses also increases, so that the thickness of the optical lens increases. The thickness of the optical lens is often the main factor limiting the development of terminal thinning. Therefore, how to reduce the thickness of the optical lens while achieving the telephoto effect of the optical lens has become a hot research issue. Contents of the invention [0003] Embodiments ...
