Specific embodiment
Below with reference to attached drawing, the preferred embodiment of the utility model is described in detail, the utility model is done and is further explained
It states.
Firstly, will include a pair of light-transmissive in conjunction with the description of Fig. 1 ~ 8 according to the optical imaging element 1 of the utility model embodiment
Laminated body 2 and the second adhesive layer 3, the second adhesive layer 3 are arranged between a pair of light-transmissive laminated body 2, bond a pair of light-transmissive laminated body
2.Wherein, light transmission laminated body 2 includes: several clear bars 21, clear sheet 22, the first adhesive layer 23, a pair of light-transmissive laminated body 2
It fits closely, as shown in figure 8, the direction of the internal reflection surface of a pair of light-transmissive laminated body 2 forms orthogonal arrangement, to guarantee to pass through light
The reflection for studying element can be realized in kind and real image face-to-face symmetrical, it is ensured that the imaging effect of optical imaging element 1.
Specifically, as shown in Fig. 6 ~ 7, the single or double of clear bar 21 is equipped with metallic reflector 211, and several transparent
Item 21 fits closely, and the binding face between clear bar 21 does not smear jointing material and is the face equipped with metallic reflector 211.?
In the present embodiment, metallic reflector 211 is made of the titanium of high reflectance, tin, chromium, aluminium or silver.
Specifically, shown in Fig. 4 ~ 7, clear sheet 22 is covered in several clear bars 21 fitted closely, clear sheet
22 is vertical with the binding face of several clear bars 21, i.e., vertical with metallic reflector 211, to guarantee the reflected light path of light.?
In the present embodiment, the material of clear bar 21 and clear sheet 22 is glass or organic glass or resin material, clear bar 21 and thoroughly
The material of isotropic disk material 22 can be identical or not identical, further, according to specific environment and application scenarios, every piece of clear sheet 22
Thickness range is 0.2mm ~ 8mm, substantially improves mechanical property and thermal property, improves the ability for resisting environmental change.
Specifically, shown in Fig. 4 ~ 5, clear sheet 22 is arranged in and several clear bars fitting closely in the first adhesive layer 23
Between 21, the first adhesive layer 23 bonds clear sheet 22 and several clear bars 21.In the present embodiment, 23 He of the first adhesive layer
Second adhesive layer 3 is macromolecule sticker or transparent double-side glue, wherein macromolecule sticker can UV or heat cure, and viscosity
Suitably.Further, the first adhesive layer 23 is not identical or identical with the material of the second adhesive layer 3, and the first adhesive layer 23 and second is viscous
Close layer 3 with a thickness of 5 μm ~ 2mm.
As shown in Figure 1, manufacturing process comprises the following steps according to the optical imaging element of the utility model embodiment:
By several according to specification requirement cutting 21 proper alignment of clear bar and be bonded to each other, be not necessarily between clear bar 21
