Abstract
The utility model discloses a collecting lens which belongs to the technical field of optical products. The utility model comprises a transparent body, wherein the bottom surface of the transparent body is a plane. The utility model is characterized in that the surface of a body of the transparent body is provided with a group of saw tooth-shaped slots which regard A as a center of a circle, wherein A, B1, C1, D1, E1, F1, G1, etc. are positioned on the same horizontal plane which is parallel to the bottom surface; A, B, C, D, E, F, G, etc. are positioned on the same spherical surface. The collecting lens nicely operates the principle of a Fresnel zone plate. The utility model has the advantages of good light gathering performance, simple preparation process, portability, durability and broad application. The utility model isn't easily broken.
Description
Technical field
The utility model belongs to the optical articles technical field, is specifically related to a kind of concentration piece.
Background technology
Design, manufacturing and the application of modern zone plate become the frontier of optical research, at present, China Fresnel zone plate applied research at the early-stage, the field of application is also more limited.A kind of Wave surface light focusing sheet is arranged in the prior art, and this concentration piece mainly comprises: a substrate and a corrugated slice layer, and substrate is provided with a upper surface and a basal surface, and this substrate can pass for light; Corrugated slice layer also is provided with a upper surface and a basal surface, can pass for light; The upper surface of this corrugated slice layer is arranged with several corrugated slices, and when uncured, the bottom that above-mentioned substrate surface is pasted on these several corrugated slices is to form a Wave surface light focusing sheet irritating that mould forms for this corrugated slice layer.Therefore, this corrugated slice laminar surface and substrate surface form the upper surface and the basal surface of this Wave surface light focusing sheet jointly.Complex manufacturing technology, the spotlight effect of existing concentration piece are also not satisfactory, and range of application is narrow.
The utility model content
It is good that the utility model aims to provide a kind of optically focused performance, and application is the technical scheme of concentration piece widely.
As everyone knows, have the lens of one or two arch spheres can produce the optically focused effect, so-called Fresnel zone plate is exactly the lens sphere complanation with projection, utilization Fresnel optical principle, convex lens are launched to shakeout, make planar lens, and do not lose the light-focusing function of convex lens.
Described a kind of concentration piece comprises transparent bodies, and the bottom surface is a plane, and it is characterized in that having on the described transparent bodies surface one group is the serrate groove in the center of circle with A, wherein A, B
1, C
1, D
1, E
1, F
1, G
1On the same surface level parallel with the bottom surface, A, B, C, D, E, F, G ... on same sphere.
Described concentration piece has used the principle of Fresnel zone plate well, has good optically focused performance, and manufacture craft is simple, and light durable, is difficult for fragmentation, applied range.

Fig. 2 is the local enlarged diagram of convex lens cross section structure.
Fig. 3 is the utility model plan structure synoptic diagram.
Embodiment
Now, the utility model is further specified in conjunction with Figure of description.
As shown in Figure 2, the sphere of convex lens is that the concentric circles in the center of circle is divided into some circle cambered surfaces deeply by one group with convex lens sphere summit A, and the concentric circle line direction density of cutting apart the convex lens sphere is big more, and it is thin more to cut apart the convex lens sphere, and degree of distortion is more little.The vertical-lift cambered surface makes cambered surface be in same surface level near the center of circle one side, and the bottom surface is done flat, promptly becomes concentration piece as shown in Figure 1.Transparent bodies 1 surface of this concentration piece is gone up and formed one group is the serrate groove 2 in the center of circle with A, wherein A, B
1, C
1, D
1, E
1, F
1, G
1On same surface level, A, B, C, D, E, F, G ... on same sphere, transparent bodies 1 bottom surface is the plane.The cross section of sawtooth groove 2 is similar to right-angle triangle, and its hypotenuse approximates the arc that the convex lens sphere is split to form, the hypotenuse lodging degree difference of serrate groove 2, and the serrate groove 2 near the center of circle is more flat and shallow more, on the contrary serrate groove 2 is sharp more and dark.Described transparent bodies 1 is rectangle or circle or ellipse or polygon.In the present embodiment, concentration piece adopts the PVC or the PET plastic sheet of good transmittance, is heating, under the pressurized conditions, is using mother matrix compression moulding.Concentration piece does not as described require to be made very thinly, also can adopt injection molding method to make.
This concentration piece has very strong optically focused effect, can be applicable to utilize the product of sun power, as energy-conservation products such as solar range, solar energy lamps, thereby saved the area of expensive solar panel greatly, made and utilize the product of sun power to be able to penetration and promotion; Also can be applicable to electric torch or other needs the product of optically focused.
