[0040] In order to better understand the present application, various aspects of the present application are described in detail with reference to the accompanying drawings. It should be understood that these detailed descriptions are only descriptions of exemplary embodiments of the present application and are not intended to limit the scope of the present application in any way.

[0041] 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.

[0042] In this article, the paraxial region refers to the area near the optical axis. If a lens surface is convex and the location of the convex surface is undefined, it means that the lens surface is convex at least in the paraxial region. If a lens surface is concave and the location of the concave surface is undefined, it means that the lens surface is concave at least in the paraxial region. The surface of each lens closest to the subject is called the object-side surface of the lens, and the surface of each lens closest to the imaging plane is called the image-side surface of the lens.

[0043] It should also be understood that the terms "include," "comprising," "having," "including," and / or "comprising," when used in this specification, indicate the presence of the stated features, elements, and / or components, but do not preclude the presence or addition of one or more other features, elements, components, and / or combinations thereof. It should be noted that in this specification, the terms "first," "second," "third," and so on, are used only to distinguish one feature from another, and do not represent any limitation on the features.

[0044] Unless otherwise defined, all terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. Terms should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology and will not be interpreted in an idealized or overly formal sense unless expressly defined as such herein.

[0045] 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 application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] The first aspect of the present application provides an optical imaging lens, which may include a prism for changing the optical path direction. For example, the prism is configured such that light incident on the prism along the direction of the Y optical axis is reflected and exits the prism along the direction of the X optical axis, where the Y optical axis is perpendicular to the X optical axis.

[0047] The optical imaging lens may further include a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. Among them, the first lens is located on the Y optical axis and is disposed between the object side and the prism. The second lens, the third lens, the fourth lens, the fifth lens, and the sixth lens are arranged in sequence along the X optical axis from the prism to the image side. The prism may have an incident surface, a reflection surface, and an exit surface. The light emitted by the first lens enters the prism through the incident surface along the direction of the Y optical axis, is reflected by the reflection surface inside the prism, and then exits the prism through the exit surface along the direction of the X optical axis and enters the second lens. There may be air gaps between the first lens and the prism, between the prism and the second lens, and between adjacent lenses. The number of lenses with refractive power in the optical imaging lens is six.

[0048] By using the prism, the light rays emitted from the first lens can be refracted by 90°, so that the direction of the light rays emitted from the first lens is substantially perpendicular to the arrangement direction of the multiple lenses behind, thereby using the length space of the mobile phone as the zoom space of the optical imaging lens and avoiding the limitation of the focal length of the optical imaging lens by the body thickness. The component formed by combining the first lens and the prism can be called an anti-shake component.

[0049] In an exemplary embodiment, the first lens may have positive refractive power. The object side surface of the first lens may be convex, and the image side surface may be concave. The second lens may have negative refractive power. The object side surface of the second lens may be concave, and the image side surface may be convex. The third lens may have positive refractive power. The object side surface of the third lens may be convex, and the image side surface may be concave. The fourth lens may have refractive power. The fifth lens may have positive refractive power. The object side surface of the fifth lens may be convex, and the image side surface may be convex. The sixth lens may have negative refractive power. The object side surface of the sixth lens may be concave. Reasonably configuring the refractive power and surface type of each lens can enable the optical imaging lens to achieve the characteristics of a long focal length.

[0050] In an exemplary embodiment, the total effective focal length f of the optical imaging lens may satisfy: 14 mm < f < 21 mm. Reasonably configuring the total effective focal length of the optical imaging lens can enable the optical imaging lens to achieve the characteristics of a long focal length.

[0051] In an exemplary embodiment, half of the maximum field angle of view Semi-FOV of the optical imaging lens may satisfy: 9° < Semi-FOV < 20°. Reasonably configuring half of the maximum field angle of view of the optical imaging lens can enable the optical imaging lens to achieve the characteristics of a long focal length.

