Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of visible light photography, in particular to a fold-hybrid lens, a camera module and a terminal device. BACKGROUND

[0002] Visible light mobile front imaging technology (such as mobile phone front imaging technology) refers to a technology that captures images or videos using visible light waves (about 400-700 nanometers). This technology enables mobile phones to perform high-quality photography and video calls. With the popularity of smartphones and the development of mobile Internet, front cameras have become an indispensable part of smartphones and are widely used in scenarios such as self-portraits, video conferencing, live streaming, and social media interaction. In recent years, as consumers demand higher quality from their phone cameras, front camera technology has continued to evolve, particularly in terms of high-resolution, low-light performance, autofocus, and image stabilization. In addition, with the development of artificial intelligence technology, front cameras have integrated face recognition, expression analysis, and augmented reality (AR) functions, greatly enriching users' experience and application scenarios. In modern smartphones, visible light imaging lenses play a crucial role, and the size of the lens directly affects the compactness, lightweight, and integration of the device.

[0003] A metasurface is an artificial material with a thickness less than the wavelength, composed of a series of two-dimensional structural units at the micron level. The manufacturing process of metasurfaces is relatively simple and can be achieved through conventional photolithography, sputtering, and spraying, etc., with lower cost. By designing metasurfaces, light field information can be efficiently collected to obtain a clear image of an object. Therefore, lenses prepared using metasurface technology significantly reduce the volume and weight of the lens, providing key support for the lightweight design of smartphones. In addition, metasurface technology can achieve complex optical functions (such as chromatic aberration correction and wide-angle imaging), improving imaging quality while reducing the number of lenses and production costs.

[0004] The fold-hybrid system formed by the metasurface lens and the traditional refractive lens can effectively solve the problems in traditional lenses. The fold-hybrid lens usually achieves a high focal length and light path folding, thereby realizing the required optical path length in a relatively small optical system. This helps to reduce the volume and size of the optical system, making it more suitable for compact application scenarios. However, how to combine metasurface lenses with traditional refractive lenses for better optical performance and smaller volume is still a challenge. SUMMARY

[0044] Please see Figure 1 This invention provides a hybrid refractive-hypersurface lens, comprising a plurality of lenses arranged sequentially along the optical axis from the object plane to the image plane; wherein at least one lens is a metasurface lens, and the remaining lenses are non-metasurface lenses;

[0045] Hybrid lenses satisfy:

[0046] Among them, Y d The maximum image height of the hybrid lens is indicated by Fno, the aperture number is indicated by EFL, the focal length is indicated by FOV, the diagonal field of view is indicated by TTL, and the optical length (total optical length) is indicated by the distance from the center of the optical axis on the object side of the first lens closest to the object plane in the hybrid lens to the image plane.

[0047] In this embodiment, by combining metasurface lenses and non-metasurface lenses (i.e., traditional refractive lenses), a hybrid refractive-hypersurface system is constructed, effectively solving many problems associated with traditional refractive lenses. The hybrid refractive-hypersurface lens provided in this embodiment can achieve a higher focal length and a better optical path folding effect, thereby achieving the required optical path length within a relatively small optical system. This characteristic helps to significantly reduce the volume and size of optical systems, making it widely applicable in fields with increasing demands for miniaturization and integration, such as smartphones, wearable devices, and miniature cameras.

[0048] This embodiment, while ensuring focal length and F-number (aperture number), significantly reduces the number of lenses, total TTL optical length, overall size, and manufacturing cost, achieving a large field of view and low F-number optical system. This not only improves optical performance but also enables a lighter design. Furthermore, by utilizing the negative dispersion characteristics of metasurface lenses, achromatic aberration is effectively achieved, thereby realizing high-resolution imaging.

[0049] In one embodiment, the hybrid lens includes a first lens 110, a second lens 120, a third lens 130, a fourth lens 140, and a fifth lens 150 arranged sequentially along the optical axis from the object plane to the image plane;

[0050] Among them, one of the first lens 110, the second lens 120, the third lens 130, the fourth lens 140 and the fifth lens 150 is a metasurface lens, and the remaining lenses are extended aspherical lenses.

[0051] In this embodiment, the metasurface lens consists of a substrate and microstructures disposed on the substrate. These microstructures are composed of a subwavelength-scale micro / nano unit array. Each micro / nano unit structure has a specific shape, size, and arrangement to achieve precise control over the phase, amplitude, or polarization state of the incident light wave. Specifically, the period of the micro / nano unit structure is 250-400 nm, preferably 350 nm; the height is 600-1000 nm, preferably 600 nm; the diameter of the micro / nano unit structure covers 100-250 nm; the material is preferably silicon dioxide; and they are arranged in square, hexagonal, or other shapes. Through the design of the micro / nano unit structure, the metasurface lens can achieve optical performance comparable to or even better than traditional lenses while maintaining a thin and light volume, such as high transmittance, low chromatic aberration, and low distortion.

