Embodiment
For being illustrated more clearly in the present invention, hereby lifting preferred embodiment and coordinate diagram to be described in detail as follows.
Refer to Fig. 2 to Figure 11, the manufacture method of the multiple field lens set 1 of preferred embodiment of the present invention, includes the following step:
A. place the eyeglass material 10 of melting on a basic mode 100 (as Fig. 2), in the present embodiment, this eyeglass material 10 is to select the epoxy resin (epoxy) with ultraviolet light polymerization characteristic, and after solidifying, transmittance is greater than 95%, refractive index is between 1.2～2.0; Afterwards, with transparent mould 110, compress the eyeglass material 10 of this melting, and with the eyeglass material 10 of this melting of UV-irradiation, in order to solidify the eyeglass material 10 (as Fig. 3) of this melting, to form a mirror plate layers 11; Then, this mirror plate layers 11 is separated with mould 110.
B. in this mirror plate layers 11, plate and establish after one deck infrared ray filter coating 50 (as Fig. 4), place the separating material 20 of melting in this mirror plate layers 11 (as Fig. 5), in the present embodiment, this separating material 20 is to select epoxy resin equally, but the refractive index after solidifying and the refractive index of this mirror plate layers 11 are unequal, and are less than 0.5 with the refringence of this mirror plate layers 11; Afterwards, with transparent mould 120, compress the separating material 20 of this melting, and with the separating material 20 of this melting of UV-irradiation, in order to solidify the separating material 20 (as Fig. 6) of this melting, to form one deck wall 21 in this mirror plate layers 11, then, the wall 21 forming is separated with mould 120;
C. place the eyeglass material 30 of melting on this wall 21 (as Fig. 7), and with transparent mould 130, compress after the eyeglass material 30 of this melting, eyeglass material 30 with this melting of UV-irradiation, in order to solidify the eyeglass material 30 (as Fig. 8) of this melting, to form again one deck mirror plate layers 31 on this wall 21, then, the mirror plate layers 31 forming is separated with mould 130;
D. in this mirror plate layers 31, arrange after one deck supporting layer 40 (as Fig. 9), this supporting layer 40 of etching, make only this mirror plate layers 31 (as Figure 10) of shaded portions of this supporting layer 40, afterwards, this mirror plate layers 11 is separated with this basic mode 100, to obtain one, have after the mirror plate layers 11,31 of mutual storehouse and the complex optics plate 200 of wall 21, then, the shelter of this supporting layer 40 of take cuts this complex optics plate 200 as benchmark, to obtain a plurality of multiple field lens set 1 (as Figure 11).
Please refer to the drawing 12, the multiple field lens set 1 that said method is made includes one first eyeglass 15, a sept 25, one second eyeglass 35 and the support member 45 sequentially connecting.Wherein, this first eyeglass 15 is to form after 11 cuttings of this mirror plate layers, and is coated with this infrared ray filter coating 50 on the minute surface that is connected with this sept 25 of this first eyeglass 11.
This sept 25 is with thickness, to be greater than these wall 21 cutting formation of 1 micron (μ m), and the object that design thickness is greater than 1 micron, be when light passes this sept 25, can be subject to the material of this sept 25 to affect to reach the effect that changes optical characteristics.
35, this second eyeglass is to form after these mirror plate layers 31 cuttings.
This support member 45 is to form after these supporting layer 40 cuttings, and is positioned at around the minute surface of this second eyeglass 35, and can be used as the use supporting with light path adjustment.
Thus, see through low-refraction poor (the being less than 0.5) design between described eyeglass 15,35 and this sept 25, just can reduce the side-play amount of light when change of medium, and then significantly promote the whole penetrance of light when this multiple field lens set 1, and reduce after the side-play amount of light, just the spacing can not must increasing between this first lens 15 and this second lens 15 is proofreaied and correct, and then can reach the object of Miniaturization Design.
In addition, see through this infrared ray filter coating 50, will make this multiple field lens set 1 can the unnecessary infrared ray of filtering, and then promote the optics effect school energy of this multiple field lens set 1.
Moreover, in the manufacturing process of this multiple field lens set 1, seeing through selects the epoxy resin of specific refractive index to form this mirror plate layers 11,31 and this wall 21, and each mirror plate layers 11,31 also can be selected the mode of the epoxy resin of different refractivity, just the light path of light in this multiple field lens set 1 can be effectively controlled, and then this multiple field lens set optical performance can be promoted significantly.
It is worth mentioning that, also can include the step of a making basic mode 100 before steps A: the plastic 102 of first placing melting is on a substrate 101 after (as Figure 13), and with mould 140, compress and solidify the plastic 102 (as Figure 14) of this melting, then, plastic 102 after solidifying is separated with mould 140, the basic mode being used to form steps A.Thus, just can utilize and make this basic mode 100 by this plastic 102 is moulding, and can worry to use fixed mould and have mould consume and eliminate the problem of changing, and then can reduce the cost while making.Certainly, use fixed mould as basic mode, can reach object of the present invention equally.
In addition, this infrared ray filter coating 50, except plating is established in above-mentioned steps B, also can change in step C or step D and plate and establish, and this infrared ray filter coating 50 is positioned on another minute surface of this first eyeglass 15 or the minute surface of the second minute surface 35.And should be noted that, under the condition of some optical design, even if this infrared ray filter coating 50 or this supporting layer 40 are not set, also can reach object of the present invention.
Moreover the design of above-mentioned each eyeglass 15,35 minute surfaces also can be used different moulds according to user demand, and can be concave surface, convex surface, plane, sphere or aspheric surface.
Except above-mentioned two lens structural design, again before step D, according to demand repeated execution of steps B and step C, and make the multiple field lens set obtaining after cutting, be also three-chip type or three above structures.In addition, above-mentioned eyeglass material 10,30 and separating material 20 be except being used the epoxy resin of ultraviolet light polymerization characteristic, also can select other refractive index to be greater than 1 photo-curing material and replace.Moreover, the foregoing is only the better possible embodiments of the present invention, such as apply instructions of the present invention and claim institute equivalent structure and method variation for it, ought to be included in the scope of the claims of the present invention.
