Description

Technical Field

[0001] This application relates to the field of optical components, and more specifically, to an optical camera lens. Background Technology

[0002] With increasingly fierce competition in the market for portable electronic devices such as smartphones, many mobile phone manufacturers have begun to spare no effort in improving the craftsmanship and technology of their phones, among which the camera function has become one of the main directions for enhancing the competitiveness of mobile phones.

[0003] Typically, in lens design, many lens designers focus more on how to make the lens have a wider shooting range and optimize distortion. In order to improve the assembly stability of the part of the camera lens close to the imaging plane and reduce lens sensitivity, it is necessary to better control the spacing distance, etc., and thus ignore the many adverse effects of stray light and other phenomena on the lens.

[0021] In an exemplary embodiment of this application, by reasonably setting six lenses, multiple isolators, and a lens barrel, and by combining 10 < (EP45 + CP5) / T56 < 40.0, the thickness, imaging quality, and spacing of the fifth and sixth lenses can be better controlled, reducing the sensitivity of the lens at this position and its impact on the imaging quality of the camera lens. This also helps improve the assembly stability of the portion of the camera lens near the imaging surface. However, this design can easily affect the transmission of subsequent light and the generation of stray light. Based on this, by further setting 0 < d5s / f5 < 1.0 and 0 < d5s / f6 < 1.0, the effective focal length of the fifth and sixth lenses and the inner diameter of the object side of the fifth isolator can be reasonably controlled. This enhances the light divergence effect, helps control the dispersion of light transmitted to the sixth lens, and ensures the uniformity of light divergence from the sixth lens to the imaging surface, improving the overall image quality. It also improves the white arc stray light problem generated in the non-optical area of ​​the fifth lens, reducing the impact of stray light at the fifth lens position on the overall camera lens, thereby improving the imaging quality of the optical camera lens.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this application, and these all fall within the protection scope of this application. For example, the lens groups (i.e., the first to sixth lenses), lens barrel structures, and isolation components in the various embodiments of this application can be arbitrarily combined, and it is not limited to the lens group in one embodiment being combined only with the lens barrel structure, isolation component, etc. of that embodiment. The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] The features, principles and other aspects of this application are described in detail below.

[0047] An optical camera lens according to an exemplary embodiment of this application may include six lenses with refractive power, namely a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. These six lenses are arranged sequentially along the optical axis from the object side to the image side. Any two adjacent lenses among the first to sixth lenses may have a spacing distance. Any one of the first to sixth lenses may have a central thickness along the optical axis.

[0048] According to an exemplary embodiment of this application, each of the first to sixth lenses may have an optical region for optical imaging and a non-optical region extending outward from the outer periphery of the optical region. Generally speaking, the optical region refers to the area of ​​the lens used for optical imaging, while the non-optical region is the structural area of ​​the lens. During the assembly of the optical camera lens, separators can be set at the non-optical regions of each lens using processes such as adhesive bonding, and each lens can be connected to the lens barrel respectively. During the imaging process of the optical camera lens, the optical regions of each lens can transmit light from the object to form an optical path, forming the final optical image; while the non-optical regions of each assembled lens are housed in the lens barrel, which cannot transmit light, thus the non-optical regions do not directly participate in the imaging process of the optical camera lens. It should be noted that, for ease of description, this application describes each lens as divided into two parts: an optical region and a non-optical region. However, it should be understood that the optical region and the non-optical region of the lens can be formed as a whole during the manufacturing process, rather than as two separate parts.

[0049] In one embodiment of this application, the optical lens assembly may include at least one isolator, such as at least one of a first isolator, a second isolator, a third isolator, a fourth isolator, and a fifth isolator. The first isolator may be located on the image side of the first lens and partially contact the image side surface of the first lens, abutting against a non-optical region of the image side surface of the first lens. The second isolator may be located on the image side of the second lens and partially contact the image side surface of the second lens, abutting against a non-optical region of the image side surface of the second lens. The third isolator may be located on the image side of the third lens and partially contact the image side surface of the third lens, abutting against a non-optical region of the image side surface of the third lens. The fourth isolator may be located on the image side of the fourth lens and partially contact the image side surface of the fourth lens, abutting against a non-optical region of the image side surface of the fourth lens. The fifth isolator may be located on the image side of the fifth lens and partially contact the image side surface of the fifth lens, abutting against a non-optical region of the image side surface of the fifth lens. Exemplarily, the first isolator may contact both the non-optical region of the image side surface of the first lens and the non-optical region of the object side surface of the second lens. For example, the object-side surface of the first isolator may contact the non-optical region of the image-side surface of the first lens, and the image-side surface of the first isolator may contact the non-optical region of the object-side surface of the second lens.

