Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.
Furthermore, the terms "long", "short", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention, but do not indicate or imply that the referred devices or elements must have the specific orientations, be configured to operate in the specific orientations, and thus are not to be construed as limitations of the present invention.
A high-definition optical image capturing lens comprises a diaphragm, a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens which are sequentially arranged along the direction from an object side to an image side, wherein all surfaces from the object side surface of the first lens to the image side surface of the sixth lens are aspheric.
Specifically, the bending force and the surface type matching of each surface type are as follows:
the first lens element with positive refractive power has a convex object-side surface and a concave image-side surface at a paraxial region;
the second lens element with negative refractive power has a convex object-side surface and a concave image-side surface at a paraxial region;
the third lens element with positive refractive power;
the fourth lens element with negative refractive power has a convex object-side surface and a concave image-side surface at a paraxial region;
the fifth lens element with positive refractive power has a concave object-side surface at a paraxial region and a convex image-side surface at a paraxial region;
the sixth lens element with negative refractive power has a concave object-side surface and a concave image-side surface at a paraxial region.
The high-definition optical image capturing lens meets the following relational expression: 7.2 < fx (TTL/ImgH) < 8.0; wherein f is the focal length of the high-definition optical image capturing lens, TTL is the total optical length of the high-definition optical image capturing lens, and ImgH is half of the diagonal length of the effective pixel area on the imaging surface of the high-definition optical image capturing lens. The high-definition optical image capturing lens has the advantages of being large in image surface, light and thin in size and good in resolving power at the same time by limiting the focal length, the total optical length and the effective pixel area of the high-definition optical image capturing lens, and therefore market requirements are met.
Further, the high-definition optical image capturing lens further satisfies the following relation: f/f1+ f/f5 is more than 2.1 and less than 2.7; wherein f1 is the focal length of the first lens, and f5 is the focal length of the fifth lens. By limiting the sum of the ratio between the front end lens and the focal length between the rear end lens and the focal length of the high-definition optical image capturing lens, the contribution of the spherical aberration of the front end lens and the spherical aberration of the rear end lens can be controlled within a reasonable range, so that the imaging quality of the high-definition optical image capturing lens in an on-axis field area is effectively improved, and the high-definition optical image capturing lens is favorable for realizing the resolution of 4K.
Further, the high-definition optical image capturing lens further satisfies the following relation: f4/f6 is more than 13.9 and less than 15.1; wherein f4 is the focal length of the fourth lens, and f6 is the focal length of the sixth lens. By limiting the ratio of the focal length between the fourth lens and the sixth lens, the imaging angle of the high-definition optical image capturing lens is increased, so that the large-range view finding effect is achieved, and the imaging surface is further increased.
Further, the high-definition optical image capturing lens further satisfies the following relation: f3/f1-f4/f2 is more than 4.0 and less than 7.6; wherein f1 is the focal length of the first lens, f2 is the focal length of the second lens, f3 is the focal length of the third lens, and f4 is the focal length of the fourth lens. By satisfying the above relation, the assembling sensitivity of the high-definition optical image capturing lens can be reduced.
Further, the high-definition optical image capturing lens further satisfies the following relation: f1/R11 is more than 2.0 and less than 2.5; wherein f1 is the focal length of the first lens, and R11 is the curvature radius of the object-side surface of the first lens. Therefore, the reasonable distribution of the surface type and the focal length of the first lens is realized, and the optical system has better imaging quality and lower sensitivity.
Further, the high-definition optical image capturing lens further satisfies the following relation: f/R62 is more than 0.7 and less than 1.7; wherein R62 is a radius of curvature of the image-side surface of the sixth lens element. The shape of the sixth lens is regulated by the conditional expression, so that the light beam deflection degree is reduced, and the purpose of reducing aberration is achieved.
Further, the high-definition optical image capturing lens further satisfies the following relation: R41/R42 is more than 1.5 and less than 3.5; wherein R41 is a radius of curvature of the object-side surface of the fourth lens element, and R42 is a radius of curvature of the image-side surface of the fourth lens element. Therefore, the field curvature of each view field in the fourth lens is balanced in a reasonable range, and the high-definition optical image taking lens has better imaging quality.
Further, the high-definition optical image capturing lens further satisfies the following relation: 2.7 < ImgH/Fno; wherein ImgH is a half of a diagonal length of an effective pixel area on an imaging surface of the high-definition optical image capturing lens, and Fno is an aperture value of the high-definition optical image capturing lens. When the relation is satisfied, the ultra-large-size photosensitive surface of the high-definition optical image capturing lens is facilitated to be realized, and the high-definition optical image capturing lens has the characteristic of large aperture.
Further, the high-definition optical image capturing lens further satisfies the following relation: 5.0 < f × tan (HFOV) < 5.7; the HFOV is a half field angle of the high-definition optical image capturing lens. By means of the relational expression, the relation between the effective focal length and the view field angle of the high-definition optical image capturing lens can be limited, and the aspheric lens is matched, so that the chromatic aberration, the spherical aberration and the distortion of the high-definition optical image capturing lens can be balanced, and good imaging quality can be obtained.
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
