Description

Technical Field

[0001] The present invention relates to the technical field of optical imaging equipment, and in particular to an optical camera lens. Background Art

[0002] With the increasing use of portable electronic products such as mobile phones and tablets, the demand for camera quality is increasing, and a single camera module is no longer sufficient. Portable electronic products are often equipped with multiple camera modules to meet user needs in diverse environments. Telephoto lenses are often used in portable electronic products to achieve clear images at long distances and maintain clarity even when the image is zoomed in.

[0003] As portable electronic products such as mobile phones and tablets are gradually developing in the direction of being lighter and thinner, they also require telephoto lenses to be able to produce clear images at a longer shooting distance. The shooting distance of a telephoto lens is related to its focal length. The longer the focal length of the telephoto lens, the longer the shooting distance and the higher the shooting clarity. However, this will cause the telephoto lens to be longer in the thickness direction of the portable electronic product, and thus cannot be installed in the lightweight portable electronic product.

[0032] By incorporating a prism into the optical camera lens, light is redirected from the direction extending from the first optical axis to the direction extending from the second optical axis, changing the light propagation path. This helps reduce the length of the optical camera lens in the direction extending from the first optical axis, facilitating miniaturization of the optical camera lens and reducing its length relative to the thickness of the mobile phone. This, in turn, facilitates its integration into lightweight portable electronic products, facilitating the trend toward thinner and lighter mobile phones with higher image quality. Furthermore, the rational distribution of the optical power of the first, second, third, and fifth lenses helps balance aberrations and enhance the imaging quality of the optical camera lens. By distributing the focal lengths of the first through fourth lenses, the combined focal length f234 of the second, third, and fourth lenses has only a relatively large absolute value, while the second and third lenses have relatively small focal lengths. This facilitates the optical camera lens's telephoto characteristics, enabling clear imaging at long distances. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0048] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] 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 ordinary technicians in the technical field to which this application belongs.

[0050] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0051] It should be noted that in this specification, the terms "first," "second," "third," etc., are used solely to distinguish one feature from another and do not limit the features. Thus, the first lens discussed below could also be referred to as the second lens or the third lens without departing from the teachings of this application.

[0052] In the drawings, the thickness, size, and shape of the lenses are slightly exaggerated for ease of illustration. Specifically, the shapes of the spherical and aspherical surfaces shown in the drawings are provided by way of example. That is, the shapes of the spherical and aspherical surfaces are not limited to those shown in the drawings. The drawings are for illustration only and are not drawn strictly to scale.

[0053] In this article, the paraxial area refers to the area near the optical axis. If the lens surface is convex and the position of the convex surface is not defined, it means that the lens surface is convex at least in the paraxial area; if the lens surface is concave and the position of the concave surface is not defined, it means that the lens surface is concave at least in the paraxial area. The judgment of the surface shape in the paraxial area can be based on the judgment method of ordinary knowledge in this field, and the positive and negative R value (R refers to the radius of curvature of the paraxial area, usually refers to the R value on the lens database (lens data) in the optical software) is used to judge the convexity and concavity. For the object side, when the R value is positive, it is judged to be convex, and when the R value is negative, it is judged to be concave; for the image side, when the R value is positive, it is judged to be concave, and when the R value is negative, it is judged to be convex.

[0054] In this application, the object-side surface refers to the light incident side surface, and the image-side surface refers to the light exit side surface.

[0055] In order to solve the problem in the prior art that miniaturization and long-distance clear imaging cannot be achieved at the same time, the present invention provides an optical camera lens.

[0056] Example 1

[0057] like Figures 1 to 30 As shown, the optical camera lens comprises, from the object side to the image side, a first lens, a prism, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens, wherein the first lens has positive focal power; the prism has an incident surface, a reflecting surface and an exit surface, and the second lens has negative focal power; the third lens has positive focal power, the object side surface of the third lens is convex, and the image side surface of the third lens is concave; the fourth lens has focal power; the fifth lens has negative focal power; the sixth lens has focal power; the prism is located between the first lens and the second lens, and the prism is configured so that light emitted from the first lens enters the prism through the incident surface along the direction of the first optical axis, is reflected by the reflecting surface, and is emitted from the second lens through the exit surface along the direction of the second optical axis, and the first optical axis is perpendicular to the second optical axis; wherein the combined focal length f234 of the second lens, the effective focal length f2 of the second lens, and the effective focal length f3 of the third lens satisfy the following conditions: -22 <f234 / (f2+f3)<-5。