[0050] In another embodiment of this application, the optical camera lens may further include a fifth auxiliary isolator and / or a fifth secondary auxiliary isolator. The fifth auxiliary isolator may be located on the image side of the fifth isolator and in contact with the image side portion of the fifth isolator. The fifth secondary auxiliary isolator may be located on the image side of the fifth auxiliary isolator and in contact with the image side portion of the fifth auxiliary isolator.

[0051] An optical camera lens according to an exemplary embodiment of this application may include a lens barrel housing a lens group and multiple spacers. For example, as... Figure 1 As shown, the lens barrel P0 can be used to accommodate the first lens E1 to the sixth lens E6 and the first isolation member P1 to the fifth secondary isolation member P5c.

[0052] According to an exemplary embodiment of this application, the isolation component may include at least one spacer. By reasonably setting the number, thickness, inner diameter, and outer diameter of the spacers, it is beneficial to improve the assembly of the optical camera lens, to block stray light, and to improve the imaging quality of the optical camera lens.

[0053] In an exemplary embodiment, the first lens may have positive or negative refractive power, its object-side surface may be concave, and its image-side surface may be convex; the second lens may have positive refractive power, its object-side surface may be convex, and its image-side surface may be concave; the third lens may have positive refractive power, its object-side surface may be convex, and its image-side surface may be convex; the fourth lens may have negative refractive power, its object-side surface may be concave, and its image-side surface may be convex; the fifth lens may have positive refractive power, its object-side surface may be concave, and its image-side surface may be convex; and the sixth lens may have positive refractive power, its object-side surface may be convex, and its image-side surface may be concave. In an exemplary embodiment, the optical camera lens according to this application satisfies: 10 < (EP45 + CP5) / T56 < 40.0, 0 < d5s / f5 < 1.0, and 0 < d5s / f6 < 1.0, where EP45 is the distance between the image-side surface of the fourth isolator and the object-side surface of the fifth isolator along the optical axis. Figure 13 ), CP5 is the maximum thickness of the fifth isolator along the optical axis, and T56 is the air gap between the fifth and sixth lenses along the optical axis. Figure 13 f5 is the effective focal length of the fifth lens, f6 is the effective focal length of the sixth lens, and d5s is the inner diameter of the object side of the fifth isolator. More specifically, d5s and f5 can further satisfy: 0.1 < d5s / f5 < 1.0, and d5s and f6 can further satisfy: 0.1 < d5s / f6 < 0.5.

[0054] This application provides a six-element lens. Generally, the larger the EP45, the worse the lens assembly stability. Therefore, to meet the requirements for lens assembly stability, the range of EP45 needs to be reasonably set. In this application, by reasonably setting the six lenses, multiple spacers, and the lens barrel, and combining 10 < (EP45 + CP5) / T56 < 40.0, the thickness, image quality, and spacing of the fifth and sixth lenses can be better controlled, reducing the sensitivity of the lenses at this position and their impact on the image quality of the camera lens. It also helps improve the assembly stability of the portion of the camera lens near the imaging plane. However, this design can easily affect the transmission of subsequent light and the generation of stray light. Based on this, by setting 0 < d5s / f5 < 1.0 and 0 < d5s / f6 < 1.0, the effective focal length of the fifth and sixth lenses and the inner diameter of the object side of the fifth isolator can be reasonably controlled. This can enhance the light divergence effect, help control the dispersion state of light transmitted to the sixth lens, and ensure the uniformity of light divergence from the sixth lens to the imaging surface, thereby improving the overall image quality. At the same time, it can also improve the white arc stray light problem generated in the non-optical area of ​​the fifth lens, reduce the impact of stray light at the position of the fifth lens on the overall image lens, and thus improve the imaging quality of the optical image lens.