[0052] In an exemplary embodiment, the distance G2 on the X-ray axis from the reflecting surface of the prism to the imaging surface of the optical imaging lens and the total effective focal length f of the optical imaging lens may satisfy: 1.1 < G2 / f < 1.7; the effective focal length f3 of the third lens and the effective focal length f6 of the sixth lens may satisfy: -1.6 < f3 / f6 < -1.0; the radius of curvature R4 of the image side of the second lens and the radius of curvature R6 of the image side of the third lens may satisfy: -4.3 < (R4 - R6) / (R4 + R6) < -3.0; the effective focal length f1 of the first lens and the total effective focal length f of the optical imaging lens may satisfy: 2.0 < f1 / f < 2.8; and the distance PL on the Y-ray axis from the image side of the first lens to the incident surface of the prism may satisfy: 1.0 mm < PL < 1.9 mm. Reasonably configuring the radii of curvature of the image sides of the second lens and the third lens, and restricting the ratio of the effective focal length of the third lens to the effective focal length of the sixth lens and the ratio of the distance on the X-ray axis from the reflecting surface of the prism to the imaging surface of the optical imaging lens to the total effective focal length of the optical imaging lens is conducive to adjusting the angle of paraxial rays and balancing aberrations, thereby ensuring that the optical imaging lens obtains good imaging quality. In addition, by reasonably configuring the distance on the Y-ray axis from the image side of the first lens to the incident surface of the prism and the ratio of the effective focal length of the first lens to the total effective focal length of the optical imaging lens, the sensitivity of the tilt of the first lens to the imaging performance can be reduced, and at the same time, the deflection effect of the prism on the light rays when deflecting the optical path can be minimized. When the first lens and the prism are taken as a whole, the eccentricity and sensitivity can be reduced.

[0053] In an exemplary embodiment, the effective focal length f1 of the first lens and the effective focal length f2 of the second lens may satisfy: -2.8 < f1 / f2 < -2.1. Reasonably configuring the ratio of the effective focal length of the first lens to the effective focal length of the second lens can adjust the angle of paraxial rays when the first lens is tilted, and make the combination of the first lens and the prism have a good anti-shake effect.

[0054] In an exemplary embodiment, the effective focal length f1 of the first lens and the distance G1 on the Y-ray axis from the object side of the first lens to the reflecting surface of the prism may satisfy: 4.9 < f1 / G1 < 7.0. Reasonably configuring the ratio of the effective focal length of the first lens to the distance on the Y-ray axis from the object side of the first lens to the reflecting surface of the prism can control the gap between the first lens and the prism while reducing the tilt sensitivity of the combination of the first lens and the prism, ensuring that the anti-shake component does not affect the imaging resolution during OIS anti-shake compensation.

[0055] In an exemplary embodiment, the distance G1 from the object side surface of the first lens to the reflection surface of the prism on the Y optical axis, the distance G2 from the reflection surface of the prism to the imaging surface on the X optical axis, and the total effective focal length f of the optical imaging lens may satisfy: 1.6 < (G1 + G2) / f < 2.0. By reasonably configuring the ratio of the overall lengths of the optical imaging lens on the Y optical axis and the X optical axis to the total effective focal length of the optical imaging lens, the tilt sensitivity after combining the first lens and the prism can be reduced, and at the same time, it is ensured that when the anti-shake component performs OIS anti-shake compensation, as long as the tilt angle is small enough, the influence amount on the image caused by anti-shake can be compensated.

[0056] In an exemplary embodiment, the distance G2 from the reflection surface of the prism to the imaging surface on the X optical axis, the distance PR from the exit surface of the prism to the object side surface of the second lens on the X optical axis, and the sum PT of the central thicknesses of the prism on the Y optical axis and the X optical axis and the distance BFL from the image side surface of the sixth lens to the imaging surface on the X optical axis may satisfy: 1.8 < (G2 - PR - PT) / BFL < 2.5. By controlling the above conditional expression, the gaps between the prism and the first lens, the gaps between the prism and the second lens, and the back focal length of the optical imaging lens can be restricted, the tolerance sensitivity of the anti-shake component can be reduced, and it is ensured that the optical imaging lens still has a high resolution when the anti-shake component is tilted or eccentric.

[0057] In an exemplary embodiment, the distance PL from the image side surface of the first lens to the incident surface of the prism on the Y optical axis, the distance PR from the exit surface of the prism to the object side surface of the second lens on the X optical axis, and the sum PT of the central thicknesses of the prism on the Y optical axis and the X optical axis may satisfy: 0.1 < (PL + PR) / PT < 1.0. By controlling the above conditional expression, the gaps between the prism and the first lens, the gaps between the prism and the second lens, and the central thickness of the prism can be restricted, the ghost images caused by internal reflection in the prism can be effectively improved, and the energy intensity of the ghost images in the relevant part of the prism can be greatly reduced.

[0058] In an exemplary embodiment, the effective focal length f5 of the fifth lens and the effective focal length f6 of the sixth lens may satisfy: -1.1 < f5 / f6 < -0.7. By reasonably configuring the ratio of the effective focal length of the fifth lens to the effective focal length of the sixth lens, the main ray angle can be effectively adjusted by using the fifth lens and the sixth lens, and it is ensured that the optical imaging lens is not prone to image color cast problems during use.