[0058] By arranging a prism in the optical camera lens, the light is redirected from the extension direction of the first optical axis to the extension direction of the second optical axis, changing the propagation path of the light. This helps reduce the length of the optical camera lens in the extension direction of the first optical axis, facilitating the miniaturization of the optical camera lens. Furthermore, it is beneficial for the optical camera lens to be incorporated into thin and light portable electronic products, enabling mobile phones to develop towards the direction of being thinner, lighter, and having higher image quality. At the same time, the reasonable distribution of the optical powers of the first lens, second lens, third lens, and fifth lens helps balance aberrations and improve the imaging quality of the optical camera lens. Through the distribution of the focal lengths of the first lens to the fourth lens, the combined focal length f234 of the second lens, third lens, and fourth lens only has a relatively large absolute value of the focal length, while the second lens and the third lens are assigned smaller focal length values, which is conducive to the optical camera lens achieving the characteristics of a long focal length and thus enabling clear imaging at a long distance.

[0059] Preferably, the combined focal length f234 of the second lens, third lens, and fourth lens, the effective focal length f2 of the second lens, and the effective focal length of the third lens satisfy: -21.7 < f234 / (f2 + f3) < -5.5.

[0060] In this embodiment, the relative F-number Fno of the optical camera lens, the air gap T23 between the second lens and the third lens on the optical axis, and the air gap T45 between the fourth lens and the fifth lens on the optical axis satisfy: 3 < T45 / T23 * Fno < 8. By controlling T45 / T23 * Fno within a reasonable range, the optical camera lens has a large aperture, which is beneficial for increasing the amount of light entering and achieving clear imaging in a dark environment, expanding the application scenarios of the optical camera lens. At the same time, the reasonable distribution of the distances between the second lens and the third lens and between the fourth lens and the fifth lens helps control the field curvature of each field of view within a small range, facilitating clear imaging of the optical camera lens. The optical camera lens in this application has the characteristics of both a large focal length and a large aperture, resulting in a better background虚化 effect. Preferably, 3.1 < T45 / T23 * Fno < 7.9. <所提及的“虚化”在光学领域一般指背景虚化效果,英文可表述为“background虚化 effect”,这里的“虚化”可能是特定术语,原文未给出准确英文表述,所以保留原文。

[0061] In this embodiment, the curvature radius R7 of the object side surface of the fourth lens and the curvature radius R8 of the image side surface of the fourth lens satisfy: 10 < (R7 + R8) / (R7 - R8) < 25. By restricting (R7 + R8) / (R7 - R8) within a reasonable range, it is beneficial to control the shape of the fourth lens within a reasonable range, reducing the coma of the on-axis field of view and the off-axis field of view, thereby enabling the optical camera lens to have good imaging quality. At the same time, it is conducive to the manufacturing of the fourth lens and ensures the yield rate of the fourth lens. Preferably, 10.5 < (R7 + R8) / (R7 - R8) < 24.9.

[0062] In this embodiment, the effective focal length f1 of the first lens and the distance BFL from the image side of the last lens of the optical imaging lens to the imaging surface of the optical imaging lens on the optical axis satisfy: 2 < f1 / BFL < 5. By controlling f1 / BFL within a reasonable range, the optical imaging lens has a large back focal length, and when the moving range of the imaging surface of the optical imaging lens is large, a good imaging effect can still be achieved. Preferably, 2.5 < f1 / BFL < 4.8.

[0063] In this embodiment, the distance TTL from the object side of the first lens to the imaging surface of the optical imaging lens on the optical axis, the central thickness CT6 of the sixth lens on the optical axis, and the distance BFL from the image side of the last lens of the optical imaging lens to the imaging surface of the optical imaging lens on the optical axis satisfy: 3.2 < TTL / (BFL - CT6) < 5.2. By controlling TTL / (BFL - CT6) within a reasonable range, it is beneficial to meet the requirements of the module end structure, facilitate the stable assembly of the optical imaging lens, and ensure the imaging quality. Preferably, 3.4 < TTL / (BFL - CT6) < 5.1.

