Embodiment Construction

[0055] Relevant detailed description and technical contents of the present invention are as follows with regard to coordinating accompanying drawings now:

[0056] Such as figure 1 and figure 2 As shown, it is the first embodiment proposed by 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, a spacer layer 30, A second lens 40 and a third lens 50 .

[0057] 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 transmittance, And the sphere 10 has a first refractive index.

[0058]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 ...

Abstract

The invention provides a lens structure made of materials with different refractive indexes. The lens structure comprises a spherical sphere having a first portion and a second portion, a first lens formed at the first portion, a spacing layer formed between the sphere and the first lens, a second lens formed at the second portion, and a third lens formed on the second lens and opposite to the sphere. The first lens, the second lens and the third lens are respectively made of materials with different refractive indexes; and light-receiving curved surfaces with different curvatures are formed on the lenses, so that light passes through the light-receiving curved surfaces to form multi-times light collecting effects.

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...
