Description
Technical field
The present invention relates to a kind of optics imaging lens system group, particularly about a kind of miniaturization optics imaging lens system group that is applied on the portable electronic product.
Background technology
Recent years, along with the rise of the portable electronic product with capture function, the demand of miniaturization phtographic lens day by day improves; And the photo-sensitive cell of general phtographic lens is nothing more than being sensitization coupling element (Charge Coupled Device; CCD) or CMOS element (Complementary Metal-Oxide Semiconductor Sensor, CMOSSensor) two kinds, and progressing greatly along with semiconductor fabrication process technology; Make the Pixel Dimensions of photo-sensitive cell dwindle; The miniaturization phtographic lens is the development toward high pixel field gradually, therefore, and to the also increase day by day of requirement of image quality.
Tradition is equipped on the miniaturization phtographic lens on the portable electronic product; Many employing four-piece type lens arrangements are main; Like United States Patent (USP) the 7th, 365, shown in No. 920; Wherein first lens and second lens are to bind mutually and become Doublet (doublet) with two sheet glass spherical mirrors, in order to color difference eliminating.But the method has its shortcoming, one of which, and too much glass spherical mirror configuration makes degree of freedom in system not enough, causes the total length of system to be difficult for shortening; Its two, the manufacturing process that glass mirror binds is difficult for, and causes the difficulty in the manufacturing.In addition, United States Patent (USP) the 7th, 643 has disclosed the optical lens that a kind of four separate lenses constitute for No. 225, includes a plurality of non-spherical lenses, can effectively shorten the total length of system, and obtain good image quality.
But because intelligent mobile phone (Smart Phone) and PDA high standard running gears such as (Personal Digital Assistant) is in vogue; Drive miniaturization phtographic lens riseing rapidly on pixel and image quality; Existing four-piece type lens combination can't satisfy the more phtographic lens module of high-order; Add electronic product constantly toward high-performance and lightening trend development, be equipped with the important target that high pixel, high performance miniaturization phtographic lens have just like become the development of high-order electronic product.
In view of this, be badly in need of a kind of being applicable on frivolous, the portable electronic product, image quality is good and be unlikely to the optics imaging lens system group that makes the camera lens total length long.
Summary of the invention
The present invention provides a kind of optics imaging lens system group, comprises the lens of five pieces of tool refracting powers, by the thing side extremely as side is in regular turn: first lens of the positive refracting power of a tool, and its thing side surface is a convex surface; Second lens of the negative refracting power of one tool; One the 3rd lens, its thing side surface are convex surface and are concave surface as side surface; One the 4th lens, its thing side surface be all aspheric surface as side surface; And one the 5th lens, it is a concave surface as side surface, and the 5th lens be provided with at least one point of inflexion as side surface; Wherein, The thickness of the 4th lens on optical axis is CT4; The thickness of the 5th lens on optical axis is CT5; The distance of this aperture to this sense electronics optical element on optical axis is SL, and the distance of the thing side surface of these first lens to this sense electronics optical element on optical axis is TTL, satisfies following relationship formula: 0.8＜CT4/CT5＜1.5; And 0.7＜SL/TTL＜1.1.
In the optics imaging lens system group of the present invention, the positive refracting power of this first lens tool provides system required part refracting power, helps to shorten the total length of this optics imaging lens system group; This second lens tool is born refracting power, and the aberration that can be effectively these first lens of the positive refracting power of tool be produced is done revisal, and helps the aberration of update the system simultaneously; The 3rd lens can be negative refracting power lens or positive refracting power lens; When the 3rd lens tool was born refracting power, effectively the Petzval of update the system and number (Petzval Sum) made peripheral image planes become more flat; When the positive refracting power of the 3rd lens tool, then help the higher order aberratons of update the system.
In the optics imaging lens system group of the present invention, these first lens can be a biconvex lens or are that a thing side surface is convex surface and is the crescent lens of concave surface as side surface; When these first lens are a biconvex lens, can effectively strengthen the refracting power configuration of these first lens, and then make the total length of this optics imaging lens system group become shorter; When these first lens are the crescent lens of a convex-concave, then help the astigmatism (Astigmatism) of update the system.The thing side surface of the 3rd lens is convex surface and is concave surface as side surface that effectively the update the system aberration also can be strengthened the astigmatism that update the system produces, to improve the image quality of optics imaging lens system group.The 5th lens be concave surface as side surface; The principal point (Principal Point) that can make system helps shortening the optics total length of system, to keep the miniaturization of camera lens away from imaging surface; Further; The 5th lens are provided with the point of inflexion, and the light that can more effectively suppress from the axle visual field is incident in the angle on the photo-sensitive cell, and the aberration of further modified off-axis visual field.
The present invention can effectively dwindle the susceptibility of camera lens volume, reduction optical system through above-mentioned mirror configuration set mode, more can obtain higher resolving power.
