Description

Technical Field

[0001] This invention relates to the field of imaging equipment technology, and more specifically, to a humanoid eyeglass lens. Background Technology

[0002] Humanoid glasses lenses are core components for performance testing of AR and VR modules. They employ a large number of lenses, especially for humanoid glasses lenses with seventeen lenses. The large lens size makes it difficult to reduce the lens size, significantly impacting the optical path and compromising image quality and testing accuracy for AR and VR modules. Therefore, miniaturizing the lens is challenging, making it difficult to integrate into smaller products. Thus, controlling the overall length and optical parameters of humanoid glasses lenses to reduce lens size while maintaining high image quality is a crucial issue. Summary of the Invention

[0003] The main objective of this invention is to provide a humanoid eyeglass lens to solve the problem of simultaneously achieving miniaturization and high image quality in existing humanoid eyeglass lenses.

[0004] To achieve the above objectives, according to one aspect of the present invention, a humanoid eyeglass lens is provided, comprising, from the object side to the image side, the following sequentially: a first lens group, comprising a first lens to an eleventh lens, the combined focal length of the first lens group being negative; and a second lens group, comprising a twelfth lens to a seventeenth lens, the combined focal length of the second lens group being positive; wherein the first lens to the seventeenth lens are all spherical lenses; and the distance TTL between the object side surface of the first lens and the imaging plane of the humanoid eyeglass lens on the optical axis of the humanoid eyeglass lens, and the effective focal length f of the humanoid eyeglass lens, satisfy the following condition: 24.0. <TTL / f<34.9。

[0005] According to another aspect of the present invention, there is provided a humanoid eye lens, sequentially comprising from the object side to the image side of the humanoid eye lens: a first lens group, the first lens group sequentially comprising a first lens to an eleventh lens from the object side to the image side of the humanoid eye lens, wherein the combined focal length of the first lens group is negative; a second lens group, the second lens group sequentially comprising a twelfth lens to a seventeenth lens from the object side to the image side of the humanoid eye lens, wherein the combined focal length of the second lens group is positive; wherein the combined focal length fg1 of the first lens group and the effective focal length f of the humanoid eye lens satisfy: -5.5 < fg1 / f < -1.5, and the combined focal length fg2 of the second lens group and the effective focal length f of the humanoid eye lens satisfy: 7.8 < fg2 / f < 9.3. The present application provides a humanoid eye lens with seventeen lenses, which adopts a secondary imaging optical architecture. Since the humanoid eye lens has a large field of view, the secondary imaging optical architecture reasonably distributes the combined focal lengths of the first lens group and the second lens group. The first lens group transmits large-field-of-view light to an intermediate image plane, and the second lens group performs secondary imaging on the primary image plane, which is beneficial for reasonably controlling the propagation trend of light, controlling the total length of the humanoid eye lens, realizing miniaturization and light weight of the lens, and is also beneficial for balancing aberrations such as field curvature, astigmatism and spherical aberration of the humanoid eye lens, and improving the imaging quality of the humanoid eye lens.

[0006] Further, the combined focal length fg1 of the first lens group and the effective focal length f of the humanoid eye lens satisfy: -5.5 < fg1 / f < -1.5, and the combined focal length fg2 of the second lens group and the effective focal length f of the humanoid eye lens satisfy: 7.8 < fg2 / f < 9.3.

[0007] Further, the effective focal length f1 of the first lens and the effective focal length f2 of the second lens satisfy: -0.8 < f1 / f2 < 0.3.

[0008] Further, the effective focal length f3 of the third lens and the effective focal length f4 of the fourth lens satisfy: 2.5 < (f4+f3) / (f4-f3) < 6.9.

[0009] Further, the effective focal length f5 of the fifth lens and the combined focal length fg1 of the first lens group satisfy: -5 < f5 / fg1 < 120.0.

[0010] Further, the effective focal length f6 of the sixth lens, the effective focal length f7 of the seventh lens, and the effective focal length f8 of the eighth lens satisfy: -19.0 < (f6+f7) / f8 < -7.8.

[0011] Further, the effective focal length f6 of the sixth lens, the effective focal length f7 of the seventh lens, the effective focal length f8 of the eighth lens, and the combined focal length fg1 of the first lens group satisfy: -6.3 < (f6+f7+f8) / fg1 < -3.5.

[0012] Furthermore, the effective focal length f10 of the tenth lens, the effective focal length f11 of the eleventh lens, and the effective focal length f9 of the ninth lens satisfy the following condition: 2.5 < |(f10+f11) / f9| < 7.0.

[0013] Furthermore, the distance T1213 between the image side of the twelfth lens and the object side of the thirteenth lens on the optical axis satisfies: T1213 < 0.5 mm.

