The rise of the metaverse concept has further driven the rapid rise of Augmented Reality (AR) and Virtual Reality (VR) technologies, enabling immersive interaction between people and technological products and enriching daily life with more diverse experiences. In AR / VR products, optical camera lenses play a crucial role in controller positioning, perspective scanning, and gesture recognition. Therefore, developing high-quality optical camera lenses is essential for improving the performance of AR / VR products. For optical camera lenses with a large field of view, the number of lenses and the diameter of the lenses are usually increased to improve image quality, but problems such as poor edge sharpness still exist.

Detailed Implementation

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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 lens or the third lens.

[0060] 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.

[0061] In this paper, the paraxial region refers to the region near the optical axis. If the lens surface is convex and the location of that convexity 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 location of that concaveness is not defined, it means that the lens surface is concave at least in the paraxial region. The determination of the surface shape in the paraxial region can be based on the judgment method commonly used by those knowledgeable in the field, using the R value (R refers to the radius of curvature of the paraxial region, usually the R value in the lens data in optical software) to determine convexity or concavity. For the object side, a positive R value indicates a convex surface, and a negative R value indicates a concave surface; for the image side, a positive R value indicates a concave surface, and a negative R value indicates a convex surface.

[0062] To address the problem of poor edge imaging quality in existing optical camera lenses, this invention provides an optical camera lens.

[0063] Example 1

[0064] like Figures 1 to 22As shown, the optical camera lens includes a lens barrel P0, a first lens to a sixth lens arranged sequentially from the object side to the image side, and a plurality of spacer elements. The first spacer element is located on the image side of the first lens and is at least partially in contact with the image side of the first lens; the second spacer element is located on the image side of the second lens and is at least partially in contact with the image side of the second lens; the third spacer element is located on the image side of the third lens and is at least partially in contact with the image side of the third lens; the fourth spacer element is located on the image side of the fourth lens and is at least partially in contact with the image side of the fourth lens; and the fifth spacer element is located on the image side of the fifth lens and is at least partially in contact with the image side of the fifth lens. The maximum field of view (FOV) of the optical camera lens is greater than 110°. The outer diameter D5s of the object side of the fifth spacer element, the inner diameter d5s of the object side of the fifth spacer element, the effective focal length f of the optical camera lens, and the maximum field of view (FOV) of the optical camera lens satisfy the following relationship: (D5s+d5s) / [f*tan(FOV / 2)]<2.0.

[0065] This invention provides an optical camera lens with a large field of view. By constraining FOV, f, D5s, and d5s within a certain range, it helps to rationally allocate optical power. At the same time, by using the fifth spacer element to control the minimum outer diameter of the sixth lens, the outer diameter of the sixth lens is ensured to be reasonable. Furthermore, by controlling (D5s+d5s) / [f*tan(FOV / 2)] within a reasonable range, while ensuring imaging effect, it can effectively control the size of the lens barrel P0 from the fifth spacer element to the sixth lens, which further helps to ensure the imaging effect at the edge of the large field of view optical camera lens, thereby improving the imaging quality of the optical camera lens.

[0066] The present invention also improves the assembly stability of the fifth lens, the sixth lens, and the spacer element to which they rest by controlling the outer diameter of the sixth lens and the inner and outer diameters of the fifth spacer element.

[0067] Preferably, the outer diameter D5s of the object side of the fifth spacer element, the inner diameter d5s of the object side of the fifth spacer element, the effective focal length f of the optical camera lens, and the maximum field of view FOV of the optical camera lens satisfy the following: 1.73≤(D5s+d5s) / [f*tan(FOV / 2)]≤1.85.

[0068] In this embodiment, the object side surface of the first lens is convex, and the image side surface of the first lens is concave. The following relationship is satisfied among the outer diameter D1s of the object side surface of the first spacer element, the curvature radius R1 of the object side surface of the first lens, the curvature radius R2 of the image side surface of the first lens, and the inner diameter d1s of the object side surface of the first spacer element: 1.0 < D1s / (R1 + R2) + d1s / (R1 - R2) < 5.0. By restricting D1s / (R1 + R2) + d1s / (R1 - R2) within a reasonable range, the difference between the curvature radius R1 of the object side surface of the first lens and the curvature radius R2 of the image side surface of the first lens can be utilized to determine the size of the outer diameter D1s of the object side surface of the first spacer element, and the surface shape parameters of the first lens can also be controlled to ensure the formability of the first lens. Preferably, 2.78 ≤ D1s / (R1 + R2) + d1s / (R1 - R2) ≤ 4.30.

[0069] In this embodiment, the object side surface of the second lens is concave, and the image side surface of the second lens is convex. The following relationship is satisfied among the curvature radius R3 of the object side surface of the second lens, the curvature radius R4 of the image side surface of the second lens, the outer diameter D2s of the object side surface of the second spacer element, and the inner diameter d2s of the object side surface of the second spacer element: |R3 * R4| / {π * [(D2s / 2) 2 - (d2s / 2) 2} < 7.0. By controlling the surface shape of the second lens, the second lens has a converging effect on light. By restricting |R3 * R4| / {π * [(D2s / 2) 2 - (d2s / 2) 2} within a reasonable range, the convergence degree of marginal rays can be effectively controlled by controlling R3 and R4, thereby controlling the size and position of the diaphragm, ensuring the light transmission amount and aperture size of the optical imaging lens, synchronously restricting the outer diameter of the object side surface of the second spacer element can control the outer diameter size of the second lens, ensuring the reasonable distribution of lens sizes, and effectively controlling the uniformity of the overall structure of the optical imaging lens. Preferably, 0.78 ≤ |R3 * R4| / {π * [(D2s / 2) 2 - (d2s / 2) 2} ≤ 6.12.

