Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
Consult Fig. 2 and Fig. 3, shading array lens 100 of the present invention comprises: body 1, the effective district 2 of multiple optics, and a shading region 3.
This body 1 is made and comprises an end face 11 and a bottom surface 12 for plastic cement material, in this preferred embodiment, the material of this body 1 is optics plastic cement, the PMMA(polymethylmethacrylate that for example material business Mitsubishi is sold), the PC-AD5503(polycarbonate that sold of material business Supreme Being people), the ZEONEX480R that sold of material business ZEONEX, or the ULTEM-1010 that sold of material business SABIC etc.
Effective district (the ClearAperture of described optics, CA) 2 be arranged in this body 1, and this end face 11 extends to this bottom surface 12 certainly, light can pass through the effective district 2 of described optics, and the face shape in the effective district 2 of each optics can be the lens of spherical lens, non-spherical lens, free-form surface lens, planar lens or other shape kinds.
Because the present invention does not need to use any shade, therefore the design of the face shape in the effective district 2 of described optics is freely unrestricted, and existing use shade can be limited to the manufacturing process of shade and only have plane or simple sphere profile, thereby limited the face shape design in the effective district 2 of described optics.
This shading region 3 is arranged in this body 1 and around defining the effective district 2 of described optics, this shading region 3 comprises a carburization zone 31 that is processed to form and can be stopped light by laser 4, carbonization is to make non-carbon component in compound as hydrogen, oxygen, a kind of thermal treatment that nitrogen etc. are whole or large portion vapors away, in this preferred embodiment, this carburization zone 31 is to be formed between the end face 11 and bottom surface 12 of this body 1, because this carburization zone 31 is formed in the inside of this body 1, this carburization zone 31 thereby there is adeciduate advantage, in addition, the end face 11 that also can keep this body 1 is smooth with bottom surface 12, and can closely be close to while contributing to follow-up installation assembly.
It is worth mentioning that, as long as change the degree of depth that laser 4 energy focus on, this carburization zone 31 also can be formed on the end face 11, bottom surface 12 of this body.
Coordinate and consult Fig. 1, Fig. 2 and Fig. 4, the preferred embodiment of the manufacture method of shading array lens 100 of the present invention, sequentially comprises following steps:
Step 601: first, prepare an array lens 100 ', this array lens 100 ' has this body 1, the effective district 2 of described optics and this shading region 3, and now this shading region 3 is still not yet formed with this carburization zone 31.
Step 602: then, injection laser 4 in the scope of this shading region 3, forms this carburization zone 31 that can stop light in this shading region 3, and this array lens 100 ' is processed to form to this shading array lens 100.The degree of depth focusing on due to laser 4 energy is to control to focus between the end face 11 and bottom surface 12 of this body 1, and therefore can make this carburization zone 31 is to be formed between the end face 11 and bottom surface 12 of this body 1.
In this preferred embodiment, luminous point 5 diameters of laser 4 are about 0.06 ㎜, and output energy is 5W～30W, be preferably 30W, and laser 4 is continuous wave output laser, by controlling size, the depth of focus, the output energy of laser 4 luminous points 5, can form this good carburization zone 31 of quality.
In sum, effect of the present invention is:
One, compared to existing stamping forming entity shading aperture easily because of the small shortcoming thrusting of size between the effective district 2 of described optics, these carburization zone 31 Stability Analysis of Structures that the present invention uses laser 4 to be processed to form, and luminous point 5 diameters of laser 4 are about 0.06 ㎜, output energy is 30W, is more applicable for minute sized shading array lens 100.
Two, compared to existing impression, be coated with tool inking transfer printing shading colloid, there is necessary precision positioning, photomask thickness and be difficult to control, in on-plane surface region, will be difficult to the shortcomings such as impression, the present invention uses laser 4 processing to be more prone to location, and easily control this carburization zone 31 that forms thickness homogeneous, and because the depth of focus of laser 4 is easy to adjust, therefore can be suitable for this carburization zone 31 that is processed to form in on-plane surface region.
Three, in existing mould, implant in advance the light shield layer method of ejection formation lens again, penetrate material melting point difference, process temperatures difference, make processing procedure complexity, cost is high and yield is low, and the present invention uses laser 4 processing can simplify processing procedure, reduce costs, improve yield.
Four, compared to the whole bag of tricks of existing use photoetch, all belong to wet process, and have, necessary precision positioning, man-hour are long, high in cost of production shortcoming, the present invention uses laser 4 to belong to dry process, aforesaid drawbacks can be improved, and the effective district 2 of optics described in the material damage in the various wet process of photoetch can be avoided.