[0052] In this embodiment, the extended aspherical lens is made of traditional optical materials, such as glass or plastic, and its surface is precisely machined to form an aspherical shape to achieve focusing or diverging of light. The extended aspherical lens, combined with the metasurface lens, works synergistically to further enhance the optical performance of the hybrid folding-hybrid lens. For example, the extended aspherical lens can compensate for minor errors that may exist in the metasurface lens to a certain extent, making the overall optical performance of the hybrid folding-hybrid lens more stable and superior. Furthermore, the material of each extended aspherical lens is preferably plastic, which has high plasticity and processing flexibility, can meet the design requirements of various complex shapes, and plastic is lighter than glass, helping to reduce the overall weight of the hybrid folding-hybrid lens.

[0053] In this embodiment, under the arrangement of the five lenses as described above, the distance TTL from the optical axis center of the object side of the first lens 110 to the image plane satisfies: Hybrid lenses within this range maintain a compact size while delivering excellent image quality. The TTL value settings ensure that the hybrid lens provides sufficient back focal length within a compact structure to meet the mounting requirements of imaging components such as image sensors. Furthermore, the TTL range also considers the adaptability of hybrid lenses in various application scenarios, ensuring they produce clear images under different lighting conditions and shooting distances.

[0054] In some preferred embodiments, the second lens 120 is a metasurface lens; the first lens 110, the third lens 130, the fourth lens 140 and the fifth lens 150 are all extended aspherical lenses;

[0055] The first lens 110 has positive optical power, the object side of the first lens 110 is convex and has a positive radius of curvature, and the image side of the first lens 110 is concave and has a positive radius of curvature.

[0056] The second lens 120 has positive optical power, the object side of the second lens 120 is a plane, and the image side of the second lens 120 is a binary plane; microstructures are arranged on the image side of the second lens 120.

[0057] The third lens 130 has positive optical power, the object side of the third lens 130 is concave and has a positive radius of curvature, and the image side of the third lens 130 is convex and has a positive radius of curvature.

[0058] The fourth lens 140 has positive optical power, the object side of the fourth lens 140 is concave and has a negative radius of curvature, and the image side of the fourth lens 140 is convex and has a negative radius of curvature.

[0059] The fifth lens 150 has negative optical power, the object side of the fifth lens 140 is concave and has a negative radius of curvature; the image side of the fifth lens 150 is a convex surface with a central concave region, the central region of the image side of the fifth lens 150 has a negative radius of curvature, and the edge region of the image side of the fifth lens 150 has a positive radius of curvature.

[0060] In this preferred embodiment, by combining different lenses and designing the surface shape and optical power of each lens, good imaging effect and optical performance can be achieved. Specifically, the planar shape and different curvature distribution of the object-side and image-side surfaces can achieve a reasonable distribution of the lens's optical power and effectively balance aberrations such as spherical aberration, coma, and distortion. More specifically, the positive optical power and specific surface shape of the first lens 110 help to converge light, improving the clarity and contrast of the image. The second lens 120, as a metasurface lens, can achieve more precise control of light through its planar object-side surface, binary image-side surface, and the microstructures arranged on the image-side surface, further improving chromatic aberration and imaging quality. The third lens 130 and the fourth lens 140 both adopt positive optical power and a concave object-side surface and a convex image-side surface design, which helps to further correct aberrations and improve the accuracy and stability of imaging. The negative optical power and special image-side surface shape of the fifth lens 150, namely the design of a central concave region and a positive radius of curvature at the edges, help to balance the optical power distribution of the entire system, achieving a wider field of view and less distortion. In summary, this preferred embodiment demonstrates excellent performance in terms of image quality, optical properties, and applicability. Furthermore, the material of the second lens 120 can be silicon dioxide or silicon nitride, etc.; the thickness of the second lens 120 ranges from 0.2 to 0.3 mm.

[0061] In one embodiment, the superconducting lens further includes an aperture stop 170, which is located on the object side of the first lens 110, or in the optical path between the first lens 110 and the second lens 120, or in the optical path between the second lens 120 and the third lens 130.

[0062] In this embodiment, the design of the aperture 170 helps control the path of light through the lens, reducing stray light interference and thus improving image quality. The position of the aperture 170 can be adjusted according to actual needs to achieve the best imaging effect. For example, when the aperture 170 is located on the object side of the first lens 110, it can effectively limit the angle of light entering the lens and reduce interference from edge light. When the aperture 170 is located in the optical path between lenses, it can more finely control the light distribution between different lenses, further optimizing imaging performance.