[0059] In an exemplary embodiment, the central thickness CT4 of the fourth lens on the X optical axis, the central thickness CT5 of the fifth lens on the X optical axis, and the effective focal length f5 of the fifth lens may satisfy: 3.5 mm < f5 / (CT5 / CT4) < 5.5 mm. By controlling the above conditional expression, the fourth lens and the fifth lens can have reasonable central thicknesses, meet the requirements of the production and processing technology, and ensure that the optical imaging lens has a good production yield.

[0060] In an exemplary embodiment, the radius of curvature R5 of the object side surface of the third lens, the radius of curvature R6 of the image side surface of the third lens, and the effective focal length f3 of the third lens may satisfy: 0.8 < (R5 + R6) / f3 < 1.3. Reasonably configuring the ratio of the sum of the radii of curvature of the object side surface and the image side surface of the third lens to the effective focal length of the third lens can enable the optical imaging lens to have a sufficiently small longitudinal chromatic aberration and ensure that the optical imaging lens is not prone to phenomena such as purple edges and yellow edges during shooting.

[0061] In an exemplary embodiment, the effective focal length f2 of the second lens, the effective focal length f3 of the third lens, the central thickness CT2 of the second lens on the X optical axis, and the central thickness CT3 of the third lens on the X optical axis may satisfy: -2.2 < (f3 + f2) / (CT2 + CT3) < -0.7. Reasonably configuring the ratio of the sum of the effective focal lengths of the second lens and the third lens to the sum of the central thicknesses of the second lens and the third lens can constrain the overall shape and thickness of the second lens and the third lens, ensure that the optical imaging lens has sufficient strength, and avoid problems such as deformation and breakage of the second lens and the third lens under strict reliability conditions.

[0062] In an exemplary embodiment, the radius of curvature R6 of the image side surface of the third lens, the radius of curvature R10 of the image side surface of the fifth lens, the central thickness CT3 of the third lens on the X optical axis, and the central thickness CT6 of the sixth lens on the X optical axis may satisfy: -0.2 < R6 / R10 + CT3 / CT6 < 0.5. By controlling the ratio of the radii of curvature of the image side surfaces of the third lens and the fifth lens and the ratio of the central thicknesses of the third lens and the sixth lens, and constraining the sum of the two within a reasonable range, the lateral chromatic aberration and the difference between long and short waves of the optical imaging lens can be at a relatively small level.

[0063] In an exemplary embodiment, the axial distance SAG21 between the intersection of the object side surface of the second lens and the X optical axis and the vertex of the maximum effective semi-aperture of the object side surface of the second lens, the axial distance SAG22 between the intersection of the image side surface of the second lens and the X optical axis and the vertex of the maximum effective semi-aperture of the image side surface of the second lens, and the central thickness CT2 of the second lens on the X optical axis may satisfy: -1.7 < (SAG21 + SAG22) / CT2 < -1.0. Reasonably configuring the ratio of the sum of the sag heights of the object side surface and the image side surface of the second lens to the central thickness of the second lens can constrain the bending and shape of the effective diameter part of the second lens, and enable the second lens to effectively receive all the light rays in the prism deflection optical path, ensuring that the relative brightness of the optical imaging lens is not affected.

[0064] In an exemplary embodiment, the axial distance SAG21 between the intersection of the object side surface of the second lens and the X-ray axis and the vertex of the maximum effective semi-aperture of the object side surface of the second lens and the axial distance SAG61 between the intersection of the object side surface of the sixth lens and the X-ray axis and the vertex of the maximum effective semi-aperture of the object side surface of the sixth lens may satisfy: 0.8 < SAG21 / SAG61 < 2.0. Reasonably configuring the ratio of the sagittal heights of the object side surfaces of the second lens and the sixth lens can make the light angle of the second lens within a certain range, reduce the eccentricity sensitivity of the second lens, and meet the requirements of better manufacturing.

[0065] In an exemplary embodiment, the radius of curvature R4 of the image side surface of the second lens, the radius of curvature R5 of the object side surface of the third lens, and the radius of curvature R6 of the image side surface of the third lens may satisfy: -3.0 < (R5 + R6) / R4 < -2.2. Reasonably configuring the ratio of the sum of the radii of curvature of the object side surface and the image side surface of the third lens to the radius of curvature of the image side surface of the second lens can make the optical imaging lens have small distortion, ensure that there is extremely small picture distortion when the optical imaging lens takes pictures of people, and improve the shooting experience.

[0066] In an exemplary embodiment, the radius of curvature R3 of the object side surface of the second lens, the radius of curvature R4 of the image side surface of the second lens, the Abbe number V2 of the second lens, and the Abbe number V4 of the fourth lens may satisfy: 1.7 < |R3 / R4 × (V2 - V4)| < 2.3. By constraining the ratio of the radii of curvature of the object side surface and the image side surface of the second lens and the difference in Abbe numbers between the second lens and the fourth lens, and constraining the product of the two within a reasonable range, it can ensure that there is good chromatic aberration at the edge positions of the imaging, the chromatic aberration under the entire picture is small, and the problem of poor color fringes is avoided.

