[0018] This application also provides an optical camera lens that, along the optical axis from the object side to the image side, sequentially includes a lens group, a plurality of spacers, and a lens barrel for accommodating the lens group and the plurality of spacers. The lens group, along the optical axis from the object side to the image side, sequentially includes a first lens with positive optical power, a second lens with negative optical power, a third lens with negative optical power, a fourth lens with positive optical power, a fifth lens with negative optical power, a sixth lens with positive optical power, and a seventh lens with negative optical power. The object side of the first lens is convex, the image side of the second lens is concave, and the edge region of the image side of the first lens interlocks with the edge region of the object side of the second lens. The number of lenses with optical power in the lens group is seven. The plurality of spacers includes a fourth spacer located on the image side of the fourth lens and in contact with a portion of the image side of the fourth lens, a fifth spacer located on the image side of the fifth lens and in contact with a portion of the image side of the fifth lens, and a sixth spacer located on the image side of the sixth lens and in contact with a portion of the image side of the sixth lens. The optical camera lens can satisfy: 0.5 < (CT5 + T56 + CT6) / (EP45 + EP56) < 1.1, where CT5 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, T56 is the air gap between the fifth and sixth lenses on the optical axis, EP45 is the distance between the image side of the fourth spacer element and the object side of the fifth spacer element along the optical axis, and EP56 is the distance between the image side of the fifth spacer element and the object side of the sixth spacer element along the optical axis.

[0019] In an exemplary embodiment of this application, by reasonably setting the optical power of the seven lenses, the surface shape and positional relationship of the edge regions of the first and second lenses, and the air gap between adjacent lenses to satisfy T12 < T23, T34 < T45, and T56 < T67, it is beneficial to rationally arrange the spatial positional relationship between the lenses, effectively adjust the path of light and the degree of light convergence or divergence, reduce the sensitivity of the lens, and improve the imaging quality and stability of the lens. Specifically, based on the reasonable setting of the optical power of the seven lenses and the air gap between adjacent lenses, the object-side surface of the first lens is set to be convex, which can converge light to achieve the shooting of distant targets; the image-side surface of the second lens is set to be concave, which can diverge light to achieve the shooting of close-range targets. At the same time, the edges of the first and second lenses are interlocked, which helps to reduce the size of the optical camera lens and improve the stability of the lens structure. Based on this, by setting multiple spacer elements and lens barrels, and combining them with 1.2 < L / ImgH < 1.4, 8.0 < R5 / f3 < 14.5, and 29.0 < EP23 / (CT3×N3) + T23 / CP3 < 44.0, it is beneficial to enable the lens to simultaneously possess characteristics such as ultra-thinness, large image plane, and high stability of the third lens assembly. Specifically, setting the lens to satisfy 1.2 < L / ImgH < 1.4 is beneficial to enabling the lens to possess characteristics such as ultra-thinness and large image plane. Generally, in ultra-thin lenses with large image planes, the lens located near the center has higher sensitivity. Based on this, this application controls the effective focal length of the third lens near the center and the radius of curvature of the object side of the third lens within a specific range, and controls the thickness of the third lens, the air gap between adjacent lenses, and the adjacent spacer elements to satisfy 29.0 < EP23 / (CT3×N3) + T23 / CP3 < 44.0, which can effectively reduce the sensitivity of the third lens and improve the assembly stability of the third lens.

