It should be noted that, in the absence of a conflict, embodiments of the disclosure can be combined with features in the embodiments. The disclosure will be described in detail below with reference to the drawings and in conjunction with embodiments.


The features, principles and other aspects of the disclosure are described in detail below.


According to exemplary embodiments of the disclosure, an optical imaging lens assembly may include, for example, seven lenses with focal powers, i.e., a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens. The seven lenses fall into place from an object side to an image side along an optical axis. There may be air space between adjacent lenses.


In an exemplary embodiment, the first lens can have a positive focal power, wherein an object-side surface thereof is a convex surface, and an image-side surface thereof is a concave surface; the second lens can have a positive focal power or a negative focal power; the third lens can have a positive focal power or a negative focal power; the fourth lens can have a positive focal power or a negative focal power; the fifth lens can have a positive focal power or a negative focal power; the sixth lens can have a positive focal power; and the seventh lens can have a negative focal power, wherein an object-side surface thereof is a concave surface, and an image-side surface thereof is a concave surface. The aberration of the optical system can be effectively balanced and the imaging quality can be improved by reasonably combining focal power and surface type of lenses in the optical system.


In an exemplary embodiment, an image-side surface of the fifth lens is a concave surface. In an exemplary embodiment, an object-side surface of the sixth lens is a convex surface.


In an exemplary embodiment, DT11 is a maximum effective radius of the object-side surface of the first lens, DT12 is a maximum effective radius of the image-side surface of the first lens, and ImgH is a half of a diagonal length of an effective pixel region on an imaging surface of the optical imaging lens assembly, DT11, DT12 and ImgH meet: 2.4<(DT11+DT12)/ImgHx5<2.7. Maximum effective radius of the object-side surface of the first lens, maximum effective radius of the image-side surface of the first lens, and the ratio of the sum of maximum effective radius of the object-side surface of the first lens and maximum effective radius of the image-side surface of the first lens to ImgH is a half of a diagonal length of an effective pixel region on an imaging surface of the optical imaging lens assembly are reasonably set, which is not only beneficial to reasonably control the uniform shape transition of the first lens and the reliability of subsequent lens forming and assembly, but also beneficial to reasonably limit the incident range of light. In this way, the refraction angle of light in the first lens is relatively small, thus reducing the off-axis aberration and reducing the system sensitivity.


In an exemplary embodiment, ImgH is a half of a diagonal length of an effective pixel region on an imaging surface of the optical imaging lens assembly, ImgH meets: ImgH>6.2 mm. Setting ImgH according to the above conditions is beneficial to realize large imaging surface and high aperture of the lens and allows the optical imaging lens assembly group to have higher resolution.


In an exemplary embodiment, a refractive index N1 of the first lens and a refractive index N2 of the second lens meet:N1+N2>3.3. Reasonable setting of the refractive index of the first lens and the second lens is beneficial to improve the performance of the optical system.


In an exemplary embodiment, TTL is a distance from the object-side surface of the first lens to the imaging surface of the optical imaging lens assembly on the optical axis, TTL and ImgH meet:TTL/ImgH<1.25. Reasonable setting of the ratio of the distance from the object-side surface of the first lens to the imaging surface of the optical imaging lens assembly on the optical axis to the half of the diagonal length of the effective pixel region on the imaging surface of the optical imaging lens assembly is beneficial to achieve ultra-thin and compact optical imaging lens assembly.


In an exemplary embodiment, an Abbe number V1 of the first lens and an Abbe number V2 of the second lens meet: 78<V1+V2<88. Reasonable setting of the value range of the sum of the Abbe number of the first lens and the second lens is beneficial to reasonably control the dispersion of the optical system and improve the ability of correcting chromatic aberration of the optical system, thus allowing the optical system to have better imaging results.


In an exemplary embodiment, a total effective focal length f of the optical imaging lens assembly, an effective focal length f1 of the first lens, an effective focal length f6 of the sixth lens, and an effective focal length f7 of the seventh lens meet: 0.54/(f1+f607)<1.0. Reasonable setting of the ratio of the total effective focal length of the optical imaging lens assembly to the sum of the effective focal length of the first lens, the sixth lens and the seventh lens is beneficial to control the contribution of the lens to the aberration of the whole optical system and effectively balance the off-axis aberration of the system, thus improving the imaging quality of the optical system.


