Description

Technical Field

[0001] This application relates to the field of optical elements, and more specifically, to an optical lens and an electronic device. Background Art

[0002] The lidar lens is a key component for the autonomous driving assistance system to obtain external information. With the rapid development of the autonomous driving assistance system, the demand for lidar lenses is also increasing, and it is developing towards high resolution and miniaturization. At the same time, in order to meet the requirements of safe driving and special installation positions, compared with ordinary optical lenses, the lidar lens in the autonomous driving assistance system has more special requirements. Currently, the market urgently needs an optical lens with high resolution, small FNO, high relative illumination, and miniaturization to meet the applications in automobiles.

[0003] Currently, the existing lidar lenses in the prior art still have many deficiencies: 1) The light transmission ability of the existing lidar lenses is not strong enough to adapt to the darker environments at night or on rainy and cloudy days; 2) The existing lidar lenses cannot meet the requirements of both a small front aperture and miniaturization at the same time; 3) The existing lidar lenses cannot meet the requirements of both small FNO and high resolution at the same time.

[0106] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings.

[0107] It should be noted that in this specification, the expressions such as first, second, and third are only used to distinguish one feature from another feature, and do not represent any limitation on the features. Therefore, without departing from the teachings of the present application, the first lens discussed below may also be referred to as the second lens or the third lens.

[0108] In the drawings, for the sake of convenience of illustration, the thickness, size, and shape of the lens have been slightly exaggerated.

[0109] In this article, the paraxial region refers to the region 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 region; 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 region.

Further, when an expression such as "at least one of..." appears after a list of listed features, it modifies the entire list of listed features rather than an individual element in the list. Further, when describing embodiments of the present application, the use of "may" means "one or more embodiments of the present application". Also, the term "exemplary" is intended to refer to an example or illustration.

[0112] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It should also be understood that terms (such as those defined in a common dictionary) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0113] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0114] The features, principles and other aspects of the present application will be described in detail below.

[0115] In an exemplary embodiment, the optical lens includes, for example, five lenses having optical power, namely, a first lens, a second lens, a third lens, a fourth lens and a fifth lens. These five lenses are arranged in sequence along the optical axis from the first side to the second side, and there may be a spacing distance between any two adjacent lenses among the first lens to the fifth lens.

[0116] In an exemplary embodiment, the optical lens provided by the present application can be used as, for example, a vehicle-mounted lens. At this time, the first side of the optical lens can be the object side, and the second side can be the image side. Light from the object side can be imaged on the image side. The second side surface of the optical lens is the imaging surface of the optical lens.

[0117] In an exemplary embodiment, the optical lens provided by the present application can be used as, for example, a projection lens or a laser radar emission end lens. At this time, the second side of the optical lens can be the image source side, and the first side can be the imaging side. Light from the image source side can be imaged on the imaging side. The second side surface of the optical lens is the image source surface of the optical lens.

[0118] In an exemplary embodiment, the optical lens may further include a photosensitive element disposed on the second side surface. Optionally, the photosensitive element disposed on the second side surface may be a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor device (CMOS).

[0119] In an exemplary embodiment, the optical lens may further include a diaphragm for restricting light beams to further improve the imaging quality of the optical lens. The diaphragm is beneficial for converging the light rays entering the optical system, reducing the maximum clear aperture of the optical system, and reducing the assembly sensitivity of the system. In some embodiments of the present application, the diaphragm may be disposed between the third lens and the fourth lens. More specifically, it may be disposed near the first side surface of the fourth lens. In some embodiments of the present application, the diaphragm may also be disposed between the fourth lens and the fifth lens. More specifically, it may be disposed near the first side surface of the fifth lens. However, it should be noted that the positions of the diaphragms disclosed herein are merely examples and not limitations; in alternative embodiments, the diaphragm may also be disposed at other positions according to actual needs.