[0055] like Figure 14 The image shows a white arc spot diagram of the stray light energy angle of an optical camera lens satisfying 1 < (EP45 + CP5) / T56 < 10, d5s / f5 < 0, and d5s / f6 < 0 (e.g., (EP45 + CP5) / T56 = 8.90, d5s / f5 = -0.82, d5s / f6 = -0.37). The maximum energy intensity of the stray light is approximately 0.000001415 lm / mm. 2 The total energy intensity is approximately 0.000000036 lm. For example... Figure 15 The image shows a white arc spot diagram of the stray light energy angle of an optical camera lens that satisfies (EP45+CP5) / T56 > 40, d5s / f5 > 1.0, and d5s / f6 > 1.0 (e.g., (EP45+CP5) / T56 = 43.14, d5s / f5 = 1.52, d5s / f6 = 1.43). The maximum energy intensity of the stray light is approximately 0.000001471 lm / mm. 2 The total energy intensity is approximately 0.000000033 lm. For example... Figure 16 The image shows a white arc spot diagram of the stray light energy angle of an optical camera lens that satisfies 10 < (EP45 + CP5) / T56 < 40.0, 0 < d5s / f5 < 1.0, and 0 < d5s / f6 < 1.0 (e.g., (EP45 + CP5) / T56 = 24.46, d5s / f5 = 0.61, d5s / f6 = 0.38). The maximum energy intensity of the stray light is approximately 0.000000515 lm / mm.2 The total energy intensity is approximately 0.000000013 lm.

[0056] from Figures 14 to 16 As can be seen from this, compared to Figure 14 and Figure 15 The diagram shown is a white arc spot pattern representing the stray light energy angle of the optical camera lens. Figure 16 The diagram shown is a white arc spot pattern representing the stray light energy angle of the optical camera lens. The maximum energy intensity of the stray light is relatively low. It can be seen that when the optical parameters d5s / f5 and d5s / f6 are controlled within a reasonable range, such as 0 < d5s / f5 < 1.0 and 0 < d5s / f6 < 1.0, the maximum energy intensity of the stray light from the optical camera lens is low, the stray light reduction is significant, and the stray light improvement effect is excellent.

[0057] In an exemplary embodiment, the optical camera lens according to this application can satisfy: 0 < f2 / f < 110 and -1.0 < EP12 / f2 - EP12 / R4 < 0, where f2 is the effective focal length of the second lens, f is the total effective focal length of the optical camera lens, and EP12 is the distance between the image side of the first isolator and the object side of the second isolator along the optical axis. Figure 13 R4 is the radius of curvature of the image-side surface of the second lens. Satisfying 0 < f2 / f < 110 and -1.0 < EP12 / f2 - EP12 / R4 < 0 allows for a smaller radius of curvature on the second lens surface, resulting in better shaping, while maintaining the effective focal length of the second lens and the total effective focal length of the lens. Furthermore, controlling the distance between the image-side surface of the first isolator and the object-side surface of the second isolator improves the lens assembly stability. Additionally, controlling the thickness of the second lens and the air gap between the first and second lenses within a reasonable range enhances the selectivity of the first and second isolators, increases the space for stray light improvement, and ultimately improves the overall stray light quality of the lens.

[0058] In an exemplary embodiment, the optical camera lens according to this application satisfies: -1.0 < f3 / f4 < 0 and 1.5 < d3s / f3 - D3s / f4 < 2.5, where f3 is the effective focal length of the third lens, f4 is the effective focal length of the fourth lens, and d3s is the inner diameter of the object side of the third isolator. Figure 13 D3s is the outer diameter of the object side of the third spacer. Figure 13Satisfying -1.0 < f3 / f4 < 0 and 1.5 < d3s / f3 - D3s / f4 < 2.5 not only allows the effective focal length of the optical camera lens to be controlled within a reasonable range, but also reduces light leakage problems caused by the third and fourth lenses. Furthermore, by controlling the effective focal length of the third and fourth lenses, the outer diameter of these two lenses can be reasonably constrained, and their inner diameter can be controlled simultaneously to intercept light leakage beams passing through the edges of the effective diameter of the third and fourth lenses, thereby reducing the risk of light leakage and improving the image quality of the lens.