[0064] In this embodiment, the radius of curvature R1 of the object side of the first lens and the radius of curvature R3 of the object side of the second lens satisfy: 9 < (R1 + R3) / (R1 - R3) < 17. By controlling the radius of curvature of the object side of the first lens and the radius of curvature of the object side of the second lens, the total deflection angle of the object side and the image side of the second lens at the edge field can be reasonably controlled within a reasonable range, and the sensitivity of the optical imaging lens can be effectively reduced. Preferably, 9.2 < (R1 + R3) / (R1 - R3) < 16.6.

[0065] In this embodiment, the effective focal length f of the optical imaging lens, the effective focal length f3 of the third lens, and the effective focal length f5 of the fifth lens satisfy: 2 < |f / f3| + |f / f5| < 4. By controlling |f / f3| + |f / f5| within a reasonable range, a reasonable positive third-order spherical aberration and negative fifth-order spherical aberration can be contributed, balancing the negative third-order spherical aberration and positive fifth-order spherical aberration generated by the third lens and the fifth lens, so that the optical imaging lens has a small spherical aberration and ensures good imaging quality in the axial field. Preferably, 2.1 < |f / f3| + |f / f5| < 3.9.

[0066] In this embodiment, the effective focal length f of the optical camera lens, the effective focal length f3 of the third lens element, and the effective focal length f5 of the fifth lens element satisfy the following relationship: 1 < |f1 / f3| - |f1 / f5| < 5. By controlling |f1 / f3| - |f1 / f5| within a reasonable range, the aberrations generated by the first, third, and fifth lenses are balanced, thereby improving the imaging quality of the optical camera lens. Preferably, 1.2 < |f1 / f3| - |f1 / f5| < 4.8.

[0067] In this embodiment, the combined focal length f456 of the fourth, fifth, and sixth lenses and the effective focal length f1 of the first lens satisfy the following relationship: 0.5 < |f456 / f1| < 3.5. By controlling |f456 / f1| within a reasonable range, the optical power of the front and rear optical systems is properly distributed. The negative spherical aberration generated by f1 is balanced with the positive spherical aberration generated by f456, achieving excellent imaging results and improving the imaging quality of the optical camera lens. Preferably, 0.6 < |f456 / f1| < 3.3.

[0068] In this embodiment, the combined focal length f456 of the fourth, fifth, and sixth lenses and the effective focal length f of the optical camera lens satisfy the following relationship: 1 < |f456 / f| < 7. By controlling |f456 / f| within a reasonable range and properly allocating the proportion of the combined focal length of the fourth, fifth, and sixth lenses to the total focal length, this helps balance high-order spherical aberrations generated by the optical camera lens and improves imaging quality. Preferably, 1.2 < |f456 / f| < 6.8.

[0069] In this embodiment, the maximum effective radius DT11 of the object-side surface of the first lens, the maximum effective radius DT12 of the image-side surface of the first lens, the maximum effective radius DT21 of the object-side surface of the second lens, and the maximum effective radius DT22 of the image-side surface of the second lens satisfy the following relationship: 3<(DT11+DT21) / (DT12-DT22)<4. By constraining the maximum effective radii of the object-side surface and image-side surface of the first lens and the maximum effective radii of the object-side surface and image-side surface of the second lens to a smaller range, the radial size of the optical camera lens is reduced, facilitating its assembly into ultra-thin mobile phones. Preferably, 3.05<(DT11+DT21) / (DT12-DT22)<4.

[0070] In this embodiment, the center thickness CT4 of the fourth lens element, the center thickness CT5 of the fifth lens element, the center thickness CT6 of the sixth lens element, the air spacing T45 between the fourth and fifth lenses, and the air spacing T56 between the fifth and sixth lenses satisfy the following: 2.5 < (CT4 + CT5 + CT6) / (T45 + T56) < 4.2. Limiting (CT4 + CT5 + CT6) / (T45 + T56) to a reasonable range helps control the field curvature contribution of each field of view within a reasonable range, thereby improving the imaging quality of the optical camera lens. Preferably, 2.58 < (CT4 + CT5 + CT6) / (T45 + T56) < 4.12.

