Specific embodiment

Before starting that the present invention is described in detail, first it is noted that in schema of the present invention, similar element be with It is identically numbered to represent.Wherein, this specification says its " lens have positive refractive index (or negative refractive index) ", refers to institute The refractive index on the optical axis that lens are come out using first-order theory theoretical calculation is stated as just (or being negative).The image side surface, the definition of object side For imaging light by scope, wherein imaging light include chief ray (chief ray) Lc and rim ray (marginal Ray) Lm, as shown in Figure 1, I is optical axis and this lens is radially symmetrical using optical axis I as symmetry axis, light passes through Region on optical axis is optical axis near zone A, rim ray by region be circumference near zone C, in addition, the lens also wrap Containing an extension E (i.e. the regions of circumference near zone C radially outward), an optical imaging lens are loaded on for the lens group Interior, being preferably imaged light can't be by extension E, but the structure of extension E is not limited to this with shape, below it Embodiment is the extension for asking schema that part is succinctly omitted.In more detail, face shape or optical axis near zone, circumference are judged The method of the scope of near zone or multiple regions is as follows：

Fig. 1 is refer to, is the sectional view of a lens radially.It is seen with the sectional view, is judging the model of aforementioned areas When enclosing, a central point is defined as the intersection point with optical axis on the lens surface, and a transfer point is on the lens surface A bit, it is and vertical with optical axis by a tangent line of the point.It it is sequentially first turn if there is a plurality of transfer points radially outward It changes a little, the second transfer point, and away from optical axis, radially farthest transfer point is N transfer points on effectively half effect footpath.Central point and Scope between one transfer point is optical axis near zone, and the region of N transfer points radially outward is circumference near zone, intermediate Different regions can be distinguished according to each transfer point.In addition, effective radius is in rim ray Lm and lens surface intersection to optical axis I Vertical range.

As shown in Fig. 2, the concave-convex system of the shape in the region is with parallel through the light in the region (or light extension line) and light The intersection point of axis determines (light focus decision procedure) in image side or object side.For example, after light is by the region, light It can be focused on towards image side, Focus Club's position R points in image side, such as Fig. 2 with optical axis, then the region is convex surface part.If conversely, light Behind certain region, light can dissipate, and the focus of extension line and optical axis is in object side, such as M points in Fig. 2, then the region is Concave part, so central point, to being convex surface part between the first transfer point, the region of the first transfer point radially outward is concave part；By Fig. 2 understands that the transfer point is the separation that convex surface part turns concave part, therefore can define the region and the radially adjacent region Inside region, be using the transfer point be boundary have different face shapes.In addition, if the face shape of optical axis near zone judges According to the judgment mode of usual skill in the field with R values (paraxial radius of curvature can be referred to, be often referred to saturating in optical software R values on mirror database (lens data)) positive negative judgement is concave-convex.For object side, when R values be timing, be determined as convex surface Portion when R values is bear, is determined as concave part；For image side surface, when R values be timing, be determined as concave part, when R values are negative When, it is determined as convex surface part, the bumps that the method determines are identical with light focus decision procedure.If without conversion on the lens surface Point, the optical axis near zone are defined as the 0~50% of effective radius, circumference near zone be defined as effective radius 50~ 100%.

The lens image side surface of Fig. 3 examples one only has the first transfer point on effective radius, then the firstth area is attached for optical axis Near field, the secondth area are circumference near zone.The R values of this lens image side surface judge that optical axis near zone is recessed with one for just Face；The face shape of circumference near zone is different with the inside region radially close to the region.That is, circumference near zone and optical axis The face shape of near zone is different；The circumference near zone system has a convex surface part.

The lens object side surface of Fig. 4 examples two has first and second transfer point on effective radius, then the firstth area is light Axis near zone, the 3rd area are circumference near zone.The R values of this lens object side judge optical axis near zone to be convex for just Face；Region (the secondth area) between first transfer point and the second transfer point has a concave part, circumference near zone (the 3rd area) With a convex surface part.

The lens object side surface of Fig. 5 examples three, without transfer point, is at this time with effective radius 0%~50% on effective radius Optical axis near zone, 50%~100% is circumference near zone.Since the R values of optical axis near zone are just, so object side exists Optical axis near zone has a convex surface part；And without transfer point between circumference near zone and optical axis near zone, therefore the neighbouring area of circumference Domain has a convex surface part.

As shown in fig. 6, optical imaging lens 1 of the present invention, from object side 2 to the image side 3 of imaging for placing object (not shown), Along optical axis (optical axis) 4, including at least having the first lens 10, the second lens 20, the 3rd lens 30, the 4th lens 40th, the 5th lens 50, the 6th lens 60, optical filter 90 and imaging surface (image plane) 91.Defined herein first lens 10 are The number of object side 2 to image side 3 carrys out first lens with refractive index, and the second lens 20 come second for the number of object side 2 to image side 3 to be had The lens of refractive index, the 3rd lens 30 carry out the 4th lens with refractive index for image side 3 to object side 2 number, and the 4th lens 40 are Image side 3 to object side 2 number, which carrys out three pieces, has the lens of refractive index, and the 5th lens 50 come second for image side 3 to object side 2 number to be had The lens of refractive index, the 6th lens 60 carry out first lens with refractive index for image side 3 to object side 2 number.It is, in general, that first Lens 10, the second lens 20, the 4th lens 40, the 5th lens 50, the 6th lens 60 can be by plastics or glass material institute It is made, but the present invention is not limited.3rd lens 30 are made with plastic material, help to make optical imaging lens lightweight simultaneously Reduce manufacture cost, while attainable cost invention good effects.
