The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
(22) The features, principles, and other aspects of the present disclosure are described in detail below.
(23) An imaging lens assembly according to exemplary implementations of the present disclosure may include, for example, sixth lenses having refractive power, i.e., a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens. These six lenses are sequentially arranged from an object side to an image side along an optical axis.
(24) In an exemplary implementation, the first lens may have a positive refractive power; the second lens may have a negative refractive power, and an object-side surface thereof may be a concave surface and an image-side surface thereof may also be a concave surface; the third lens may have a positive refractive power, and an image-side surface thereof may be a convex surface; the fourth lens may have a negative refractive power, and an object-side surface thereof may be a concave surface; the fifth lens has a positive refractive power or a negative refractive power; the sixth lens has a positive refractive power or a negative refractive power. By properly controlling the refractive powers and surface shapes of the first lens to the fourth lens, the low-order aberrations of the system can be effectively compensated, so that the system has good imaging quality.
(25) In an exemplary implementation, each of an object-side surface and an image-side surface of the first lens may be a convex surface.
(26) In an exemplary implementation, an object-side surface of the third lens may be a concave surface.
(27) In an exemplary implementation, an image-side surface of the fourth lens may be a concave surface.
(28) In an exemplary implementation, an object-side surface of the sixth lens may be a concave surface.
(29) In an exemplary implementation, the imaging lens assembly of the present disclosure may satisfy 2.0≤f/ImgH≤3.0, where f is a total effective focal length of the imaging lens assembly, and ImgH is half of a diagonal length of an effective pixel area on an imaging plane of the imaging lens assembly. More specifically, f and ImgH may further satisfy 2.0≤f/ImgH≤2.5, for example, 2.27≤f/ImgH≤2.40. Satisfying the formula 2.0≤f/ImgH≤3.0 is beneficial to ensure the lens assembly have good imaging quality.
(30) In an exemplary implementation, the imaging lens assembly of the present disclosure may satisfy 8<f/T23<12, where f is the total effective focal length of the imaging lens assembly and T23 is a spaced distance along the optical axis between the second lens and the third lens. More specifically, f and T23 may further satisfy 9.5<f/T23<10.5, for example, 9.87≤f/T23≤10.15. By controlling the spaced distances between the lenses, the telephoto ratio of the imaging lens assembly can be effectively improved, the magnification of the imaging lens assembly on object can be increased, and the imaging quality can be improved.
(31) In an exemplary implementation, the imaging lens assembly of the present disclosure may satisfy 3<f12/CT1<4.5, where f12 is a combined focal length of the first lens and the second lens, and CT1 is a center thickness along the optical axis of the first lens. More specifically, f12 and CT1 may further satisfy 3.5<f12/CT1<4.5, for example 3.72≤f12/CT1≤4.15. By properly controlling the combined focal length of the first lens and the second lens, light deflection can be effectively controlled and the size of the front end of the system can be reduced.
(32) In an exemplary implementation, the imaging lens assembly of the present disclosure may satisfy 0.5≤(T45+T56)/ΣAT<0.9, where T45 is a spaced distance along the optical axis between the fourth lens and the fifth lens, T56 is a spaced distance along the optical axis between the fifth lens and the sixth lens, and ΣAT is a sum of spaced distances along the optical axis between any two adjacent lenses of the first lens to the sixth lens. More specifically, T45, T56 and ΣAT may further satisfy 0.5≤(T45+T56)/ΣAT<0.7, for example 0.57≤(T45+T56)/ΣAT≤0.63. The air intervals from the fourth lens to the sixth lens accounts for a larger proportion of the total air intervals of the system, which can effectively increase the total focal length of the lens assembly and also ensure the optical system to have a better ability of compensating chromatic dispersion.
(33) In an exemplary implementation, the imaging lens assembly of the present disclosure may satisfy 0.6<f/f3<1.0, where f is the total effective focal length of the imaging lens assembly, and f3 is an effective focal length of the third lens. More specifically, f and f3 may further satisfy 0.73≤f/f3≤0.99. By properly selecting the effective focal length of the third lens, the third lens may have a larger positive refractive power, which is advantageous to enable the optical system to have a better ability of compensating field curvature.
(34) In an exemplary implementation, the imaging lens assembly of the present disclosure may satisfy −1.5<f/f4<−1.0, where f is the total effective focal length of the imaging lens assembly, f4 is an effective focal length of the fourth lens. More specifically, f and f4 may further satisfy −1.37≤f/f4≤−1.15. By controlling the negative refractive power of the fourth lens to be within a suitable range, the total focal length of the lens assembly can be increased, and at the same time, the field curvature can be also compensated.
(35) In an exemplary implementation, the imaging lens assembly of the present disclosure may satisfy 0.5≤|f/f5|+|f/f6|<1.0, where f is the total effective focal length of the imaging lens assembly, f5 is an effective focal length of the fifth lens, and f6 is an effective focal length of the sixth lens. More specifically, f, f5 and f6 may further satisfy 0.53≤|f/f5|′|f/f6|≤0.84. By properly assigning the focal lengths of the fifth lens and the sixth lens, and controlling the refractive power of the rear end of the system to be within a smaller range, the deflection angle of the light can be reduced, thereby reducing the sensitivity of the system.