[0020] In another exemplary embodiment of this application, by reasonably setting the optical power of the seven lenses and the surface shape and positional relationship of the edge regions of the first and second lenses, it is beneficial to effectively adjust the path of light and the degree of light convergence or divergence, reduce the size of the lens, and improve the imaging quality and stability of the lens. Specifically, based on reasonably setting the optical power of the seven lenses, setting the object-side surface of the first lens to be convex allows light to converge, enabling the shooting of distant targets; setting the image-side surface of the second lens to be concave allows light to diverge, enabling the shooting of close-range targets. At the same time, setting the edges of the first and second lenses to interlock helps to reduce the size of the optical camera lens and improve the stability of the lens structure. Based on this, by setting multiple spacer elements and lens barrels and controlling 0.8 < EP01 / CT1 < 1.2, the shape of the first lens can be controlled to make it less prone to breakage during assembly. Controlling -0.5 < (D0s-d0s) / (D1s-d1s) < 1.0 is beneficial to improving the assembly stability of the first lens, ensuring the overall shape and assembly stability of the first lens, and thus further reducing the on-axis spherical aberration and off-axis coma of the lens.

[0021] In another exemplary embodiment of this application, by reasonably setting the optical power of the seven lenses and the surface shape and positional relationship of the edge regions of the first and second lenses, it is beneficial to effectively adjust the path of light and the degree of light convergence or divergence, reduce the size of the lens, and improve the imaging quality and stability of the lens. Specifically, based on reasonably setting the optical power of the seven lenses, setting the object side of the first lens to be convex can converge light to achieve the shooting of distant targets; setting the image side of the second lens to be concave can diverge light to achieve the shooting of close targets. At the same time, setting the edges of the first and second lenses to interlock helps to reduce the size of the optical camera lens and improve the stability of the lens structure. On this basis, by setting multiple spacer elements and lens barrels and matching -34.0 < f2×N2 / (T23+EP34) < -16.0, the deflection angle of light after passing through the first to fourth lenses can be reduced, and the distance between the second and third lenses and the distance between the third and fourth spacer elements can be controlled within a reasonable range, thereby improving the assembly stability of the first to fourth lenses.

[0022] In another exemplary embodiment of this application, by reasonably setting the optical power of the seven lenses and the surface shape and positional relationship of the edge regions of the first and second lenses, it is beneficial to effectively adjust the path of light and the degree of light convergence or divergence, reduce the size of the lens, and improve the imaging quality and stability of the lens. Specifically, based on the reasonable setting of the optical power of the seven lenses, the object side of the first lens is set to be convex, which can converge light to achieve the shooting of distant targets; the image side of the second lens is set to be concave, which can diverge light to achieve the shooting of close targets. At the same time, the edges of the first and second lenses are interlocked, which helps to reduce the size of the optical camera lens and improve the stability of the lens structure. On this basis, by setting multiple spacer elements and lens barrels and matching 0.5 < (CT5 + T56 + CT6) / (EP45 + EP56) < 1.1, the aperture of the fifth, sixth, and seventh lenses can be reduced, while ensuring that the illuminance of the edge field of view does not decrease, thereby helping to ensure the overall brightness of the image.

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 the seventh lenses), lens barrel structures, and spacer elements in the various embodiments of this application can be arbitrarily combined, and it is not limited to the lens group in one embodiment being only combined with the lens barrel structure, spacer elements, etc. of that embodiment. The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] The features, principles and other aspects of this application are described in detail below.

[0045] An optical camera lens according to an exemplary embodiment of this application may include seven lenses with optical power, namely a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens. These seven lenses are arranged sequentially along the optical axis from the object side to the image side. Any two adjacent lenses among the first to seventh lenses may have a spacing distance. Any lens among the first to seventh lenses may have a center thickness along the optical axis.

[0046] According to an exemplary embodiment of this application, each of the first to seventh 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, spacer elements 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. 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 the assembled lenses 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.

