Description

Technical Field

[0001] The present invention relates to the field of optical technology, and in particular to a camera optical lens. Background Technology

[0002] With the rapid development and widespread adoption of smartphones, the research and design of cameras have also advanced rapidly. Furthermore, the current trend in electronic products is towards high functionality and a slim, lightweight design, making miniaturized cameras with excellent image quality the mainstream in the market. Among these, internally focused cameras, due to their high stability, rapid zoom, easy cleaning, and ability to overcome the wear and tear of externally focused cameras, are gradually being developed and applied to mobile phone cameras.

[0054] Please see Figure 1a , Figure 1b , Figure 5a , Figure 5b , Figure 9a , Figure 9b , Figure 13a , Figure 13b , Figure 17a , Figure 17b , Figure 21a , Figure 21b , Figure 25a , Figure 25b , Figure 29a and Figure 29bThe present invention provides a camera optical lens 10, 20, 30, 40, 50, 60, 70, 80, which is composed of a first prism P1, a first lens L1, a second lens L2 with positive refractive power, a third lens L3 with negative refractive power, a fourth lens L4 with positive refractive power, and a fifth lens L5 arranged sequentially from the object side to the image side; a reflecting surface is provided between the object side and the image side of the first prism P1; the first lens L1, the second lens L2, the third lens L3, and the fourth lens L5 are also included. 4 is the first lens group, and the fifth lens L5 is the second lens group. The first lens group is adjustable and movable along the optical axis of the camera lenses 10, 20, 30, 40, 50, 60, 70, and 80, so that the camera lenses 10, 20, 30, 40, 50, 60, 70, and 80 can switch between a first state and a second state. In the first state, the camera lenses 10, 20, 30, 40, 50, 60, 70, and 80 have the largest focal length, and in the second state, the camera lenses 10, 20, 30, 40, 50, 60, 70, and 80 have the smallest focal length.

[0055] The focal length of the camera optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 in the first state is fA; the image height of the camera optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 is IH; the total optical length of the camera optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 is TTL; the radius of curvature of the object-side surface of the first prism P1 is Rp1; the radius of curvature of the image-side surface of the first prism P1 is Rp2; and the... Lens L1 has a focal length of f1 and an on-axis thickness of d1. Lens L4 has a focal length of f4 and an image-side radius of curvature of R8. Lens L5 has a focal length of f5 and an object-side radius of curvature of R9. The on-axis distance from the image-side of lens L5 to the imaging planes of the imaging lenses 10, 20, 30, 40, 50, 60, 70, and 80° in the first state is BF, and the following relationship is satisfied:

[0056] 4.00≤fA / IH≤5.10(1)

[0057] -4.00≤Rp1 / Rp2≤0.71(2)

[0058] -24.00≤f1 / d1≤2.60(3)

[0059] 0.12≤BF / TTL≤0.35(4)

[0060] 0.20≤f4 / R8-f5 / R9≤4.30(5)

[0061] Among them, camera optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 are periscope optical lenses with five-element lenses. The five-element lenses of camera optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 are the first lens L1, the second lens L2, the third lens L3, the fourth lens L4, and the fifth lens L5, respectively. The five-element lenses are divided into two groups (four lenses + one lens), namely the first lens group and the second lens group. The first lens group is closer to the object side than the second lens group.

[0062] The first lens group is the front group, consisting of a first lens L1, a second lens L2, a third lens L3, and a fourth lens L4. The object-side surface of the first lens group is the same as the object-side surface of the first lens L1, and the image-side surface of the first lens group is the same as the image-side surface of the fourth lens L4. The second lens group is the rear group, consisting of a fifth lens L5. The object-side surface of the second lens group is the same as the object-side surface of the fifth lens L5, and the image-side surface of the second lens group is the same as the image-side surface of the fifth lens L5.

[0063] The first lens group is located between the first prism P1 and the second lens group, and the first lens group can move along the optical axes of the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, and 80, making the axial distance between the image side of the first prism P1 and the object side of the first lens group, as well as the axial distance between the image side of the first lens group and the object side of the second lens group, adjustable. Thus, the first lens group is a zoomable group, and the second lens group is a fixed-focal-length group. By moving the first lens group, the focal length of the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 can be changed, allowing the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 to have good imaging effects in both the first and second states. The first state refers to the maximum focal length of the camera lenses 10, 20, 30, 40, 50, 60, 70, and 80mm, while the second state refers to the minimum focal length of the camera lenses 10, 20, 30, 40, 50, 60, 70, and 80mm. For example, the first state can be a telephoto state or a state with an infinity object distance; the second state can be a short focal length state, a macro state, or a state with an object distance of 200mm. In this way, the camera lenses 10, 20, 30, 40, 50, 60, 70, and 80mm can achieve in-focusing by moving the front group for focusing.