[0014] Furthermore, the center thickness CT12 of the twelfth lens and the center thickness CT13 of the thirteenth lens satisfy the following relationship: 1.7 <CT12 / CT13<2.1。

[0015] Furthermore, the Abbe number of the thirteenth lens is less than that of the twelfth, fourteenth, fifteenth, and sixteenth lenses, and the Abbe number of the seventeenth lens is less than that of the twelfth, fourteenth, fifteenth, and sixteenth lenses.

[0016] Furthermore, the refractive index of the thirteenth lens is greater than that of the twelfth, fourteenth, fifteenth, and sixteenth lenses, and the refractive index of the seventeenth lens is greater than that of the twelfth, fourteenth, fifteenth, and sixteenth lenses.

[0017] Applying the technical solution of this invention, from the object side to the image side of the anthropomorphic lens, the anthropomorphic lens sequentially includes a first lens group and a second lens group. The first lens group, from the object side to the image side of the anthropomorphic lens, sequentially includes a first lens to an eleventh lens, and the combined focal length of the first lens group is negative. The second lens group, from the object side to the image side of the anthropomorphic lens, sequentially includes a twelfth lens to a seventeenth lens, and the combined focal length of the second lens group is positive. Among these, the first to seventeenth lenses are all spherical lenses. The distance TTL between the object side of the first lens and the imaging plane of the anthropomorphic lens on the optical axis of the anthropomorphic lens, and the effective focal length f of the anthropomorphic lens, satisfy the following condition: 24.0. <TTL / f<34.9。

[0018] This application provides a humanoid eyeglass lens with seventeen lenses, employing a secondary imaging optical architecture. By limiting the positive and negative values ​​of the combined focal length of the first and second lens groups, and ensuring that the TTL / f (telephoto ratio of the humanoid eyeglass lens) is within a reasonable range, the first lens group transmits light from a large field of view to the intermediate image plane, while the second lens group performs secondary imaging on the primary image plane. This facilitates reasonable control of light trajectory, ensuring image quality while controlling the overall length of the humanoid eyeglass lens, achieving lens miniaturization and weight reduction. Furthermore, it allows for a longer effective focal length with a shorter overall lens length, expanding the lens's applicable scenarios and enhancing product competitiveness.

Detailed Implementation

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] 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 one of ordinary skill in the art to which this application pertains.

[0035] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0036] In the accompanying drawings, the thickness, size, and shape of the lenses have been slightly exaggerated for ease of illustration. Specifically, the shapes of the spherical or aspherical surfaces shown in the drawings are illustrated by way of example. That is, the shapes of the spherical or aspherical surfaces are not limited to those shown in the drawings. The drawings are for illustrative purposes only and are not drawn strictly to scale.

[0037] In this paper, the paraxial region refers to the region near the optical axis. If the lens surface is convex and the location of that convexity is not defined, it means that the lens surface is convex at least in the paraxial region; if the lens surface is concave and the location of that concaveness is not defined, it means that the lens surface is concave at least in the paraxial region. The determination of the surface shape in the paraxial region can be based on the judgment method commonly used by those knowledgeable in the field, using the R value (R refers to the radius of curvature of the paraxial region, usually the R value in the lens data in optical software) to determine convexity or concavity. For the object side, a positive R value indicates a convex surface, and a negative R value indicates a concave surface; for the image side, a positive R value indicates a concave surface, and a negative R value indicates a convex surface.

[0038] To address the challenge of balancing miniaturization and high image quality in existing humanoid eyeglass lenses, this invention provides a humanoid eyeglass lens.

[0039] First Implementation Method

[0040] like Figures 1 to 26 As shown, from the object side to the image side of the anthropomorphic lens, the anthropomorphic lens sequentially includes a first lens group and a second lens group. The first lens group, from the object side to the image side, includes lenses one through eleven, and the combined focal length of the first lens group is negative. The second lens group, from the object side to the image side, includes lenses twelfth through seventeenth, and the combined focal length of the second lens group is positive. Lenses one through seventeen are all spherical lenses. The distance TTL between the object side of the first lens and the imaging plane of the anthropomorphic lens on the optical axis of the anthropomorphic lens, and the effective focal length f of the anthropomorphic lens, satisfy the following condition: 24.0. <TTL / f<34.9。

[0041] This application provides a humanoid eyeglass lens with seventeen lenses, employing a secondary imaging optical architecture. By limiting the positive and negative values ​​of the combined focal length of the first and second lens groups, and ensuring that the TTL / f (telephoto ratio of the humanoid eyeglass lens) is within a reasonable range, the first lens group transmits light from a large field of view to the intermediate image plane, while the second lens group performs secondary imaging on the primary image plane. This facilitates reasonable control of light trajectory, controlling the overall length of the humanoid eyeglass lens while ensuring image quality. This achieves lens miniaturization and weight reduction, and allows for a longer effective focal length with a shorter overall lens length, expanding the lens's applicable scenarios and enhancing product competitiveness.