[0071] In this embodiment, the object-side surface of the fourth lens is convex, and the image-side surface of the fourth lens is concave. By setting the object-side surface of the fourth lens to be convex and the image-side surface to be concave, the fourth lens has a relatively large positive focal power, which is beneficial for increasing the overall focal length of the optical camera lens and facilitating long-distance photography.

[0072] Example 2

[0073] like Figures 1 to 30 As shown, the optical camera lens includes a first lens, a prism, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens, the first lens has positive focal power; the prism has an incident surface, a reflecting surface and an exit surface, the second lens has negative focal power; the third lens has positive focal power, the object side surface of the third lens is convex, and the image side surface of the third lens is concave; the fourth lens has optical focal power; the fifth lens has negative optical focal power; the sixth lens has optical focal power; the prism is located between the first lens and the second lens, and the prism is configured so that light emitted from the first lens enters the prism through the incident surface along the direction of the first optical axis, is reflected by the reflecting surface, and is emitted into the second lens through the exit surface along the direction of the second optical axis, and the first optical axis is perpendicular to the second optical axis; wherein the combined focal length f456 of the fourth lens, the fifth lens and the sixth lens and the effective focal length f of the optical camera lens satisfy the following relationship: 1<|f456 / f|<7.

[0074] By setting a prism in the optical camera lens, the light is redirected from the extension direction of the first optical axis to the extension direction of the second optical axis, changing the propagation path of the light. This helps reduce the length of the optical camera lens in the extension direction of the first optical axis, facilitating the miniaturization of the optical camera lens. Consequently, it is beneficial for the optical camera lens to be incorporated into thin and light portable electronic products, enabling mobile phones to develop towards the direction of thinness, lightness, and high image quality. At the same time, the reasonable distribution of the optical powers of the first lens, second lens, third lens, and fifth lens helps balance aberrations and improve the imaging quality of the optical camera lens. By controlling |f456 / f| within a reasonable range and rationally distributing the combined focal length of the fourth lens, fifth lens, and sixth lens as a proportion of the total focal length, it is conducive to balancing the high-order spherical aberration generated by the optical camera lens and enhancing the imaging quality of the optical camera lens.

[0075] Preferably, the combined focal length f456 of the fourth lens, fifth lens, and sixth lens and the effective focal length f of the optical camera lens satisfy: 1.2 < |f456 / f| < 6.8.

[0076] In this embodiment, the relative F-number Fno of the optical camera lens, the air gap T23 between the second lens and the third lens on the optical axis, and the air gap T45 between the fourth lens and the fifth lens on the optical axis satisfy: 3 < T45 / T23 * Fno < 8. By controlling T45 / T23 * Fno within a reasonable range, the optical camera lens has a large aperture, which is beneficial for increasing the light intake, achieving clear imaging in low-light environments, and expanding the application scenarios of the optical camera lens. At the same time, the reasonable distribution of the distances between the second lens and the third lens and between the fourth lens and the fifth lens helps control the field curvature of each field within a small range, facilitating clear imaging of the optical camera lens. The optical camera lens in this application features both a large focal length and a large aperture, resulting in a better background虚化 effect. Preferably, 3.1 < T45 / T23 * Fno < 7.9.

[0077] In this embodiment, the curvature radius R7 of the object side of the fourth lens and the curvature radius R8 of the image side of the fourth lens satisfy: 10 < (R7 + R8) / (R7 - R8) < 25. By restricting (R7 + R8) / (R7 - R8) within a reasonable range, it is beneficial to control the shape of the fourth lens within a reasonable range, reducing the coma of the on-axis and off-axis fields. Consequently, the optical camera lens has good imaging quality. At the same time, it is conducive to the manufacturing of the fourth lens and ensures a high yield rate of the fourth lens. Preferably, 10.5 < (R7 + R8) / (R7 - R8) < 24.9.