[0064] Condition (1) specifies the range of the ratio of focal length fA to image height IH of camera optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 in the first state. Within the range defined by condition (1), camera optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 have a longer focal length fA when the image height IH is fixed, which helps to improve the magnification of camera optical lenses 10, 20, 30, 40, 50, 60, 70, and 80. More preferably, 4.61≤fA / IH≤5.08.

[0065] Condition (2) specifies the range of the ratio of the radius of curvature Rp1 of the object side of the first prism P1 to the radius of curvature Rp2 of the image side of the first prism P1, controlling the concave and convex shapes of the object side and the image side of the first prism P1. Within the range defined by condition (2), it is beneficial to mitigate the degree of deflection of light passing through the first prism P1, which helps to facilitate smooth subsequent propagation. More preferably, -2.60≤Rp1 / Rp2≤0.71.

[0066] Condition (3) specifies the range of the ratio of the focal length f1 of the first lens L1 to the on-axis thickness d1 of the first lens L1. Within the range defined by condition (3), it helps to buffer the change in the incident angle of light with a large angle of view, so that it can be smoothly propagated in the camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, while maintaining the refractive power of the first lens L1 to improve chromatic aberration and enhance imaging quality. More preferably, -23.82≤f1 / d1≤2.59.

[0067] Condition (4) specifies the range of the ratio between the shortest distance BF on the axis from the image side of the fifth lens L5 to the imaging plane Si in the first state and the total optical length TTL of the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, and 80. Within the range defined by condition (4), on the basis of miniaturization, the back focal length of the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 is beneficial to the assembly of the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, and 80. At the same time, the total length of the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 can be effectively controlled. More preferably, 0.14≤BF / TTL≤0.35.

[0068] Condition (5) specifies the range of values ​​for f4 / R8-f5 / R9. Within the range defined by condition (5), the degree of deflection of the edge field of view in the fourth lens L4 and the fifth lens L5 can be effectively controlled, thereby reducing the sensitivity of the entire camera optical lens 10, 20, 30, 40, 50, 60, 70, 80. More preferably, 0.21≤f4 / R8-f5 / R9≤4.26.

[0069] The beneficial effects of this invention are as follows: By dividing the five-element lens into two groups, the front group moves to focus, resulting in a faster and smoother focusing process. Simultaneously, the physical lengths of the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 can remain constant, which helps in the allocation of internal space within the device. Specifying the ratio of focal length to image height for the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 in the first state, the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 have a longer focal length when the image height is fixed, which helps to improve the magnification of the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, and 80. Specifying the concave-convex shape of the first prism P1 helps to mitigate the degree of light deflection after passing through the first prism P1, contributing to smooth subsequent propagation. Specifying the ratio of focal length to thickness of the first lens L1 helps to buffer changes in the incident angle of light at large angles of view. This allows the light to propagate smoothly within the camera optical lenses 10, 20, 30, 40, 50, 60, 70, and 80, while maintaining the refractive power of the first lens L1 to improve chromatic aberration and enhance image quality. The ratio of the distance from the fifth lens L5 to the imaging plane to the total optical length of the camera optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 is specified. Based on miniaturization, the camera optical lenses 10, 20, 30, 40, 50, 60, and 80... The back focal lengths of 70 and 80 are beneficial for the assembly of camera optical lenses of 10, 20, 30, 40, 50, 60, 70, and 80, and can effectively control the overall length of camera optical lenses of 10, 20, 30, 40, 50, 60, 70, and 80; by effectively controlling the degree of deflection of the edge field of view at the fourth lens L4 and the fifth lens L5, the sensitivity of the entire camera optical lens of 10, 20, 30, 40, 50, 60, 70, and 80 is reduced.

[0070] Based on the above conditional expressions and the functions that can be achieved, the characteristics of each lens are further refined as follows.

[0071] Preferably, the focal length of the first prism P1 is fp1, and the sum of the axial distance from the object side surface of the first prism P1 to the reflecting surface and the axial distance from the reflecting surface to the image side surface of the first prism P1 is dp1, satisfying the following relationship:

[0072] -27.20≤fp1 / fA≤139.44(6)

[0073] 0.244≤dp1 / TTL≤0.246(7)

[0074] Condition (6) specifies the range of the ratio between the focal length fp1 of the first prism P1 and the focal length fA of the camera optical lenses 10, 20, 30, 40, 50, 60, 70, and 80 in the first state. Within the range defined by condition (6), it helps to improve the optical performance of the camera optical lenses 10, 20, 30, 40, 50, 60, 70, and 80.