[0059] In an exemplary embodiment, the optical camera lens according to this application satisfies: -5.0 < f4 / (EP34+CT4) < -2.0, where f4 is the effective focal length of the fourth lens, and EP34 is the distance between the image-side surface of the third isolator and the object-side surface of the fourth isolator along the optical axis. Figure 13 CT4 is the center thickness of the fourth lens on the optical axis. Satisfying -5.0 < f4 / (EP34+CT4) < -2.0 ensures the height of light passing through the fourth lens, meeting the image height requirements of the optical camera lens. Furthermore, by controlling the distance between the image side of the third isolator and the object side of the fourth isolator along the optical axis, and by adjusting the center thickness of the fourth lens on the optical axis, the shape and contour of the fourth lens can be rationally set, thereby controlling the height of light passing through the fourth lens, ensuring the imaging height of the optical camera lens, and meeting the shooting requirements.

[0060] In an exemplary embodiment, the optical camera lens according to this application satisfies: 1.62 < (N4 + N5) / 2 < 1.80 and 0 < d4s / |(f4 + f5)| < 1.0, where N4 is the refractive index of the fourth lens, N5 is the refractive index of the fifth lens, and d4s is the inner diameter of the object side of the fourth isolator. Figure 13 f4 is the effective focal length of the fourth lens, and f5 is the effective focal length of the fifth lens. Satisfying 1.62 < (N4 + N5) / 2 < 1.80 and 0 < d4s / |(f4 + f5)| < 1.0 allows control over the dispersion of light rays reaching the fifth lens, ensuring uniformity of light divergence from the fifth lens to the imaging plane. Furthermore, controlling the refractive indices of the fourth and fifth lenses constrains their outer diameters, simultaneously controlling the inner diameter of the object-side surface of the fourth isolator, reducing the risk of light leakage, and improving lens image quality.

[0061] In an exemplary embodiment, the optical camera lens according to this application can satisfy: 3.0 < L / (CT5+T56+CT6) < 4.0, where L is the distance between the object-side end and the image-side end of the lens barrel along the optical axis. Figure 13CT5 is the center thickness of the fifth lens on the optical axis, CT6 is the center thickness of the sixth lens on the optical axis, and T56 is the air gap between the fifth and sixth lenses on the optical axis. Satisfying 3.0 < L / (CT5 + T56 + CT6) < 4.0 ensures that the sixth lens is contained within the image-side enclosure of the lens barrel, preventing scratches on the image-side of the sixth lens and thus avoiding problems with the lens's appearance. Simultaneously, since scratches on the image-side of the sixth lens affect the stray light and ghosting effects of the optical camera lens, this application utilizes the lens barrel's enclosure of the lens to effectively prevent stray light and ghosting caused by lens scratches, improving the imaging effect and image quality of the optical camera lens.

[0062] In an exemplary embodiment, the optical camera lens according to this application satisfies: 5mm < D5s / |R8 / R9| < 10.0mm, where D5s is the outer diameter of the object side of the fifth spacer. Figure 13 R8 is the radius of curvature of the image-side surface of the fourth lens, and R9 is the radius of curvature of the object-side surface of the fifth lens. Satisfying 5mm < D5s / |R8 / R9| < 10.0mm allows control over the divergence of light, facilitating more uniform light transmission to the sixth lens. Furthermore, by controlling the outer diameter of the object-side surface of the fifth isolator, the outer diameters of the fourth and fifth lenses can be controlled, reducing the step length between lenses and improving lens forming feasibility and assembly stability.