[0042] Preferably, 24.0<TTL / f<34.9.

[0043] In this embodiment, between the combined focal length fg1 of the first lens group and the effective focal length f of the humanoid eye lens, the following relationship is satisfied: -5.5<fg1 / f<-1.5; between the combined focal length fg2 of the second lens group and the effective focal length f of the humanoid eye lens, the following relationship is satisfied: 7.8<fg2 / f<9.3. By limiting fg1 / f and fg2 / f within a reasonable range, since the humanoid eye lens has a large field of view, the secondary imaging optical architecture is adopted to reasonably distribute the combined focal lengths of the first lens group and the second lens group. The first lens group transmits large-field-of-view light to an intermediate image plane, and the second lens group performs secondary imaging on the primary image plane, which is beneficial to balancing aberrations such as field curvature, astigmatism and spherical aberration of the humanoid eye lens, and improves the imaging quality of the humanoid eye lens. Preferably, -5.5<fg1 / f<-1.5 and 7.8<fg2 / f<9.3.

[0044] In this embodiment, between the effective focal length f1 of the first lens and the effective focal length f2 of the second lens, the following relationship is satisfied: -0.8<f1 / f2<0.3. By limiting f1 / f2 within a reasonable range, it is beneficial to reasonably distribute the optical power of the first lens and the second lens, reduce the deflection angle of incident light, and reduce the lens sensitivity. At the same time, an excessively large surface inclination angle is avoided, thereby ensuring good manufacturability and processability of the first lens and the second lens. Preferably, -0.8<f1 / f2<0.3.

[0045] In this embodiment, between the effective focal length f3 of the third lens and the effective focal length f4 of the fourth lens, the following relationship is satisfied: 2.5<(f4+f3) / (f4-f3)<6.9. By limiting (f4+f3) / (f4-f3) within a reasonable range, the third lens is a positive lens and the fourth lens is a positive lens. Reasonably distributing the optical power of the third lens and the fourth lens can further smooth the light, reduce the light deflection angle, and balance various aberrations such as spherical aberration, coma and astigmatism. Preferably, 2.5<(f4+f3) / (f4-f3)<6.9.

[0046] In this embodiment, between the effective focal length f5 of the fifth lens and the combined focal length fg1 of the first lens group, the following relationship is satisfied: -5<f5 / fg1<120.0. By limiting f5 / fg1 within a reasonable range, the fifth lens is a positive lens, and its optical power is appropriately reduced compared with that of the first four lenses. Reasonably distributing the proportion of optical power of the fifth lens is beneficial to balancing the distortion and field curvature of the humanoid eye lens. Preferably, -5<f5 / fg1<120.0.

[0047] In this embodiment, the effective focal lengths f6 of the sixth lens, f7 of the seventh lens, and f8 of the eighth lens satisfy the condition: -19.0 < (f6 + f7) / f8 < -7.8. By limiting (f6 + f7) / f8 within a reasonable range, the spherical aberration contribution of these six to eight lenses can be reasonably controlled within a reasonable level, resulting in good imaging quality in the on-axis field of view. Preferably, -19.0 < (f6 + f7) / f8 < -7.8.

[0048] In this embodiment, the effective focal length f6 of the sixth lens, the effective focal length f7 of the seventh lens, the effective focal length f8 of the eighth lens, and the combined focal length fg1 of the first lens group satisfy the following condition: -6.3 < (f6 + f7 + f8) / fg1 < -3.5. By limiting (f6 + f7 + f8) / fg1 within a reasonable range, the proportion of the optical power of the sixth, seventh, and eighth lenses in the first lens group is rationally configured, avoiding excessive concentration of optical power. This effectively reduces lens sensitivity, simplifies assembly and adjustment, and balances spherical aberration, chromatic aberration, and astigmatism of the entire anthropomorphic lens. Preferably, -6.3 < (f6 + f7 + f8) / fg1 < -3.5.

[0049] In this embodiment, the effective focal length f10 of the tenth lens, the effective focal length f11 of the eleventh lens, and the effective focal length f9 of the ninth lens satisfy the condition: 2.5 < |(f10+f11) / f9| < 7.0. By limiting |(f10+f11) / f9| to a reasonable range, the optical power of the tenth and eleventh lenses is rationally allocated, the angle of light rays exiting from the ninth lens is reduced, and the light rays enter the twelfth lens more smoothly, ensuring that the ninth, tenth, and eleventh lenses have good manufacturability, while also correcting aberrations. Preferably, 2.5 < |(f10+f11) / f9| < 7.0.

