Specific embodiment
To further illustrate each embodiment, the present invention is provided with accompanying drawing.These accompanying drawings are the invention discloses one of content
Point, it is mainly used to illustrate embodiment, and the associated description of specification can be coordinated to explain the operation principles of embodiment.Coordinate ginseng
These contents are examined, those of ordinary skill in the art will be understood that other possible implementation methods and advantages of the present invention.In figure
Component be not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
" lens have positive refractive index (or negative refractive index) " described in this specification refers to the lens with Gauss light
The refractive index on optical axis that theory is calculated is for just (or being negative).The image side surface, thing side are defined as imaging light and pass through
Scope, wherein imaging light include chief ray (chief ray) Lc and rim ray (marginal ray) Lm, such as Fig. 1
Shown, I is for optical axis and this lens is radially symmetrical by symmetry axis of optical axis I, and light is by the region on optical axis
It is optical axis near zone A, the region that rim ray passes through is circumference near zone C, additionally, the lens also include an extension E
(i.e. circumference near zone C regions radially outward), with so that the lens group is loaded in an optical imaging lens, preferably into
As light can't be by extension E, but the structure of extension E is not limited to this with shape, and embodiment below is to ask
Accompanying drawing succinctly eliminates the extension of part.In more detail, judge face shape or optical axis near zone, circumference near zone,
Or the method for the scope in multiple regions is as follows：
As shown in figure 1, it is lens sectional view radially.From the point of view of with the sectional view, the model of aforementioned areas is being judged
When enclosing, it is the intersection point on the lens surface with optical axis to define a central point, 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.If there are multiple transfer points radially outward, the first conversion is sequentially
Point, the second transfer point, and away from the radially farthest transfer point of optical axis be N transfer points on effectively half effect footpath.Central point and first
Scope between transfer point is optical axis near zone, and N transfer points region radially outward is circumference near zone, and centre can
Different regions are distinguished according to each transfer point.Additionally, effective radius is hanging down on rim ray Lm and lens surface intersection to optical axis I
Straight distance.
As shown in Fig. 2 it is with parallel through the light in the region (or light extension line) and light that the shape in the region is concavo-convex
The intersection point of axle is determined (light focus decision procedure) in image side or thing side.For example, when light is by behind the region, light
Can be focused on towards image side, the 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
By the way that behind certain region, light can dissipate, the focus of its extension line and optical axis M points in thing side, such as Fig. 2, then the region be
Concave part, so central point is to being convex surface part between the first transfer point, the first transfer point region radially outward is concave part；By
Fig. 2 understands that the transfer point is the separation that convex surface part turns concave part, therefore the definable region and the radially adjacent region
Inner side region, with the transfer point be boundary have different face shapes.If in addition, the face shape judgement of optical axis near zone can
According to the judgment mode of those of ordinary skill in the field, (refer to paraxial radius of curvature, be often referred to saturating in optical software with R values
R values on mirror database (lens data)) positive negative judgement is concavo-convex.For with thing side, when R values are timing, it is judged to convex surface
Portion, when R values are to bear, is judged to concave part；For with image side surface, when R values are timing, it is judged to concave part, when R values are negative
When, it is judged to convex surface part, it is concavo-convex identical with light focus decision procedure that the method is determined.
If without transfer point on the lens surface, the optical axis near zone is defined as the 0~50% of effective radius, near circumference
Region is defined as the 50~100% of effective radius.
Fig. 3 is that the lens image side surface of the first example only has the first transfer point on effective radius, then the firstth area is light
Axle near zone, the secondth area is circumference near zone.The R values of this lens image side surface judge that optical axis near zone has for just
One concave part；The face shape of circumference near zone is different with the inside region radially close to the region.That is, circumference near zone and
The face shape of optical axis near zone is different；The circumference near zone has a convex surface part.
Fig. 4 is that the lens thing side surface of the second example has first and second transfer point on effective radius, then the firstth area
It is optical axis near zone, the 3rd area is circumference near zone.The R values of this lens thing side judge optical axis near zone for just
It is convex surface part；Region (the secondth area) between the first transfer point and the second transfer point has a concave part, circumference near zone the (the 3rd
Area) there is a convex surface part.
Fig. 5 be the 3rd example lens thing side surface on effective radius without transfer point, now with effective radius 0%~
50% is optical axis near zone, and 50%~100% is circumference near zone.Because the R values of optical axis near zone are just, so thing
Side has a convex surface part in optical axis near zone；And without transfer point, therefore circumference between circumference near zone and optical axis near zone
Near zone has a convex surface part.
Optical imaging lens of the invention, are a tight shots, and are sequentially set along an optical axis by from thing side to image side
An aperture, one first lens, one second lens, one the 3rd lens, one the 4th lens and one the 5th lens constituted, it is each
Lens all have refractive index and towards thing side and make thing side that imaging light passes through and one towards image side and make imaging with one
The image side surface that light passes through.Optical imaging lens of the invention only have foregoing five lens with refractive index altogether.Wherein