[0078] In this embodiment, the effective focal length f1 of the first lens and the distance BFL from the image side of the last lens of the optical camera lens to the imaging surface of the optical camera lens on the optical axis satisfy: 2 < f1 / BFL < 5. By controlling f1 / BFL within a reasonable range, the optical camera lens has a large back focal length, and when the imaging surface of the optical camera lens has a large moving range, a good imaging effect can still be achieved. Preferably, 2.5 < f1 / BFL < 4.8.

[0079] In this embodiment, the distance TTL from the object side of the first lens to the imaging surface of the optical camera lens on the optical axis, the central thickness CT6 of the sixth lens on the optical axis, and the distance BFL from the image side of the last lens of the optical camera lens to the imaging surface of the optical camera lens on the optical axis satisfy: 3.2 < TTL / (BFL - CT6) < 5.2. By controlling TTL / (BFL - CT6) within a reasonable range, it is beneficial to meet the requirements of the module end structure, is beneficial to the stable assembly of the optical camera lens, and ensures the imaging quality. Preferably, 3.4 < TTL / (BFL - CT6) < 5.1.

[0080] In this embodiment, the radius of curvature R1 of the object side of the first lens and the radius of curvature R ^ 3 of the object side of the second lens satisfy: 9 < (R1 + R3) / (R1 - R3) < 17. By controlling the radius of curvature of the object side of the first lens and the radius of curvature of the object side of the second lens, the total deflection angle of the object side and the image side of the second lens at the edge field can be reasonably controlled within a reasonable range, and the sensitivity of the optical camera lens can be effectively reduced. Preferably, 9.2 < (R1 + R3) / (R1 - R3) < 16.6.

[0081] In this embodiment, the effective focal length f of the optical camera lens, the effective focal length f3 of the third lens, and the effective focal length f5 of the fifth lens satisfy: 2 < |f / f3| + |f / f5| < 4. By controlling |f / f3| + |f / f5| within a reasonable range, reasonable positive third-order spherical aberration and negative fifth-order spherical aberration can be contributed, the negative third-order spherical aberration and positive fifth-order spherical aberration generated by the third lens and the fifth lens can be balanced, and the optical camera lens has a small spherical aberration, ensuring good imaging quality in the axial field. Preferably, 2.1 < |f / f3| + |f / f5| < 3.9.

[0082] In this embodiment, the effective focal length f of the optical camera lens, the effective focal length f3 of the third lens element, and the effective focal length f5 of the fifth lens element satisfy the following relationship: 1 < |f1 / f3| - |f1 / f5| < 5. By controlling |f1 / f3| - |f1 / f5| within a reasonable range, the aberrations generated by the first, third, and fifth lenses are balanced, thereby improving the imaging quality of the optical camera lens. Preferably, 1.2 < |f1 / f3| - |f1 / f5| < 4.8.

[0083] In this embodiment, the combined focal length f456 of the fourth, fifth, and sixth lenses and the effective focal length f1 of the first lens satisfy the following relationship: 0.5 < |f456 / f1| < 3.5. By controlling |f456 / f1| within a reasonable range, the optical power of the front and rear optical systems is properly distributed. The negative spherical aberration generated by f1 is balanced with the positive spherical aberration generated by f456, achieving excellent imaging results and improving the imaging quality of the optical camera lens. Preferably, 0.6 < |f456 / f1| < 3.3.

[0084] In this embodiment, the maximum effective radius DT11 of the object-side surface of the first lens, the maximum effective radius DT12 of the image-side surface of the first lens, the maximum effective radius DT21 of the object-side surface of the second lens, and the maximum effective radius DT22 of the image-side surface of the second lens satisfy the following relationship: 3<(DT11+DT21) / (DT12-DT22)<4. By constraining the maximum effective radii of the object-side surface and image-side surface of the first lens and the maximum effective radii of the object-side surface and image-side surface of the second lens to a smaller range, the radial size of the optical camera lens is reduced, facilitating its assembly into ultra-thin mobile phones. Preferably, 3.05<(DT11+DT21) / (DT12-DT22)<4.