[0047] In an exemplary embodiment of this application, an optical camera lens may include at least one spacer element, such as at least one of a first spacer element, a second spacer element, a third spacer element, a fourth spacer element, a fifth spacer element, and a sixth spacer element. The first spacer element may be located on the image side of a first lens and partially contact the image side surface of the first lens, and may abut against a non-optical region of the image side surface of the first lens. The second spacer element may be located on the image side of a second lens and partially contact the image side surface of the second lens, and may abut against a non-optical region of the image side surface of the second lens. The third spacer element may be located on the image side of a third lens and partially contact the image side surface of the third lens, and may abut against a non-optical region of the image side surface of the third lens. The fourth spacer element may be located on the image side of a fourth lens and partially contact the image side surface of the fourth lens, and may abut against a non-optical region of the image side surface of the fourth lens. The fifth spacer element may be located on the image side of a fifth lens and partially contact the image side surface of the fifth lens, and may abut against a non-optical region of the image side surface of the fifth lens. The sixth spacer element may be located on the image side of the sixth lens and in partial contact with the image side surface of the sixth lens, and may abut against the non-optical area of ​​the image side surface of the sixth lens.

[0048] like Figure 1 As shown, an optical camera lens according to an exemplary embodiment of this application may include a lens barrel P0 that houses a lens group and a plurality of spacer elements. Exemplarily, the lens barrel P0 may be a one-piece lens barrel for housing first lenses E1 to seventh lenses E7 and first spacer elements P1 to sixth spacer elements P6.

[0049] According to an exemplary embodiment of this application, the spacer element 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.

[0050] In an exemplary embodiment, the first lens may have positive optical power; the second lens may have negative optical power; the third lens may have negative optical power; the fourth lens may have positive optical power; the fifth lens may have negative optical power; the sixth lens may have positive optical power; and the seventh lens may have negative optical power.

[0051] In an exemplary embodiment, the object-side surface of the first lens is convex; the image-side surface of the second lens is concave; and the edge region of the image-side surface of the first lens and the edge region of the object-side surface of the second lens are interlocked.

[0052] In an exemplary embodiment, the optical camera lens according to this application satisfies the following: T12 < T23, T34 < T45, T56 < T67, 1.2 < L / ImgH < 1.4, 8.0 < R5 / f3 < 14.5, and 29.0 < EP23 / (CT3×N3) + T23 / CP3 < 44.0, where T12 is the air gap between the first and second lenses on the optical axis, T23 is the air gap between the second and third lenses on the optical axis, T34 is the air gap between the third and fourth lenses on the optical axis, and T45 is the air gap between the fourth lens and the second lens. The air gap between the fifth and sixth lenses on the optical axis, T56 is the air gap between the fifth and sixth lenses on the optical axis, T67 is the air gap between the sixth and seventh lenses on the optical axis, L is the distance between the object-side end and the image-side end of the lens barrel along the optical axis, ImgH is half the diagonal length of the effective pixel area on the imaging surface of the optical camera lens, R5 is the radius of curvature of the object-side surface of the third lens, f3 is the effective focal length of the third lens, and EP23 is the distance between the image-side surface of the second spacer element and the object-side surface of the third spacer element along the optical axis. Figure 12 ), CT3 is the center thickness of the third lens on the optical axis, N3 is the refractive index of the third lens, and CP3 is the maximum thickness of the third spacer element. Figure 12 ).

[0053] In this application, by rationally setting the optical power of the seven lenses, the surface shape and positional relationship of the edge regions of the first and second lenses, and the air gap between adjacent lenses to satisfy T12 < T23, T34 < T45, and T56 < T67, it is beneficial to rationally arrange the spatial positional relationship between the lenses, effectively adjust the path of light and the degree of light convergence or divergence, reduce the sensitivity of the lens, and improve the imaging quality and stability of the lens. Specifically, based on the rational setting of the optical power of the seven lenses and the air gap between adjacent lenses, the object-side surface of the first lens is set to be convex, which can converge light to achieve the shooting of distant targets; the image-side surface of the second lens is set to be concave, which can diverge light to achieve the shooting of close-range targets. At the same time, the edges of the first and second lenses are interlocked, which helps to reduce the size of the optical camera lens and improve the stability of the lens structure. Based on this, by setting multiple spacer elements and lens barrels, and combining them with 1.2 < L / ImgH < 1.4, 8.0 < R5 / f3 < 14.5, and 29.0 < EP23 / (CT3×N3) + T23 / CP3 < 44.0, it is beneficial to enable the lens to simultaneously possess characteristics such as ultra-thinness, large image plane, and high stability of the third lens assembly. Specifically, setting the lens to satisfy 1.2 < L / ImgH < 1.4 is beneficial to enabling the lens to possess characteristics such as ultra-thinness and large image plane. Generally, in ultra-thin lenses with large image planes, the lens located near the center has higher sensitivity. Based on this, this application controls the effective focal length of the third lens near the center and the radius of curvature of the object side of the third lens within a specific range, and controls the thickness of the third lens, the air gap between adjacent lenses, and the adjacent spacer elements to satisfy 29.0 < EP23 / (CT3×N3) + T23 / CP3 < 44.0, which can effectively reduce the sensitivity of the third lens and improve the assembly stability of the third lens.