[0067] In an exemplary embodiment, the effective focal length f2 of the second lens and the effective focal length f3 of the third lens may satisfy: -2.0 < f2 / f3 < -1.2. Reasonably configuring the ratio of the effective focal length of the second lens to the effective focal length of the third lens is beneficial to adjusting the angle of paraxial light, balancing aberrations, and improving the imaging quality of the optical imaging lens.

[0068] In an exemplary embodiment, the optical imaging lens may further include an aperture. The aperture may be disposed between the prism and the second lens.

[0069] The optical imaging lens according to the above embodiment of the present application may employ a prism and multiple lenses, such as the six lenses described above. By reasonably allocating optical parameters such as the refractive power and surface shape of each lens, the central thickness of the prism and each lens, and the axial distance between the prism and each lens, the tilt sensitivity after combining the first lens and the prism can be reduced, and the long focal length characteristic of the optical imaging lens can be achieved, improving the imaging quality and production yield of the optical imaging lens.

[0070] In an embodiment of the present application, at least one of the surfaces of each of the second lens to the sixth lens is an aspherical surface. The characteristic of an aspherical lens is that the curvature changes continuously from the center of the lens to the periphery of the lens. Different from a spherical lens with a constant curvature from the center of the lens to the periphery of the lens, an aspherical lens has better curvature radius characteristics and has the advantages of improving distortion aberration and improving astigmatism aberration. After using an aspherical lens, it is possible to eliminate the aberration that appears during imaging as much as possible, thereby improving the imaging quality.

[0071] However, those skilled in the art should understand that without departing from the technical solutions claimed in the present application, the number of lenses constituting the optical imaging lens can be changed to obtain the various results and advantages described in this specification.

[0072] A second aspect of the present application provides such an optical imaging lens. The optical imaging lens may include a prism configured such that light incident on the prism in the direction of the Y optical axis exits the prism in the direction of the X optical axis after reflection, where the Y optical axis is perpendicular to the X optical axis. The optical imaging lens further includes, along the Y optical axis from the object side to the prism: a first lens having a positive refractive power, with a convex object side and a concave image side. The optical imaging lens further includes, in sequence, along the X optical axis from the prism to the image side: a second lens having a negative refractive power, with a concave object side and a convex image side; a third lens having a positive refractive power, with a convex object side and a concave image side; a fourth lens having a refractive power; a fifth lens having a positive refractive power, with a convex object side and a convex image side; and a sixth lens having a negative refractive power, with a concave object side. The number of lenses having a refractive power in the optical imaging lens is six.

[0073] Wherein, the distance PR on the X optical axis from the exit surface of the prism to the object side of the second lens may satisfy: 0.5 mm < PR < 5.0 mm; the effective focal length f2 of the second lens and the effective focal length f3 of the third lens may satisfy: -2.0 < f2 / f3 < -1.2; the effective focal length f5 of the fifth lens and the effective focal length f6 of the sixth lens may satisfy: -1.1 < f5 / f6 < -0.7; the distance G1 on the Y optical axis from the object side of the first lens to the reflection surface of the prism, the distance G2 on the X optical axis from the reflection surface of the prism to the imaging surface of the optical imaging lens, and the total effective focal length f of the optical imaging lens may satisfy: 1.6 < (G1 + G2) / f < 2.0; the effective focal length f1 of the first lens and the total effective focal length f of the optical imaging lens may satisfy: 2.0 < f1 / f < 2.8.

[0074] The present application enables the optical imaging lens to achieve telephoto characteristics by rationally configuring the refractive power and surface shape of each lens. Simultaneously, constraining the ratio of the effective focal length of the second lens to the effective focal length of the third lens, as well as the ratio of the effective focal length of the fifth lens to the effective focal length of the sixth lens, facilitates adjustment of the angle of the paraxial light rays and balances aberrations, thereby ensuring that the optical imaging lens achieves good imaging quality. Furthermore, by providing a prism and rationally configuring the distance from the prism's exit surface to the object side surface of the second lens on the X-axis, the ratio of the overall length of the optical imaging lens on the Y-axis and X-axis to the total effective focal length of the optical imaging lens, and the ratio of the effective focal length of the first lens to the total effective focal length of the optical imaging lens, the tilt sensitivity of the first lens after combining with the prism can be reduced, ensuring that the image resolution is not affected by the anti-shake component during OIS anti-shake compensation. Furthermore, the thickness of the prism can be kept as small as possible, effectively improving ghost images caused by prism internal reflection.