[0070] In this embodiment, the radius of curvature R4 of the image-side surface of the second lens, the radius of curvature R5 of the object-side surface of the third lens, the inner diameter d2s of the object-side surface of the second spacer element, and the inner diameter d2m of the image-side surface of the second spacer element satisfy the following condition: 0 < (R4 + R5) / (d2s + d2m) < 22.0. By limiting (R4 + R5) / (d2s + d2m) within a reasonable range, and by controlling the radius of curvature of the image-side surface of the second lens and the object-side surface of the third lens, it is beneficial to reduce the sensitivity of the air gap between the second and third lenses and improve the assembly stability. In addition, constraining the inner diameter of the image-side surface of the second spacer element can effectively intercept excess stray light and improve image quality.

In addition, the first lens is preferably a glass lens. Controlling CT1 can ensure the strength of the glass lens and improve the reliability of the optical camera lens. Preferably, 4.11 ≤ (D0s + d0s) / (EP01 + CT1) ≤ 8.28.

[0102] In this embodiment, the sixth lens has a negative optical power, and the following relationship is satisfied among the outer diameter D5m of the image side surface of the fifth spacer element, the inner diameter d5m of the image side surface of the fifth spacer element, and the effective focal length f6 of the sixth lens: -5.0 < f6 / (D5m - d5m) < 0. By restricting f6 / (D5m - d5m) within a reasonable range and simultaneously controlling the sixth lens to have a negative optical power, it can be ensured that the sixth lens diverges light rays and controls the exit angle of the light rays, ensuring that the image plane has a size adapted to the chip. In addition, by adjusting the inner diameter of the image side surface of the fifth spacer element, non-imaging light rays at large angles can be effectively intercepted, improving the imaging quality at the chip edge and ensuring the relative illuminance of the outer field of view. Preferably, -4.82 ≤ f6 / (D5m - d5m) ≤ -1.41.

[0103] Optionally, the above optical camera lens may further include a color filter for correcting color deviation and / or a protective glass for protecting the photosensitive element located on the imaging surface.

[0104] The optical camera lens in this application can adopt multiple lenses, such as the six lenses mentioned above. By reasonably allocating the effective focal lengths, surface shapes, central thicknesses of each lens, and the on-axis distances between each lens, etc., the aperture of the optical camera lens can be effectively increased, the sensitivity of the lens can be reduced, and the processability of the lens can be improved, making the optical camera lens more conducive to production and processing and applicable to portable electronic devices such as smartphones.

[0105] In this application, at least one of the mirror surfaces of each lens is an aspherical mirror surface. The characteristics of an aspherical lens are that the curvature continuously changes from the center of the lens to the periphery of the lens. Different from a spherical lens with a constant curvature from the center of the lens to the periphery of the lens, an aspherical lens has better curvature radius characteristics and has the advantages of improving distortion aberration and astigmatism aberration. After using an aspherical lens, it is possible to eliminate the aberration that appears during imaging as much as possible, thereby improving the imaging quality.

[0106] However, those skilled in the art should understand that without departing from the technical solutions claimed in this application, the number of lenses constituting the optical camera lens can be changed to obtain the various results and advantages described in this specification. For example, although six lenses are described as an example in the embodiment, the optical camera lens is not limited to including six lenses. If necessary, the optical camera lens may also include other numbers of lenses.

[0107] Figure 1 A schematic structural diagram of an optical camera lens of this application is shown. Figure 1 Parameters such as d0s, D3S, D5m, etc. are also marked in it to clearly and intuitively understand the meaning of the parameters. For the convenience of showing the structure of the optical camera lens and the specific surface shape, these parameters will no longer be shown in the subsequent description of specific examples in the drawings.

[0108] Where Dis refers to the outer diameter of the object-side surface of the i-th spacer element, dis refers to the inner diameter of the object-side surface of the i-th spacer element, Dim refers to the outer diameter of the image-side surface of the i-th spacer element, and dim refers to the inner diameter of the image-side surface of the i-th spacer element, where i is a value from 1, 2, 3, 4, and 5. EPij refers to the distance along the optical axis between the image-side surface of the i-th spacer element and the object-side surface of the j-th spacer element, where j > i, and i is a value from 1, 2, 3, and 4, while j is a value from 2, 3, 4, and 5. d0s is the inner diameter of the object-side end face of the lens barrel P0, and D0s is the outer diameter of the object-side end face of the lens barrel P0. The object-side end face of the lens barrel P0 is the surface of the lens barrel P0 closest to the object side, and the image-side end face of the lens barrel P0 is the surface of the lens barrel P0 closest to the image side.

[0109] It should be noted that the maximum thickness CPi of the i-th spacer element refers to the maximum distance along the optical axis from the object side surface of the i-th spacer element to the image side surface of the i-th spacer element.

[0110] The following description, with reference to the accompanying drawings, further illustrates examples of specific surface shapes and parameters of optical camera lenses applicable to the above embodiments.

[0111] It should be noted that the following examples include a first state, a second state, and a third state. In the same example, the curvature radius, center thickness, and other parameters of the individual lenses of the optical camera lens in the first, second, and third states are the same, as are the inter-lens spacing and higher-order image coefficients. However, the parameters such as the lens barrel P0, the thickness of the spacer element, the inner diameter and outer diameter of the spacer element, and the distance between the spacer elements are different, and the shapes of some lenses are also different. In other words, the main structure used for imaging is the same, but the auxiliary structures used for imaging are different.
