Embodiment
Hereinafter, with reference to the accompanying drawings embodiment of the present disclosure is described in detail.But the disclosure can be implemented with multiple different form, and should not be construed as limited to the embodiment being set forth in this.On the contrary, provide these embodiments, make the disclosure to be thoroughly with complete, and the scope of the present disclosure fully will be conveyed to those skilled in the art.In the accompanying drawings, for clarity sake, the shape and size of parts may be exaggerated, and identical label will be used to indicate same or analogous element all the time.
Below by the term of definition about direction.Optical axis direction O refers to the vertical direction based on lens 100, and circumferencial direction refers to the circumferencial direction (comprising clockwise direction and counter clockwise direction) of lens 100.
Fig. 1 is the skeleton view of the lens according to exemplary embodiment of the present disclosure.
With reference to Fig. 1, the lens 100 according to exemplary embodiment of the present disclosure can comprise: lens effective surface 10, structure optical surface; Flange part 20, the lens component of structure lens effective surface 10 periphery.
Lens effective surface 10 refrangible is from the ambient light of object reflection.For this reason, lens effective surface 10 can have spherical shape or aspherical shape, and can have concave, convex shape or meniscus shape.
Flange part 20 can construct the lens component of lens effective surface 10 periphery, and can be formed continuously with lens effective surface 10.
Here, the front surface (thing side surface) of lens effective surface 10 is referred to as first surface 11, and the rear surface of lens effective surface 10 (surface, image side) is referred to as second surface 13.
Can be formed by plastics according to the lens 100 of the structure described above of exemplary embodiment of the present disclosure also can injection moulding in a mold.
Because ambient light is being refracted to form image, so make the center of first surface 11 and the center of second surface 13 in the injection molding process of lens 100 need to coincide with one another to increase resolution through while lens effective surface 10.
Usually, plastic lens be injected shaping after, remove lens be formed in mould introduced in the process of the part of the position of resin by it, may burr be there is in cut part.In addition, the risk that the inside surface with lens barrel is interfered by burr may be there is when plastic lens is inserted in lens barrel.
Usually, plastic lens is injected shaping by mould, to have the shape that its side surface is partially cut, thus addresses this problem.Therefore, predetermined space can be formed with between the side surface and the inside surface of lens barrel of plastic lens, to prevent from interfering between burr and the inside surface of lens barrel.
But the asymmetric shape making the profile of plastic lens have to be only partially cut as above in order to injected-formative plastic lens instead of circle, process the mould of injected-formative plastic lens by following two kinds of methods.
The lens effective surface of the formation plastic lens in processing mold and the part of flange part is come by diamond turning lathe.
In addition, the part of the side surface that the formation plastic lens carrying out processing mold by milling is only partially cut.
Reason for this situation is: because the plane of plastic lens as above has the asymmetric shape in center based on plastic lens, so be not easy to use common diamond turning lathe to carry out processing mold.
Therefore, the part of the side surface that the formation plastic lens usually carrying out processing mold by milling is only partially cut.But, when the mould by processing via two kinds of methods as above carrys out injection moulding lens, the center of the external diameter of the mould formed by milling may not overlapped each other with the center of the external diameter of the mould formed by diamond turning.
Therefore, the risk that the center at the center and second surface that may there is the first surface of plastic lens will not overlap each other.
In addition, because the dimensional accuracy of Milling Process is lower than the dimensional accuracy of diamond turning, so when plastic lens is inserted in lens barrel, the distribution of press-in use level can be increased.
But, in an exemplary embodiment of the disclosure, processed the mould of injection moulding lens 100 by diamond turning, make by the shaping lens of mold injects 100 plane usually can have circle.
In other words, when observing along optical axis direction O, the lens 100 shaping by mold injects can have circle usually.
Namely, because pass through via the single job operation of use (such as according to the lens 100 of exemplary embodiment of the present disclosure, diamond turning) mould processed and be injected shaping, so first surface 11 center of lens 100 and the center of second surface 13 can coincide with one another.
As mentioned above, lens 100 be injected by mould shaping after, need to cut through the part that it introduces resin, cut part may occur burr.Therefore, along the side surface of optical axis direction O part cutting lens 100, space can be avoided with what form burr.
Here, after lens 100 are shaping by mold injects, the plane of lens 100 can have circle usually, and can have the circle be only partially cut by extra cutting technique.
Therefore, the part of the side surface of the flange part 20 of lens 100 can have cut along optical axis direction O vertical surperficial 23.
Therefore, when observing along optical axis direction O, the lens 100 according to exemplary embodiment of the present disclosure can have the circle be only partially cut.Therefore, when lens 100 are inserted in lens barrel, the impact of burr can be reduced significantly.
As mentioned above, according to exemplary embodiment of the present disclosure, in the process manufacturing lens 100, the center of first surface 11 of lens 100 and the center of second surface 13 coincide with one another, thus can improve the resolution of lens 100, and significantly can be reduced in the impact cutting through the burr that may occur when it introduces the part of resin.
Meanwhile, the risk that may exist is: due to be injected at lens 100 shaping after, apply load, so will crack be there is in lens 100 to cut part cutting through when it introduces the part of resin.
In addition, because occur that the possibility of burr increases along with the increase of the area of part cut in lens, so need the area of the cut part reduced in lens 100 to suppress to occur crack and burr in lens 100.