[0063] It is clear that the primary function of the 170 aperture is to intercept and restrict the path of light entering the lens. Setting the 170 aperture in different positions will result in variations in the aperture diameter of the light beam. By appropriately adjusting the size of the 170 aperture, the same 170 aperture effect can be achieved in different positions.

[0064] Based on the above scheme, the focal length f of the folding-hybrid lens satisfies: f≥2.1mm. Within this focal length range, the folding-hybrid lens can ensure clear images at various shooting distances and has sufficient magnification to meet users' needs for detail capture.

[0065] Based on the above scheme, the diagonal field of view (FOV) of the folding-hybrid lens can meet the following requirement: FOV ≥ 90°. Within this diagonal FOV range, the folding-hybrid lens can capture a wider scene and bring users a more stunning visual experience.

[0066] Based on the above scheme, the operating temperature range of the folding-hybrid lens can be -30℃ to 70℃. Within this operating temperature range, the folding-hybrid lens can maintain stable performance and imaging quality, and adapt to various extreme environmental conditions.

[0067] The following will provide a more detailed description of the lens optical parameter data based on the preferred embodiments described in the examples above. Specifically, as shown... Figure 1 As shown, the hybrid lens includes an aperture stop 170, a first lens 110, a second lens 120, a third lens 130, a fourth lens 140, a fifth lens 150, and an imaging plane 160 arranged sequentially along the optical axis from the object plane to the image plane. The second lens 120 is a metasurface lens, and the other lenses are extended aspherical lenses made of plastic. The incident light enters through the object side of the aperture stop 170, passes through the first lens 110, and then passes through the second lens 120, the third lens 130, the fourth lens 140, and the fifth lens 150 in sequence before finally converging on the imaging plane 160.

[0068] The optical parameters of this hybrid lens can be found in the example in Table 1.

For example, surface number 1 represents aperture 170, surface numbers 2 and 3 represent the object side and image side of the first lens 110, and so on, with the final surface number 12 representing the imaging surface 160. The radius of curvature represents the curvature of the lens surface. A positive value indicates that the surface bends towards the image surface, and a negative value indicates that the surface bends towards the object surface. "Standard" represents the standard surface, "Extended sphere" represents the extended aspherical surface, "Binary2" represents the binary surface, and "Infinity" indicates that the surface is flat. The spacing represents the central axial distance from the current surface to the next surface. The units for both the radius of curvature and the spacing are millimeters (mm). The aperture represents the effective light transmission diameter of the lens at each position.

[0072] The surface shape of each extended aspherical lens satisfies the following equation:

[0075] The conic coefficient k and higher-order coefficient Ai of each extended aspherical lens are shown in Table 2 below.

[0079] In Table 2, -25.947 represents the specific value of the conic coefficient k for face number 2, 5.350315 represents the specific value of the coefficient A3 for face number 2, and so on.

[0080] The metasurface phase of the second lens 120 (i.e., the metasurface lens) can be referenced from the example in Table 3.

[0083] In Table 3, R1 represents the normalized radius of the binary surface of the metasurface lens, and B2 to B9 represent the coefficients of the metasurface phase.

[0084] In the preferred embodiment of this example, the focal length f satisfies the following relationship with the diagonal field of view (FOV) and the maximum image height. The optical total length TTL and the aperture Fno satisfy the following conditions:

[0085] The preferred embodiment of this example provides a hybrid lens with a working wavelength of 435-650nm, an F-number of 2.22, a focal length of 2.15mm, and a maximum field of view of 90°, which meets the requirements for lens use.

[0086] Figure 2 The diagram shows the modulation curve of the superconducting hybrid lens provided in this embodiment of the invention at a frequency of 100 line pairs per millimeter. The curve is smooth, the value is high, and the evaluation value of the edge field of view reaches 45%, which can provide high-quality imaging.

[0087] Figure 3 This is a schematic diagram of the diffusion pattern of the fold-hybrid lens provided in an embodiment of the present invention. The diffusion pattern of the fold-hybrid lens provided in this embodiment of the present invention is relatively concentrated and uniformly distributed across the entire spectral band, which can meet the requirements of high-resolution imaging.

Figure 4 As shown, the superconducting lens provided in this embodiment of the invention has a relative illuminance of more than 50% within a 0.7 field of view in the working band, and uniform brightness.

[0089] In summary, the hybrid lens provided by the embodiments of the present invention has a relatively large aperture, clear imaging, small total optical length (TTL), and lighter integration. Based on the synergistic cooperation of metasurface lenses and various extended aspherical lenses, it achieves effective control of light after passing through materials with different refractive indices, and achieves good achromatic aberration to meet the requirements of high-resolution imaging.