[0120] In an exemplary embodiment, the first lens has a positive optical power. Its first side surface is convex and its second side surface is concave. The first lens having a positive optical power and a convex first side surface can collect as much light as possible and enter the rear optical system. The second side surface being concave can make the light enter the rear optical system smoothly as much as possible, which is beneficial for reducing the sensitivity of the system and the front small aperture. The first lens preferably uses a high refractive index material, which is beneficial for reducing the front aperture and improving the imaging quality. In addition, the first side surface of the first lens is designed to be convex, which is beneficial for the water droplets to slide off in practical applications and reduces the influence on imaging.

[0121] In an exemplary embodiment, the second lens has a negative optical power. Its first side surface is concave and its second side surface is concave. The second lens having a negative optical power has the effect of diverging light. Under the same field of view angle, the emitted light rays diverge appropriately and smoothly transition to the rear optical system, realizing a small FNO and high light flux of the system. The first side surface of the second lens is designed to be concave and cooperates with the concave second side surface of the first lens, so that the light rays emitted from the first lens are gently incident on the first side surface of the second lens, which is beneficial for reducing the sensitivity of the light rays from the first lens to the second lens. The second side surface of the second lens is concave and has a relatively large radius of curvature, which can make the light rays rise appropriately, so that the peripheral light rays can reach a higher imaging position, reducing the light energy loss caused by the excessive angle between the light rays reaching the image plane and the chief ray of the chip, and is beneficial for improving the illumination of the edge field of view.

[0122] In an exemplary embodiment, the second lens has a negative focal length, and its first side surface is a concave surface, and its second side surface is a convex surface. The second lens has a negative focal length and has the function of diverging light, and can disperse the central light and the edge light of each field of view. Under the same field of view angle, the light emitted through the second side surface of the second lens can make the rear optical system have a larger light receiving surface, so that the physical aperture of the aperture is expanded, and a larger amount of light is achieved, which is conducive to increasing the illumination of the picture; the first side surface of the second lens is designed to be a concave surface, which cooperates with the concave surface of the second side surface of the first lens, so that the light emitted through the first lens is smoothly incident to the rear, which is conducive to reducing sensitivity; the first side surface of the second lens is a concave setting, and with the high refractive index material, the light presents a divergent trend, weakens the convergence, and allows the peripheral light to reach a higher imaging position, which is conducive to the use with the chip size; the second side surface of the second lens is a convex setting, which can effectively converge and gather the light and reduce the rear port diameter.

[0123] In an exemplary embodiment, the third lens has negative power, and its first side surface is convex and its second side surface is concave. The third lens has negative power and has the function of diverging light. When combined with the negative power of the second lens, it is beneficial for light to enter the rear optical system smoothly. The first side surface of the third lens is designed to be convex, which is beneficial for light to converge properly in the third lens, and the light to transition smoothly, which is beneficial for correcting aberrations and reducing sensitivity. The second side surface of the third lens is concave, which can diverge light, which is beneficial for improving the position of the light aperture, expanding the aperture, and achieving a small FNO.

[0124] In an exemplary embodiment, the third lens has a negative optical power, and its first side surface is a concave surface, and its second side surface is a convex surface. The third lens has a negative focal length, and can collect light entering through the front end, and collect as much light as possible from the second lens, which is conducive to properly diffusing the light, expanding the aperture diameter, and increasing the aperture, so as to achieve a small FNO and high light flux of the system; the first side surface of the third lens is designed to be a concave surface, which can collect as much light as possible in the peripheral field of view and reduce the loss of light energy; the second side surface of the third lens is a convex surface, which can make the light smoothly transition to the rear optical system, and at the same time can appropriately converge and gather the light to reduce the diameter of the rear port.

[0125] In an exemplary embodiment, the fourth lens has positive focal power, and its first side surface is convex and its second side surface is concave. The fourth lens has positive focal power and has the function of converging light, which is beneficial to improving the resolution.