[0054] This application conducted multiple sets (more than 10 sets) of tests on optical camera lenses that meet different technical parameters. The test results of multiple sets of lenses with the same technical parameters are not significantly different. The following are examples of test results of several sets of optical camera lenses that meet different technical parameters.

[0055] As shown in the table below, Sample 1 shows the sensitivity between adjacent lenses in an optical camera lens that satisfies 1.2 < L / ImgH < 1.4, 8.0 < R5 / f3 < 14.5, and EP23 / (CT3×N3) + T23 / CP3 = 25.0. Sample 2 shows the sensitivity between adjacent lenses in an optical camera lens that satisfies 1.2 < L / ImgH < 1.4, 8.0 < R5 / f3 < 14.5, and EP23 / (CT3×N3) + T23 / CP3 = 43.66. Sample 3 shows the sensitivity between adjacent lenses in an optical camera lens that satisfies 1.2 < L / ImgH < 1.4, 8.0 < R5 / f3 < 14.5, and EP23 / (CT3×N3) + T23 / CP3 = 49.

[0056]

[0057] As can be seen from the table above, samples 1 to 3 all satisfy 1.2 < L / ImgH < 1.4 and 8.0 < R5 / f3 < 14.5. Based on this, there are certain differences in the optical technical parameter EP23 / (CT3×N3)+T23 / CP3 among samples 1 to 3. When the value of the optical technical parameter EP23 / (CT3×N3)+T23 / CP3 changes, it will cause a significant change in the sensitivity between adjacent lenses, such as the sensitivity Sp2 between the second and third lenses. Specifically, in sample 1, EP23 / (CT3×N3)+T23 / CP3 = 25.0 (i.e., EP23 / (CT3×N3)+T23 / CP3 < 29.0), resulting in Sp2 = 29.32, which is relatively large and does not meet the design requirements. In Sample 3, EP23 / (CT3×N3)+T23 / CP3 = 49 (i.e., EP23 / (CT3×N3)+T23 / CP3 > 44.0), resulting in Sp2 = 27.43, which is relatively large and does not meet the design requirements. Conversely, in Sample 2, EP23 / (CT3×N3)+T23 / CP3 = 43.66 (i.e., 29.0 < EP23 / (CT3×N3)+T23 / CP3 < 44.0), resulting in Sp2 = 11.0, which is relatively small and meets the design requirements. It is evident that the optical parameter EP23 / (CT3×N3)+T23 / CP3 has a significant impact on Sp2. Compared to Samples 1 and 3, the sensitivity between adjacent lenses in Sample 2, such as the sensitivity Sp2 between the second and third lenses, is smaller. This application, by setting 1.2 < L / ImgH < 1.4, 8.0 < R5 / f3 < 14.5, and 29.0 < EP23 / (CT3×N3) + T23 / CP3 < 44.0, can reduce the sensitivity caused by air gaps between adjacent lenses, improve the assembly stability of optical camera lenses, reduce the step difference between lenses, and improve the yield of lens groups.