[0050] In this embodiment, the distance T1213 between the image-side surface of the twelfth lens and the object-side surface of the thirteenth lens on the optical axis satisfies: T1213 < 0.5 mm. By limiting T1213 to a reasonable range, it is beneficial to balance the spherical aberration, chromatic aberration, and astigmatism of the anthropomorphic lens, thereby improving image quality. Furthermore, it provides a certain margin for structural design and assembly, reducing the difficulty of structural design and increasing the success rate of assembly. Preferably, T1213 < 0.5 mm.

[0051] In this embodiment, the center thickness CT12 of the twelfth lens and the center thickness CT13 of the thirteenth lens satisfy: 1.7<CT12 / CT13<2.1. By limiting CT12 / CT13 within a reasonable range and reasonably controlling the center thicknesses of the twelfth lens and the thirteenth lens on the optical axis, the total length of the human eye-like lens can be effectively reduced to ensure the lightness and thinness of the lens, and the processing sensitivity of the human eye-like lens can also be reduced. Preferably, 1.7<CT12 / CT13<2.1.

[0052] In this embodiment, the Abbe number of the thirteenth lens is smaller than the Abbe numbers of the twelfth lens, the fourteenth lens, the fifteenth lens and the sixteenth lens, and the Abbe number of the seventeenth lens is smaller than the Abbe numbers of the twelfth lens, the fourteenth lens, the fifteenth lens and the sixteenth lens. By reasonably configuring the materials of the second lens group, chromatic aberration can be better corrected on one hand, avoiding problems such as purple fringing during shooting, and costs can be better saved on the other hand.

[0053] In this embodiment, the refractive index of the thirteenth lens is higher than the refractive indices of the twelfth lens, the fourteenth lens, the fifteenth lens and the sixteenth lens, and the refractive index of the seventeenth lens is higher than the refractive indices of the twelfth lens, the fourteenth lens, the fifteenth lens and the sixteenth lens. By reasonably distributing the refractive indices of the lenses in the second lens group, it is beneficial to the balance of various aberrations such as spherical aberration, astigmatism, field curvature and coma of the entire human eye-like lens, improves imaging quality, can also reasonably control the traveling direction of the entire light ray, reduces system sensitivity, and is conducive to the miniaturization of the lens.

[0054] Second Embodiment

[0055] As Figures 1 to 26 shown, from the object side to the image side of the human eye-like lens, the human eye-like lens sequentially comprises a first lens group and a second lens group, the first lens group sequentially comprises a first lens to an eleventh lens from the object side to the image side of the human eye-like lens, and the combined focal length of the first lens group is negative; the second lens group sequentially comprises a twelfth lens to a seventeenth lens from the object side to the image side of the human eye-like lens, and the combined focal length of the second lens group is positive; wherein, the combined focal length fg1 of the first lens group and the effective focal length f of the human eye-like lens satisfy: -5.5<fg1 / f<-1.5, and the combined focal length fg2 of the second lens group and the effective focal length f of the human eye-like lens satisfy: 7.8<fg2 / f<9.3.

[0056] This application provides a humanoid eyeglass lens with seventeen lenses, employing a secondary imaging optical architecture. Due to the large field of view of the humanoid eyeglass lens, the secondary imaging optical architecture rationally allocates the combined focal length of the first lens group and the second lens group. The first lens group transmits the large field of view light to the intermediate image plane, and the second lens group performs secondary imaging on the primary image plane. This is beneficial for rationally controlling the light path, controlling the overall length of the humanoid eyeglass lens, achieving lens miniaturization and weight reduction, and also helps to balance aberrations such as field curvature, astigmatism, and spherical aberration of the humanoid eyeglass lens, thereby improving the imaging quality of the humanoid eyeglass lens.

[0057] Preferably, -5.5 <fg1 / f<-1.5。

[0058] Preferably, 7.8 <fg2 / f<9.3。

[0059] This implementation may also include other conditional expressions from the first implementation, which will not be elaborated here.

[0060] Optionally, the aforementioned anthropomorphic eyepiece may further include a filter for correcting color deviation and / or a protective glass for protecting the photosensitive element located on the imaging plane. The anthropomorphic eyepiece in this application may employ multiple lenses, such as the six lenses described above. By rationally allocating the effective focal length, surface shape, center thickness of each lens, and on-axis distance between each lens, the aperture of the anthropomorphic eyepiece can be effectively increased, the lens sensitivity reduced, and the lens's manufacturability improved, making the anthropomorphic eyepiece more suitable for manufacturing and processing and applicable to portable electronic devices such as smartphones.

[0061] However, those skilled in the art will understand that the number of lenses constituting the anthropomorphic eyepiece 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 anthropomorphic eyepiece is not limited to including six lenses. If necessary, the anthropomorphic eyepiece may also include other numbers of lenses.
