Embodiment Construction

[0065] Relevant detailed description and technical contents of the present invention are as follows with regard to coordinating accompanying drawings now:

[0066] like figure 1 and figure 2 Shown is the first embodiment of the present invention. The present invention is a lens structure made of materials with different refractive indices. The lens structure includes a sphere 10 , a first lens 20 and a spacer layer 30 .

[0067] Specifically, the sphere 10 has a first part 11 and a second part 12 integrally connected with the first part 11, the first part 11 and the second part 12 form a spherical shape and have light transmission, And the sphere 10 has a first refractive index. The first lens 20 is formed on one side of the sphere 10, and the first lens 20 is adjacent to the first part 11 of the sphere to form a first fitting groove 21 for the first part 11 to be embedded. , make the first part 11 embedded in the first fitting groove 21, make the second part 12 of the sph...

Abstract

The invention provides a lens structure made of materials with different refractive indexes. The lens structure comprises a sphere, a first lens, and a spacing layer formed between the sphere and thefirst lens. The sphere and the first lens have different refractive indexes; and the sphere is in a spherical shape. The first lens is formed on the sphere and thus the part of sphere is exposed out of the first lens; and the first lens has a first light-receiving curved surface. The spacing layer has a light-transmissive section opposite to the first light-receiving curved surface. After light forms a first light collecting effect through the second part of the sphere and enters the inside of the sphere, the light passes through the light-transmissive section to enter the first lens and a second light collecting effect is formed by the first light-receiving curved surface.

Description

technical field [0001] The present invention relates to a lens structure, in particular to a lens structure with high coaxiality and made of materials with different refractive indices. Background technique [0002] The optical lens has gradually developed from a single lens to a multi-lens, nothing more than to meet the special requirements of light propagation, and use multi-lens to change the optical path to eliminate aberration and spherical aberration. However, in this way, the lenses need to be sequentially assembled on a frame, which is not only cumbersome to assemble, but also wastes a lot of space. In addition, in the composition of the multi-lens, each lens needs to meet high coaxiality to avoid the deviation of the optical axis. [0003] In order to improve the above problems, such as China Taiwan Announcement No. I356760 Invention Patent Case, discloses a laminated lens and its manufacturing method and manufacturing device, including an optical axis, more than o...