[0058] also, Figure 13 This is a defocus curve diagram of the optical camera lens in Sample 2. From... Figure 13 As can be seen from the data, the peak of the defocus curve of the optical camera lens in Sample 2 is relatively concentrated, indicating that the lens has a small focus shift and the imaging effect is relatively clear.

[0059] In an exemplary embodiment, the optical camera lens according to this application can satisfy: 0.8 < EP01 / CT1 < 1.2 and -0.5 < (D0s-d0s) / (D1s-d1s) < 1.0, where EP01 is the distance between the object-side end of the lens barrel and the object-side surface of the first spacer element in the direction along the optical axis. Figure 12 ), CT1 is the center thickness of the first lens on the optical axis, and D1s is the outer diameter of the object side of the first spacer element. Figure 12 ), d1s is the inner diameter of the object side of the first spacer element ( Figure 12 D0s is the outer diameter of the object-side end of the microscope tube. Figure 12 ), d0s is the inner diameter of the object-side end of the microscope tube ( Figure 12 ).

[0060] In this application, by rationally setting the optical power of the seven lenses and the surface shape and positional relationship of the edge regions of the first and second lenses, it is beneficial to effectively adjust the path of light and the degree of light convergence or divergence, reduce the size of the lens, and improve the imaging quality and stability of the lens. Specifically, based on the rational setting of the optical power of the seven lenses, setting the object side of the first lens to be convex allows light to converge, enabling the shooting of distant targets; setting the image side of the second lens to be concave allows light to diverge, enabling the shooting of close-range targets. At the same time, setting the edges of the first and second lenses to interlock helps to reduce the size of the optical camera lens and improve the stability of the lens structure. On this basis, by setting multiple spacer elements and lens barrels and controlling 0.8 < EP01 / CT1 < 1.2, the shape of the first lens can be controlled to prevent breakage during assembly, and controlling -0.5 < (D0s - d0s) / (D1s - d1s) < 1.0 helps to improve the assembly stability of the first lens, ensuring the overall shape and assembly stability of the first lens, and thus further reducing the on-axis spherical aberration and off-axis coma of the lens.

[0061] In an exemplary embodiment, the optical camera lens according to this application satisfies: -34.0 < f2 × N2 / (T23 + EP34) < -16.0, where f2 is the effective focal length of the second lens, N2 is the refractive index of the second lens, T23 is the air gap between the second and third lenses on the optical axis, and EP34 is the distance between the image side of the third spacer element and the object side of the fourth spacer element along the optical axis. Figure 12 ).

[0062] In this application, by rationally setting the optical power of the seven lenses and the surface shape and positional relationship of the edge regions of the first and second lenses, it is beneficial to effectively adjust the path of light and the degree of light convergence or divergence, reduce the size of the lens, and improve the imaging quality and stability of the lens. Specifically, based on the rational setting of the optical power of the seven lenses, setting the object side of the first lens to be convex allows light to converge, enabling the shooting of distant targets; setting the image side of the second lens to be concave allows light to diverge, enabling the shooting of close-range targets. At the same time, setting the edges of the first and second lenses to interlock helps to reduce the size of the optical camera lens and improve the stability of the lens structure. On this basis, by setting multiple spacer elements and lens barrels and matching -34.0 < f2×N2 / (T23+EP34) < -16.0, the deflection angle of light after passing through the first to fourth lenses can be reduced, and the spacing between the second and third lenses and the third and fourth spacer elements can be controlled within a reasonable range, thereby improving the assembly stability of the first to fourth lenses.

[0063] In an exemplary embodiment, the optical camera lens according to this application satisfies: 0.5 < (CT5 + T56 + CT6) / (EP45 + EP56) < 1.1, where CT5 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, T56 is the air gap between the fifth and sixth lenses on the optical axis, and EP45 is the distance between the image side of the fourth spacer element and the object side of the fifth spacer element along the optical axis. Figure 12 ), EP56 is the distance between the image side of the fifth spacer element and the object side of the sixth spacer element along the optical axis. Figure 12 ).