[0063] In an exemplary embodiment, the optical camera lens according to this application satisfies: -10.0 < R9 / R12 < -1.0 and 4.0 < f56 / (EP45+T56) < 10.0, where R9 is the radius of curvature of the object-side surface of the fifth lens, R12 is the radius of curvature of the image-side surface of the sixth lens, f56 is the combined focal length of the fifth and sixth lenses, and EP45 is the distance between the image-side surface of the fourth isolator and the object-side surface of the fifth isolator along the optical axis. Figure 13 T56 is the air gap between the fifth and sixth lenses on the optical axis. Satisfying -10.0 < R9 / R12 < -1.0 and 4.0 < f56 / (EP45+T56) < 10.0 ensures that the height of light passing through the sixth lens meets the image height requirements of the optical camera lens. The combined focal length of the fifth and sixth lenses, the distance between the fourth spacer and the fifth spacer, and the air gap between the fifth and sixth lenses on the optical axis collectively determine the shape of the fifth and sixth lenses. Satisfying -10.0 < R9 / R12 < -1.0 and 4.0 < f56 / (EP45+T56) < 10.0 controls the height of light passing through the fifth and sixth lenses, ensuring the image height of the optical camera lens and thus meeting the shooting requirements.

[0064] In an exemplary embodiment, the optical camera lens according to this application satisfies: -2.0 < d0s / R1 < -0.5, where R1 is the radius of curvature of the object-side surface of the first lens, and d0s is the inner diameter of the object-side end of the lens barrel. Figure 13 If -2.0 < d0s / R1 < -0.5, the shooting range, i.e. the size of the field of view, can be controlled by controlling the radius of curvature of the object side of the first lens and the inner diameter of the object side end of the lens barrel, thereby ensuring the performance requirements of the optical camera lens.

[0065] In an exemplary embodiment, the optical camera lens according to this application satisfies: 110.0° < FOV < 120.0° and 0.3 < d0s / d0m < 0.7, where FOV is the maximum field of view of the optical camera lens, and d0s is the inner diameter of the object-side end of the lens barrel. Figure 13 ), d0m is the inner diameter of the image-side end of the microscope tube ( Figure 13 The parameters 110.0° < FOV < 120.0° and 0.3 < d0s / d0m < 0.7 are satisfied, which allows light to enter at a certain field of view angle through the inner diameter of the object-side end of the lens barrel, while reducing the light interception phenomenon at the image-side end of the lens barrel, thus helping to ensure normal shooting needs.

[0066] In an exemplary embodiment, the maximum diameter of any one of the first to fourth lenses is smaller than the maximum diameter of the fifth lens. This arrangement helps improve the assembly stability of the fifth lens, thereby enhancing the assembly stability and practicality of the optical camera lens. Exemplarily, the maximum diameters of the first to fifth lenses can increase sequentially. This ensures that the outer diameter of the isolator on the image side of each lens is greater than the maximum outer diameter of that lens, guaranteeing that stray light paths in non-optical areas are completely blocked, thus improving the image quality of the optical camera lens.

[0067] In an exemplary embodiment, the surfaces of the first lens and / or the sixth lens have at least one inflection point. In other words, at least one of the first and sixth lenses has at least one inflection point on its object-side or image-side surface. This arrangement can increase the height of light rays passing through the lens, which is beneficial for adjusting light rays at large angles, facilitates mutual compensation of spherical aberrations of the lenses, and simultaneously balances and controls the overall low-order aberrations of the lens.

[0068] In an exemplary embodiment, the surface of the first lens has at least one inflection point. The optical imaging lens according to this application satisfies: 0 < (DT11 - Yc11) / d1s < 0.6, where DT11 is the maximum effective radius of the object-side surface of the first lens, Yc11 is the distance between the inflection point on the object-side surface of the first lens and the intersection of the object-side surface of the first lens and the optical axis along a direction perpendicular to the optical axis (i.e., Yc11 is the perpendicular distance from the inflection point on the object-side surface of the first lens to the optical axis), and d1s is the inner diameter of the object-side surface of the first isolator. In this application, the inflection point on the object-side surface of the first lens is beneficial for the convergence of light rays from various fields of view. Satisfying 0 < (DT11 - Yc11) / d1s < 0.6 helps to control the ratio of the difference between the maximum effective radius of the object-side surface of the first lens and the perpendicular distance from the inflection point to the optical axis to the inner diameter of the object-side surface of the first isolator within a reasonable numerical range, thereby helping to reduce the size of the lens, achieve ultra-thinness, and save space occupied by the lens.