Reasonably controlling the distance between the fourth lens and the fifth lens and the central thickness of the fourth lens, and satisfying (d4 + d45) / TTL≤0.22, is beneficial for achieving high resolution of the system, enabling smooth transition of light, and reducing system sensitivity. More specifically, d4, d45, and TTL may further satisfy 0.07≤(d4 + d45) / TTL≤0.2, which is beneficial for further achieving high resolution of the system, enabling smooth transition of light, and reducing system sensitivity.

[0152] In one embodiment, the optical lens according to the present application may satisfy: 0.5 ≤ R9 / (d4 + d45) ≤ 2.5, where R9 is the radius of curvature of the first side surface of the fifth lens, d4 is the central thickness of the fourth lens on the optical axis, and d45 is the air gap between the fourth lens and the fifth lens on the optical axis.

More specifically, R9, d4, and d45 may further satisfy 0.65 ≤ R9 / (d4 + d45) ≤ 2.2, which is beneficial to further achieving high resolution of the system.

[0153] In one embodiment, the optical lens according to the present application may satisfy: 0.1 ≤ T45 / TTL ≤ 0.45, where T45 is the distance on the optical axis from the first side surface of the fourth lens to the second side surface of the fifth lens, and TTL is the distance on the optical axis from the center of the first side surface of the first lens to the imaging surface of the optical lens. The area between the fourth lens and the fifth lens is a light converging area. Reasonably controlling the distance between the fourth lens and the fifth lens and the overall optical length and satisfying 0.1 ≤ T45 / TTL ≤ 0.45 is beneficial to ensuring a stable light path and achieving miniaturization of the rear end of the system.

More specifically, D7 and D may further satisfy 0.5 ≤ D7 / D ≤ 1.2, which can further achieve miniaturization and high light flux of the system.

[0155] In an exemplary embodiment, as needed, the optical lens of the present application may further include a filter and / or a protective glass disposed between the fifth lens and the imaging surface. The filter can filter light rays with different wavelengths, and the protective glass can prevent elements (such as chips) on the second side of the optical lens from being damaged.

[0156] In an exemplary embodiment, the first lens to the fifth lens may be spherical lenses or aspherical lenses. The present application does not specifically limit the specific number of spherical lenses and aspherical lenses. When focusing on imaging quality, the number of aspherical lenses can be increased, and even all lenses can be aspherical lenses. The characteristic of an aspherical lens is that the curvature continuously changes from the center to the periphery of the lens. Different from a spherical lens with a constant curvature from the center to the periphery of the lens, an aspherical lens has better curvature radius characteristics and has the advantages of improving distortion aberration and astigmatism aberration. After using an aspherical lens, it is possible to eliminate as much aberration as possible during imaging, thereby improving the imaging quality of the lens. The setting of the aspherical lens helps to correct system aberration and improve resolution. Exemplarily, at least one of the first side and the second side of the second lens, the third lens, the fourth lens, and the fifth lens of the present application is an aspherical mirror surface.

[0157] In an exemplary embodiment, the first lens to the fifth lens may be glass lenses or plastic lenses. The present application does not specifically limit the specific number of glass lenses and plastic lenses. An optical lens made of glass can suppress the shift of the back focus of the optical lens with temperature change to improve system stability. At the same time, using glass material can avoid problems such as blurred imaging of the lens and affecting the normal use of the lens caused by high and low temperature changes in the use environment. Specifically, when focusing on temperature performance and resolution quality, the first lens to the fifth lens may all be glass aspherical lenses. In application scenarios with lower requirements for temperature stability, the first lens to the fifth lens in the optical lens may also all be made of plastic. Making optical lenses with plastic can effectively reduce the manufacturing cost. Of course, the first lens to the fifth lens in the optical lens can also be made of a combination of plastic and glass.

[0158] Through reasonable setting of parameters such as the shape and optical power of each lens, the optical lens according to the above embodiment of the present application can have at least one beneficial effect such as miniaturization, high resolution, small aperture, low sensitivity, small FNO, high light throughput, and high performance.

[0159] However, those skilled in the art should understand that without departing from the technical solution claimed in the present application, the number of lenses constituting the lens can be changed to obtain the various results and advantages described in this specification.