[0085] In this embodiment, the center thickness CT4 of the fourth lens element, the center thickness CT5 of the fifth lens element, the center thickness CT6 of the sixth lens element, the air spacing T45 between the fourth and fifth lenses, and the air spacing T56 between the fifth and sixth lenses satisfy the following: 2.5 < (CT4 + CT5 + CT6) / (T45 + T56) < 4.2. Limiting (CT4 + CT5 + CT6) / (T45 + T56) to a reasonable range helps control the field curvature contribution of each field of view within a reasonable range, thereby improving the imaging quality of the optical camera lens. Preferably, 2.58 < (CT4 + CT5 + CT6) / (T45 + T56) < 4.12.

[0086] In this embodiment, the object-side surface of the fourth lens is convex, and the image-side surface of the fourth lens is concave. By setting the object-side surface of the fourth lens to be convex and the image-side surface to be concave, the fourth lens has a relatively large positive focal power, which is beneficial for increasing the overall focal length of the optical camera lens and facilitating long-distance photography.

[0087] Optionally, the optical camera lens may further include a filter for correcting color deviation and / or a protective glass for protecting a photosensitive element located on the imaging surface.

[0088] The optical camera lens in this application can use multiple lenses, such as the six lenses described above. By properly allocating the optical power, surface shape, center thickness of each lens, and the on-axis distance between lenses, the imaging quality of the optical camera lens can be effectively improved, the sensitivity of the optical camera lens can be reduced, and the processability of the optical camera lens can be improved, making the optical camera lens more convenient for production and processing and suitable for portable electronic devices such as smartphones.

[0089] In this application, at least one of the lens surfaces is an aspheric surface. Aspheric lenses are characterized by a continuously varying curvature from the center to the periphery. Unlike spherical lenses, which have a constant curvature from the center to the periphery, aspheric lenses have a more optimized curvature radius, offering advantages in reducing distortion and astigmatism. The use of aspheric lenses can minimize aberrations that occur during imaging, thereby improving image quality.

[0090] However, those skilled in the art will appreciate that the number of lenses comprising the optical camera lens may be varied to achieve the various results and advantages described herein without departing from the claimed technical solutions. For example, while the embodiments describe an optical camera lens using six lenses as an example, the optical camera lens is not limited to six lenses. If desired, the optical camera lens may include other numbers of lenses.

[0091] The following further describes examples of specific surface shapes and parameters of the optical camera lens applicable to the above-mentioned embodiments with reference to the accompanying drawings.

[0101] In Example 1, the object-side surface and the image-side surface of any lens from the first lens E1 to the sixth lens E6 are both aspherical surfaces. The surface shape of each aspherical lens can be defined by, but is not limited to, the following aspherical surface formula:

[0102]

[0103] Where x is the distance vector from the vertex of the aspheric surface at a height h along the optical axis; c is the paraxial curvature of the aspheric surface, c = 1 / R (i.e., paraxial curvature c is the reciprocal of the radius of curvature R in Table 1 above); k is the conic coefficient; and Ai is the correction coefficient for the i-th order of the aspheric surface. Table 2 below lists the higher-order coefficients A4, A6, A8, A10, A12, A14, A16, A18, and A20 that can be used for each aspheric mirror surface P1-P12 in Example 1.

[0151] Example 5

[0152] like Figures 21 to 25 As shown, the optical camera lens of Example 5 of the present application is described. Figure 21 The structure diagram of the optical camera lens of Example 5 is shown. For the sake of brevity, similar descriptions of some examples are omitted.

The second lens E2 has negative focal power, with its object-side surface P3 being convex, and its image-side surface P4 being concave. The third lens E3 has positive focal power, with its object-side surface P5 being convex, and its image-side surface P6 being convex. The fourth lens E4 has positive focal power, with its object-side surface P7 being convex, and its image-side surface P8 being concave. The fifth lens E5 has negative focal power, with its object-side surface P9 being concave, and its image-side surface P10 being convex. The sixth lens E6 has negative focal power, with its object-side surface P11 being concave, and its image-side surface P12 being concave. The filter E7 has an object-side surface P13 and an image-side surface P14. Light from an object passes through the surfaces P1 to P14 in sequence and is finally imaged on the imaging surface P15 .

[0155] In this example, the half image height ImgH of the optical camera lens is 3.93 mm, and the total length TTL of the optical camera lens is 23.35 mm.
