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, one skilled in the art will be understood that other possible implementation methods and advantages of the present invention.Figure
In component be not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
This specification sayed " lens have positive refractive index(Or negative refractive index)", refer to that the lens are located at optical axis
Near zone has positive refractive index(Or negative refractive index)For." the thing side of a lens(Or image side surface)Including positioned at certain region
Convex surface part(Or concave part)", refer to the region compared to radially close to the exterior lateral area in the region, towards parallel to optical axis
Direction more " outwardly convex "(Or " caving inward ")For.By taking Fig. 1 as an example, wherein I is for optical axis and this lens is with the light
Axle I be symmetry axis radially symmetrically, the thing side of the lens in a-quadrant there is convex surface part, B regions to have a concave part and C
Region has convex surface part, and reason is a-quadrant compared to radially close to the exterior lateral area in the region(That is B regions), towards parallel
In the direction of optical axis more outwardly convex, B regions then more cave inward compared to C regions, and C regions are compared to E regions
Similarly more outwardly convex." being located at circumference near zone ", refers to the curved surface only passed through for imaging light on lens
Positioned at circumference near zone, that is, the C regions in figure, wherein, imaging light includes chief ray(chief ray)Lc and edge

A-quadrant in region, that is, figure.Additionally, the lens also include an extension E, an optical imagery is loaded on for the lens group
In camera lens, preferably imaging light can't be by extension E, but the structure of extension E is not limited to this with shape, with
Under embodiment be the extension for asking accompanying drawing succinctly to eliminate 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
One first lens, one second lens, one the 3rd lens, one the 4th lens and one the 5th lens constituted, each lens all have
There is a refractive index, and towards thing side and make thing side that imaging light passes through and one towards image side and lead to imaging light with one
The image side surface crossed.Optical imaging lens of the invention only have foregoing five lens with refractive index altogether, each by designing
The design of the detail characteristic and relational expression of mirror, and the shooting angle and good optical property of broadness can be provided.Each lens it is thin
Portion's feature is as follows:The thing side of the first lens has a convex surface part for being located at optical axis near zone;The image side mask of the second lens
There is a concave part for being located at circumference near zone;The image side surface of the 3rd lens has a convex surface part for being located at optical axis near zone;