[0064] In this application, by rationally setting the optical power of the seven lenses and the surface shape and positional relationship of the edge regions of the first and second lenses, it is beneficial to effectively adjust the path of light and the degree of light convergence or divergence, reduce the size of the lens, and improve the imaging quality and stability of the lens. Specifically, based on the rational setting of the optical power of the seven lenses, the object side of the first lens is set to be convex, which can converge light to achieve the shooting of distant targets; the image side of the second lens is set to be concave, which can diverge light to achieve the shooting of close-range targets. At the same time, the edges of the first and second lenses are interlocked, which helps to reduce the size of the optical camera lens and improve the stability of the lens structure. On this basis, by setting multiple spacer elements and lens barrels and matching 0.5 < (CT5 + T56 + CT6) / (EP45 + EP56) < 1.1, the aperture of the fifth, sixth, and seventh lenses can be reduced while ensuring that the illuminance of the edge field of view does not decrease, thus helping to ensure the overall brightness of the image. This application, by controlling the fifth lens and the fourth spacer element, facilitates the control of the overall shape of the fifth lens; by controlling the sixth lens and the fifth spacer element, it facilitates the control of the overall shape of the sixth lens; and by controlling the distance between the fifth lens and the sixth lens, it can control their shape while ensuring the correction of off-axis aberrations, which is beneficial for assembly stability.

[0065] In an exemplary embodiment, the optical camera lens according to this application satisfies: 0.5 < (CT3 + T34 + CT4) / (EP34 + EP23) < 1.2, where CT3 is the center thickness of the third lens on the optical axis, T34 is the air gap between the third and fourth lenses on the optical axis, CT4 is the center thickness of the fourth lens on the optical axis, and EP34 is the distance between the image side of the third spacer element and the object side of the fourth spacer element along the optical axis. Figure 12 ), EP23 is the distance between the image side of the second spacer element and the object side of the third spacer element along the optical axis. Figure 12 Satisfying 0.5 < (CT3 + T34 + CT4) / (EP34 + EP23) < 1.2 is beneficial for controlling the ratio of the center thickness of the third and fourth lenses to the air gap between them within a reasonable range, thereby reducing the field curvature of the optical camera lens and improving the smoothness of the distortion curve of the optical camera lens. This application, by controlling the third lens and the second spacer element, facilitates the control of the overall shape of the third lens; by controlling the fourth lens and the third spacer element, it facilitates the control of the overall shape of the third lens; and by controlling the distance between the third and fourth lenses, it can control their shape while ensuring the correction of off-axis aberrations, which is beneficial for assembly stability.

[0066] In an exemplary embodiment, the optical camera lens according to this application satisfies: 25.0 < EP45 / CP5 + T45 / CT5 < 41.0, where EP45 is the distance between the image side of the fourth spacer element and the object side of the fifth spacer element along the optical axis. Figure 12 ), CP5 is the maximum thickness of the fifth spacer element ( Figure 12 T45 is the air gap between the fourth and fifth lenses on the optical axis, and CT5 is the center thickness of the fifth lens on the optical axis. Satisfying 25.0 < EP45 / CP5 + T45 / CT5 < 41.0 allows for a reasonable setting of the shapes of the fifth and sixth lenses, which is beneficial for improving the lens's performance in clear imaging at macro distances, while also enabling the lens to achieve clear imaging at infinite object distances.

[0067] In an exemplary embodiment, the optical camera lens according to this application satisfies: -2.0 < (EP56 + CP6) / SAG71 < -0.4, where EP56 is the distance between the image side of the fifth spacer element and the object side of the sixth spacer element along the optical axis. Figure 12 ), CP6 is the maximum thickness of the sixth spacer element ( Figure 12 SAG71 is the distance along the optical axis from the intersection of the object-side surface of the seventh lens and the optical axis to the vertex of the effective radius of the object-side surface of the seventh lens. Satisfying -2.0 < (EP56 + CP6) / SAG71 < -0.4 helps to rationally control the distances between the edge spacings of the fifth and sixth lenses and the sixth and seventh lenses, thereby improving the assembly stability of the fifth and sixth spacer elements, and enhancing the overall assembly stability from the fifth to the seventh lens, ultimately improving the optical performance of the lens.