(36) In an exemplary implementation, the imaging lens assembly of the present disclosure may satisfy −1.5<R5/R8<−0.5, where R5 is a radius of curvature of an object-side surface of the third lens, and R8 is a radius of curvature of an image-side surface of the fourth lens. More specifically, R5 and R8 may further satisfy −1.42≤R5/R8≤−0.76. Properly setting the radius of curvature of the object-side surface of the third lens and the radius of curvature of the image-side surface of the fourth lens makes it is easier for the optical system to compensate field curvature and distortion.
(37) In an exemplary implementation, the imaging lens assembly of the present disclosure may satisfy 0<R6/R7<1.0, where R6 is a radius of curvature of an image-side surface of the third lens, and R7 is a radius of curvature of an object-side surface of the fourth lens. More specifically, R6 and R7 may further satisfy 0.3<R6/R7<0.7, for example, 0.38≤R6/R7≤0.61. By properly setting the radius of curvature of the image-side surface of the third lens and the radius of curvature of the object-side surface of the fourth lens, the optical system may have a larger aperture, and thereby improving the overall brightness of the image.
(38) In an exemplary implementation, the imaging lens assembly of the present disclosure may satisfy −1.0<f/R2<0, for example, f is an total effective focal length of the imaging lens assembly, and R2 is a radius of curvature of an image-side surface of the first lens. More specifically, f and R2 may further satisfy −0.6<f/R2<−0.1, for example, −0.56≤f/R2≤−0.21. Properly setting the radius of curvature of the first lens makes it is easier to compensate aberrations and improve the modulation transfer function (MTF) performance of the system.
(39) In an exemplary implementation, the imaging lens assembly of the present disclosure may satisfy |f/R9|+|f/R10|<1.2, where f is an total effective focal length of the imaging lens assembly, R9 is a radius of curvature of an object-side surface of the fifth lens, and R10 is a radius of curvature of an image-side surface of the fifth lens. More specifically, f, R9 and R10 may further satisfy 0<|f/R9|+|f/R10|<1.2, for example, 0.30≤|f/R9|+|f/R10|≤1.13. By properly setting the radius of curvature of the fifth lens to make its curved surface smooth, the total focal length of the lens assembly can be effectively increased. At the same time, by properly assigning the refractive power of the fifth lens, the sensitivity of the processing for actual components is advantageously reduced.
(40) In an exemplary implementation, the imaging lens assembly of the present disclosure may satisfy 0.5≤|f/R11|f/R12|<1.5, where f is an total effective focal length of the imaging lens assembly, R11 is a radius of curvature of an object-side surface of the sixth lens, and R12 is a radius of curvature of an image-side surface of the sixth lens. More specifically, f, R11 and R12 may further satisfy 0.50≤|f/R11|+|f/R12|≤1.36. By properly setting the radius of curvature of the sixth lens, the angle of the incident light and the angle of the emergent light for the sixth lens are advantageously adjusted, and the chief ray angle (CRA) of the optical system can be effectively controlled, which is more beneficial to the matching with the chips.
(41) In an exemplary implementation, the imaging lens assembly of the present disclosure may satisfy f/EPD<2.5, where f is a total effective focal length of the imaging lens assembly, and EPD is an entrance pupil diameter of the imaging lens assembly. More specifically, f and EPD may further satisfy 2.18≤f/EPD≤2.48. When the formula f/EPD<2.5 is satisfied, the system has the advantage of a large aperture, which can enhance the imaging effect of the system in a weak light environment, while reducing the aberrations at the edge field-of-view.
(42) In an exemplary implementation, the imaging lens assembly may further include at least one stop to improve the imaging quality of the imaging lens assembly. The stop may be disposed at any positions as needed, for example, the stop may be disposed between the object side and the first lens.
(43) Alternatively, the imaging lens assembly described above may further include an optical filter for correcting chromatic aberration and/or a protective glass for protecting a photosensitive element on the imaging plane.
(44) The present disclosure provides a long-focus lens assembly with six lens, this long-focus lens assembly can be used with other known wide-angle lens assemblies to form a dual-camera lens assembly, so as to achieve an ideal magnification and a good quality image under auto-focus. In addition, by properly disposing the refractive power, the surface shape, the center thickness of each lens, and spaced distances along the optical axis between the lenses, the size and the sensitivity of the long-focus lens assembly of the present disclosure can be effectively reduced, and the processability of the long-focus lens assembly can be improved, such that the long-focus lens assembly is more advantageous for production processing and can be applied to portable electronic products. Meanwhile, the long-focus lens assembly configured as described above may also have smaller aberrations and can match with high-resolution imaging chips.
(45) In the implementations of the present disclosure, most of the lenses employ aspheric surface. The aspheric lens is characterized by a continuous change in curvature from the center of the lens to the periphery of the lens. Unlike a spherical lens having a constant curvature from the center of the lens to the periphery of the lens, the aspheric lens has a better radius of curvature characteristic, and has the advantages of improving distortion aberration and improving astigmatic aberration. With aspheric lens, the aberrations that occur during imaging can be eliminated as much as possible, and thus improving imaging quality.
(46) However, it will be understood by those skilled in the art that the number of lenses constituting the imaging lens assembly can be varied to achieve the various results and advantages described in this specification without departing from the technical solution claimed by the present disclosure. For example, although the implementation are described by taking six lenses as an example, the imaging lens assembly is not limited to including six lenses. The imaging lens assembly can also include other numbers of lenses if desired.
(47) Specific embodiments applicable to the imaging lens assembly of the above implementations will be further described below with reference to the accompanying drawings.
