Description

Technical Field

This is especially true with the explosive growth of the AR / VR industry, leading to the increasing use of wide-angle optical camera lenses. However, existing wide-angle optical camera lenses suffer from significant aberrations, failing to meet the demands for high image quality. Furthermore, the lens manufacturing process for wide-angle lenses is more complex, and their larger size makes them difficult to mount in miniaturized devices. Additionally, the image quality of these lenses is unstable under varying external temperatures, failing to meet users' needs for wide-angle, miniaturized lenses with excellent temperature performance and high image quality.

[0060] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0061] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0062] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0063] It should be noted that in this specification, the terms "first," "second," "third," etc., are used only to distinguish one feature from another and do not imply any limitation on the features. Therefore, without departing from the teachings of this application, the first lens discussed below may also be referred to as the second or third lens.

[0064] In the accompanying drawings, the thickness, size, and shape of the lenses have been slightly exaggerated for ease of illustration. Specifically, the shapes of the spherical or aspherical surfaces shown in the drawings are illustrated by way of example. That is, the shapes of the spherical or aspherical surfaces are not limited to those shown in the drawings. The drawings are for illustrative purposes only and are not drawn strictly to scale.

[0065] In this text, the paraxial region refers to the region near the optical axis. If the lens surface is convex and the position of the convex surface is not defined, it means that the lens surface is convex at least in the paraxial region; if the lens surface is concave and the position of the concave surface is not defined, it means that the lens surface is concave at least in the paraxial region. The surface of each lens closer to the object side is the object side surface of the lens, and the surface of each lens closer to the image side is called the image side surface of the lens. The judgment of the surface shape in the paraxial region can be based on the judgment method of those with ordinary knowledge in this field, and the positive or negative of the R value (R refers to the radius of curvature of the paraxial region, usually the R value on the lens database (lens data) in optical software) is used to judge the convexity and concavity. For the object side surface, when the R value is positive, it is judged as convex, and when the R value is negative, it is judged as concave; for the image side surface, when the R value is positive, it is judged as concave, and when the R value is negative, it is judged as convex.

[0066] In order to solve at least one of the problems of poor imaging quality, poor temperature performance, and difficulty in miniaturization in the prior art, the present invention provides an optical imaging lens.

At the same time, with the refractive index of the first lens and the air gap between the first lens and the second lens on the optical axis, it is beneficial to the processing and forming of the lens, and also beneficial to reducing the length of the front end of the lens. Combining the control of the central thicknesses of the second lens and the fifth lens is beneficial to controlling the total length of the lens, thereby achieving miniaturization.

Preferably, -14.83mm -1 ≤ V1 / f1 ≤ -7.15mm -1 .

[0072] In this embodiment, the distance TTL on the optical axis from the object side of the first lens to the imaging surface of the optical imaging lens and the effective focal length f of the optical imaging lens satisfy: 2.0 < TTL / f < 2.4. By restricting TTL / f within a reasonable range, while ensuring the imaging quality, the length of the optical imaging lens can be shortened, the usage space of the lens can be reduced, and miniaturization can be achieved.