In an exemplary embodiment, a curvature radius R1 of the object-side surface of the first lens, a curvature radius R2 of the image-side surface of the first lens, a curvature radius R3 of an object-side surface of the second lens, and a curvature radius R4 of an image-side surface of the second lens meet: 0.3<(R1+R2)/(R3+R4)<0.8. Reasonable setting of the ratio of the sum of the curvature radius of the object-side surface and the image-side surface of the first lens to the sum of the curvature radius of the object-side surface and the image-side surface of the second lens is beneficial to realize the deflection of the optical path and balance the senior spherical aberration produced by the optical system.


In an exemplary embodiment, the effective focal length f7 of the seventh lens, a curvature radius R13 of the object-side surface of the seventh lens, and a curvature radius R14 of the image-side surface of the seventh lens meet: 0.2<f7/(R13−R14)<0.6, for example, 0.3<f7/(R13−R14)<0.5. Reasonable setting of the ratio of the effective focal length f7 of the seventh lens to the difference between the curvature radius of the object-side surface and the image-side surface of the seventh lens is beneficial to reasonably control the deflection angle of the marginal ray of the optical system, ensure the good machinability of the optical lens and reduce the sensitivity of the system.


In an exemplary embodiment, FOV is a maximum field of view of the optical imaging lens assembly, FOV meets: 82°<FOV<88°. Reasonable setting of the largest field-of-view angle is beneficial to control the imaging range of the optical system.


In an exemplary embodiment, a distance T45 between the fourth lens and the fifth lens on the optical axis, a distance T56 between the fifth lens and the sixth lens on the optical axis, a distance T67 between the sixth lens and the seventh lens on the optical axis, a center thickness CT5 of the fifth lens on the optical axis, a center thickness CT6 of the sixth lens on the optical axis, and a center thickness CT7 of the seventh lens on the optical axis meet 0.8<(T45+T56+T67)/(CT5+CT6+CT7)<1.2. Reasonable setting of the relationship between the distance between the lenses and the center thickness according to the relationship conditions above is beneficial to control the field curvature contribution of each field of view in the optical system within a reasonable range, thus balancing the field curvature generated by other lenses and effectively improving the resolution of the lens.


In an exemplary embodiment, at least one of the first lens to the seventh lens is made of glass. The use of glass lenses in the optical imaging lens assembly can have at least one of the following advantages: a wider refractive index distribution of glass, a wider selection of materials, and a lower thermal expansion coefficient of glass. Meanwhile, because of the low thermal expansion coefficient of glass, the application of glass lenses in the optical imaging system can mitigate the adverse effects caused by ambient temperature and improve the thermal stability of the optical system.


In an exemplary embodiment, the optical imaging lens assembly further includes a diaphragm. The diaphragm can be arranged at an appropriate position as required. For example, it may be arranged between the object side and the first lens. Optionally, the optical imaging lens assembly may further include an optical filter for correcting color deviation and/or protective glass for protecting a photosensitive element located on the imaging surface.


The optical imaging lens assembly according to the above embodiments of the disclosure may include a plurality of lenses such as the seven lenes above. The optical imaging lens assembly of the disclosure meets the requirements of high aperture, large imaging surface, high pixel, portability and the like, and adopts a lens structure combining glass lenses and plastic lenses to effectively improve the performance of the optical system.


In an exemplary embodiment, at least one surface of each lens is an aspheric surface, that is, at least one surface from the object-side surface of the first lens to the image-side surface of the seventh lens is an aspheric surface. The characteristic of an aspheric lens is that the curvature changes continuously from the center to the periphery of the lens. Different from the spherical lens with constant curvature from the center to the periphery of the lens, the aspheric lens has better curvature radius characteristics and advantages of improving distortion aberration and astigmatic aberration. Using the aspheric lens can eliminate the aberration during imaging as much as possible, thus improving the imaging quality. Optionally, at least one of the object-side surface and the image-side surface of each of the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens and the seventh lens is an aspheric surface. Optionally, the object-side surface and the image-side surface of each of the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens and the seventh lens are aspheric surfaces.


The disclosure also provides an imaging device. Its electronic photosensitive element may be a charge coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS). The imaging device may be an independent imaging device such as a digital camera or an imaging module integrated on a mobile electronic device such as a mobile phone. The imaging device is equipped with an optical imaging lens assembly described above.


Exemplary embodiments of the disclosure also provide an electronic device including an imaging device described above.


However, it should be understood by those skilled in the art that the number of lenses constituting an optical imaging lens assembly can be changed to achieve the various results and advantages described in the Specifications, without departing from the technical scheme claimed herein. For example, although seven lenses are described in the embodiments, the optical imaging lens assembly is not limited to including seven lenses. If necessary, the optical imaging lens assembly group may further include other numbers of lenses.


Preferred embodiments of the optical imaging lens assembly applicable to the above embodiments are further described below with reference to the drawings.