[0069] In an exemplary embodiment, the surface of the sixth lens has at least one inflection point. The optical imaging lens according to this application satisfies: 2.0 < d5s / Yc62 < 3.0, where d5s is the inner diameter of the object-side surface of the fifth isolator (…). Figure 13 Yc62 is the distance between the inflection point on the image-side surface of the sixth lens and the intersection of the image-side surface of the sixth lens and the optical axis, along a direction perpendicular to the optical axis. Satisfying 2.0 < d5s / Yc62 < 3.0 allows for a suitable increase in the degree of inflection on the image-side surface of the sixth lens relative to the optical axis, resulting in a larger height difference between the light rays entering and exiting the sixth lens. This, in turn, elevates the height of the light rays passing through the sixth lens. Simultaneously, the inner diameter of the side surface of the fifth isolator can be appropriately reduced to improve its blocking effect on light rays exiting the non-optical area of ​​the fifth lens, thereby reducing stray white arc light generated in the non-optical area of ​​the fifth lens.

[0070] In an exemplary embodiment, the optical camera lens according to this application satisfies: 0 < (d5bm + d5cm) / f6 < 2.0, where d5bm is the inner diameter of the image-side surface of the fifth auxiliary isolator. Figure 13 ), d5cm is the inner diameter of the image side of the fifth auxiliary isolation component. Figure 13 f6 is the effective focal length of the sixth lens. Typically, in lens design, to meet the total effective focal length requirement, the air gap between adjacent components may be increased. This application improves the image quality of the optical camera lens by setting a fifth auxiliary isolation element and a fifth secondary auxiliary isolation element, satisfying 0 < (d5bm + d5cm) / f6 < 2.0. This not only improves the shaping of the fifth isolation element but also, by adding auxiliary isolation elements such as the fifth auxiliary isolation element and the fifth secondary auxiliary isolation element, blocks stray light reflected from the inner diameter surface of the fifth isolation element.

[0071] In an exemplary embodiment, the optical camera lens according to this application further includes an aperture stop disposed between the second lens and the third lens. Optionally, the optical camera lens may also include a filter for correcting color deviation and / or a protective glass for protecting the photosensitive element located on the imaging surface. This application proposes an optical camera lens with characteristics such as a large field of view, low stray light, high stability, high yield, and high imaging quality. The optical camera lens according to the above embodiments of this application can employ multiple lenses, such as the six lenses mentioned above. By rationally allocating the refractive power, surface shape, material, center thickness of each lens, and on-axis spacing between each lens, incident light can be effectively converged, the overall optical length of the imaging lens can be reduced, and the manufacturability of the imaging lens can be improved, making the optical camera lens more conducive to production and processing. In the optical camera lens of the above embodiments of this application, by setting an isolator between adjacent lenses and designing the inner and outer diameters of the isolator according to the optical path, stray light can be effectively blocked and eliminated, improving the imaging quality of the lens.

[0072] In embodiments of this application, at least one of the mirror surfaces of each lens is an aspherical mirror surface; that is, at least one mirror surface from the object-side surface of the first lens to the image-side surface of the sixth lens is an aspherical mirror surface. The characteristic of an aspherical lens is that its curvature changes continuously from the lens center to the lens periphery. Unlike a spherical lens, which has a constant curvature from the lens center to the lens periphery, an aspherical lens has better curvature radius characteristics, offering advantages in improving distortion aberrations and astigmatism. By using an aspherical lens, aberrations occurring during imaging can be eliminated as much as possible, thereby improving image quality. Optionally, at least one of the object-side and image-side surfaces of each of the first, second, third, fourth, fifth, and sixth lenses is an aspherical mirror surface. Optionally, both the object-side and image-side surfaces of each of the first, second, third, fourth, fifth, and sixth lenses are aspherical mirror surfaces.

[0073] However, those skilled in the art will understand that the number of lenses constituting the optical camera lens can be varied to obtain the various results and advantages described herein without departing from the technical solutions claimed in this application. For example, although six lenses are described as an example in the embodiments, the optical camera lens is not limited to including six lenses. If desired, the optical camera lens may also include other numbers of lenses.