[0068] In an exemplary embodiment, the optical camera lens according to this application satisfies: 1.0 < DT32 × D3s / (DT22 × D2m) < 1.5, where DT22 is the maximum effective radius of the image-side surface of the second lens, DT32 is the maximum effective radius of the image-side surface of the third lens, and D3s is the outer diameter of the object-side surface of the third spacer element. Figure 12 D2m is the outer diameter of the image-side surface of the second spacer element. Figure 12 Satisfying 1.0 < DT32 × D3s / (DT22 × D2m) < 1.5 is beneficial for controlling the aperture-to-thickness ratio of the second and third lenses within a reasonable range. This can enhance the strength of the second and third lenses and prevent them from undergoing significant deformation during assembly, thus affecting the imaging quality.

[0069] In an exemplary embodiment, the optical camera lens according to this application satisfies: -35.0 < R7 / f4 < -11.5, where f4 is the effective focal length of the fourth lens and R7 is the radius of curvature of the object-side surface of the fourth lens. Satisfying -35.0 < R7 / f4 < -11.5 facilitates the rational setting of the shape and radius of curvature of the fourth lens, thereby improving the imaging quality of the optical camera lens.

[0070] In an exemplary embodiment, the optical camera lens according to this application satisfies: 1.4 < f / EPD < 1.6 and 1.0 < (D0m - D0s) / ImgH < 1.5, where f is the total effective focal length of the optical camera lens, EPD is the entrance pupil diameter of the optical camera lens, and D0m is the outer diameter of the image-side end of the lens barrel. Figure 12 D0s is the outer diameter of the object-side end of the microscope tube. Figure 12 ImgH is half the diagonal length of the effective pixel area on the imaging plane of an optical camera lens. Satisfying 1.4 < f / EPD < 1.6 effectively controls the incident light range, contributing to improved image quality and brightness. Simultaneously, satisfying 1.0 < (D0m - D0s) / ImgH < 1.5 helps achieve miniaturization of the optical camera lens while maintaining good imaging performance.

[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 miniaturization, large image plane, good assembly stability, small step difference, low sensitivity, 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 seven lenses mentioned above. By rationally allocating the optical 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 optical camera lens can be reduced, and the manufacturability of the optical camera 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 a spacer element between adjacent lenses and designing the inner and outer diameters of the spacer element according to the optical path, stray light can be effectively blocked and eliminated, improving the imaging quality of the lens.

[0072] In the 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 seventh lens is an aspherical mirror surface. The characteristic of an aspherical lens is that its curvature changes continuously from the center to the periphery of the lens. Unlike a spherical lens, which has a constant curvature from the center to the periphery, an aspherical lens has better radius of curvature 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, sixth, and seventh lenses is an aspherical mirror surface. Optionally, both the object-side and image-side surfaces of each of the first, second, third, fourth, fifth, sixth, and seventh 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 seven lenses are described as an example in the embodiments, the optical camera lens is not limited to including seven lenses. If desired, the optical camera lens may also include other numbers of lenses.

The filter E8 has an object-side surface S15 and an image-side surface S16. Light from the object passes sequentially through surfaces S1 to S16 and is finally imaged onto the imaging surface S17.

In actual production, the specific structure and actual parameters of each spacer element can be set in any suitable manner.

[0090] In Embodiment 1, the object-side surface and image-side surface of any one of the first lens E1 to the seventh lens E7 are aspherical surfaces, and the surface shape x of each aspherical lens can be defined using, but is not limited to, the following aspherical formula:
