Embodiment 1

[0082] This embodiment provides an optical lens, please refer to figure 1 The schematic diagram of the structure of the optical lens of this embodiment shown in the direction along the optical axis from the object side to the image side includes:

[0083] A diaphragm 10, a first lens 11, a second lens 12, a third lens 13, a fourth lens 14, a fifth lens 15, a filter 16 and an imaging surface 17 having the same central axis;

[0084] Wherein, the aperture 10 is arranged on the object side of the first lens, that is, in front of the aperture, and a larger aperture can be set to increase the light throughput of the optical lens and ensure the brightness of the picture obtained by the optical lens.

[0085] The first lens 11 has a positive refractive power, and the object side of the first lens 11 is a convex surface, which is used to provide a positive refractive power and converge light from the object side. And, the curvature of the convex surface on the object side of the firs...

Embodiment 2

[0124] This embodiment provides an optical lens, please refer to Figure 4 The structural schematic diagram of the optical lens of this embodiment shown is different from the first embodiment in that the optical lens in this embodiment satisfies the relational expressions (1) to (9) in the first embodiment, and the The optical lens also satisfies the relation:

[0125] -0.3

[0126] Wherein, F is the total focal length of the optical lens, and R2 is the radius of curvature of the image side of the first lens. The lens of the optical lens satisfies this relational expression, which is conducive to reducing the total length of the optical lens.

[0127] In this embodiment, the 10 aspheric surfaces of the above five lenses meet the conditions:

[0128]

[0129] Said z represents the Z coordinate value of each point on the lens surface, r represents the Y-axis coordinate value of each point on the lens surface, c is the reciprocal of the curvature radius R of ...

Embodiment 3

[0140] This embodiment provides an optical lens, please refer to Figure 7 The schematic diagram of the structure of the optical lens of this embodiment is shown, wherein, the shape feature of the lens in the optical lens is different from that of Embodiment 1. In addition to the shape feature of the lens in Embodiment 1, this embodiment also has the following feature:

[0141] The image side of the first lens 31 is convex, and the object side of the second lens 32 is convex.

[0142] Through the above arrangement, the viewing angle of the optical lens can be further increased, and the total length of the optical lens can be shortened.

[0143] Moreover, in this embodiment, the difference from Embodiment 1 also includes that the third lens 33 in this embodiment has positive refractive power.

[0144] In addition, in this embodiment, the optical lens satisfies the relational expressions (1)-(7) and relational expression (11) in the first embodiment. In addition, the optical l...

Abstract

The invention provides an optical lens which sequentially comprises an aperture, a first lens body, a second lens body, a third lens body, a fourth lens body, a fifth lens body, a light filter and an imaging face along the optical axis from the object side to the image side. The first lens body has positive focal power, and the object side face of the first lens body is a convex face. The second lens body has negative focal power, and the image side face of the second lens body is a concave face. The object side face of the third lens body is a concave face. The fourth lens body has positive focal power, and the object side face of the fourth lens body is a concave face. The fifth lens body has negative focal power. The object side faces and the image side faces of the first lens body, the second lens body, the third lens body, the fourth lens body and the fifth lens body are all of a non-spherical structure. By matching and adjusting the lens bodies, parameters of the optical lens satisfy the relational expressions that 1<F / F1<1.5, 0<D45 / F<0.1 and 15<F3 / F4<101. The total length of the lens is effectively reduced, and the optical lens can conveniently meet the ultra-thin requirement of intelligent portable electronic devices.

Description

technical field [0001] The present application relates to the field of optical imaging, in particular to an optical lens and an imaging device. Background technique [0002] With the continuous development of science and technology, more and more imaging devices are applied to people's work and daily life, which brings great convenience to people's work and daily life.
