Description

Camera optical lens 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 popularization of smartphones, the research and design of cameras have also developed rapidly.

[0003] Telephoto cameras can meet consumers' needs for capturing specific targets. However, traditional telephoto cameras have an excessively large overall optical length, which does not meet the design requirements of slim and lightweight smartphones. Periscope telephoto camera designs, on the other hand, can significantly shorten the overall optical length of the camera lens while still meeting the telephoto design requirements.

A camera optical lens that meets all conditions has a long focal length with a fixed image height, which helps improve the system's magnification. It helps to mitigate the degree of light deflection entering the lens, contributing to smooth subsequent propagation. By rationally allocating the system's optical focal length, the system achieves better image quality and lower sensitivity. While achieving miniaturization, the long rear focal length facilitates module assembly and effectively controls the overall length of the optical system. Attached Figure Description

[0117] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of the present invention to enable the reader to better understand the present invention. However, the technical solutions claimed in the present invention can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0118] Referring to the accompanying drawings, the technical solution of the present invention provides a camera optical lens 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, which is composed of a first prism P1 with positive refractive power arranged sequentially from the object side to the image side, and a first lens L1, a second lens L2, a third lens L3, a fourth lens L4, and a fifth lens L5; a reflecting surface RF is provided between the object side and the image side of the first prism P1; the first lens L1, the second lens L2, and the third lens L3 form a first lens group; and the fourth lens L4 and the fifth lens L5 form a first lens group. Lens L5 is the second lens group, which is adjustable along the optical axis of the camera lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100. This allows the camera lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 to switch between a first state and a second state. In the first state, the camera lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 have the longest focal length, while in the second state, they have the shortest focal length.

[0119] The focal length of the camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 in the first state is fA, the image height of the camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 is IH, the radius of curvature of the object side of the first prism P1 is Rp1, the radius of curvature of the image side of the first prism P1 is Rp2, the focal length of the first lens L1 is f1, the back focal length of the camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 is BF, and the total optical length of the camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 is TTL, and satisfies the following relationship:

[0120] 4.00≤fA / IH≤4.80 (1)

[0121] -4.00≤Rp1 / Rp2≤1.20 (2)

[0122] -1.76≤f1 / fA≤1.00 (3)

[0123] 0.12≤BF / TTL≤0.35 (4)

[0124] Among them, the camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 are periscope optical lenses with five-element lenses. The camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 are composed of a first prism P1, a first lens L1, a second lens L2, a third lens L3, a fourth lens L4, and a fifth lens L5 arranged sequentially from the object side to the image side.

[0125] The camera optical lenses of sizes 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 use a five-element lens, namely lens L1, lens L2, lens L3, lens L4, and lens L5. The five-element lenses are divided into two groups (the first three lenses form the front group, and the last two lenses form the rear group), 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.

[0126] The first lens group is the front group, consisting of lens L1, lens L2, and lens L3. The object-side surface of the first lens group is the same as the object-side surface of lens L1, and the image-side surface is the same as the image-side surface of lens L3. The second lens group is the rear group, consisting of lens L4 and lens L5. The object-side surface of the second lens group is the same as the object-side surface of lens L4, and the image-side surface is the same as the image-side surface of lens L5. The rear group, including lens L4 and lens L5, is movable for focusing. This results in a faster and smoother focusing process and helps control focusing artifacts.

[0127] The first lens group is located between the first prism P1 and the second lens group. The second lens group can move along the optical axes of the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100, allowing the axial distance between the image side of the third lens L3 and the object side of the second lens group to be adjustable. Thus, the second lens group is a zoomable group, and the first lens group is a fixed-focal-length group. By moving the second lens group, the focal lengths of the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 can be changed, resulting in good imaging effects for the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 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, 80, 90, and 100, while the second state refers to the minimum focal length of the camera lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100. 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, 80, 90, and 100 can achieve in-focusing by moving the rear group of focus points.

[0128] Condition (1) specifies the ratio of focal length fA to image height IH of camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 in the first state. Within the range defined by condition (1), camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 have a longer focal length when the image height IH is fixed, which helps to improve the magnification of camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100.

[0129] Condition (2) specifies the range of the ratio of the object side curvature radius Rp1 to the image side curvature radius Rp2 of the first prism P1, controlling the shape of the object side and image side of the first prism P1. Within the range defined by condition (2), it helps to mitigate the degree of deflection of light entering the lens and helps to facilitate smooth subsequent propagation.

[0130] Condition (3) specifies the range of the ratio between the focal length f1 of the first lens L1 and the focal length fA of the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 in the first state. By reasonably allocating the optical focal lengths of the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100, within the range defined by condition (3), the imaging optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 have better imaging quality and lower sensitivity.

[0131] Condition (4) specifies the range of ratios between the back focal length and the total optical length of the camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100. By controlling the back focal length of the camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 within the range defined by condition (4), a longer back focal length is beneficial for module assembly while achieving miniaturization. Simultaneously, the total optical length of the camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 can be effectively controlled.

[0132] Under the above conditions, a five-element lens is divided into a first lens group and a second lens group. The second lens group moves to focus, thereby achieving in-focusing for the camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100. By setting the ratio of focal length to image height for the camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100, a longer focal length is achieved with a fixed image height, which helps to improve the focusing efficiency of the camera optical lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100. 0x magnification; the concave-convex shape of the first prism P1 helps to mitigate the deflection of light passing through it; by rationally allocating the focal lengths of the camera lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100, the camera lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 achieve better imaging quality and lower sensitivity; by controlling the back focal lengths of the camera lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100, the total optical length of the camera lenses 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 can be effectively controlled.

[0133] Based on the above conditional expressions and the functions that can be achieved, the characteristics of each lens are further refined as follows.

[0134] The focal length of the fourth lens L4 is f4, and the focal length of the fifth lens L5 is f5, and they satisfy the following relationship:
