Description

Technical Field

[0001] The present invention relates to the field of optics, and in particular to a processing technology for an optical waveguide lens template. Background Art

[0002] With the development of imaging display technology, the requirements for imaging characteristics are constantly increasing. In the air imaging technology, the light emitted from the projected object configured on one side of the optical waveguide lens is reflected by the mirror surface in the optical waveguide lens and simultaneously transmits the optical waveguide lens plane, so that the mirror image of the projected object is imaged as a real image in the air on the other side of the optical waveguide lens. The air imaging technology forms an image of the object in the air, so that people can see the image of the object without the help of auxiliary equipment such as VR glasses, giving people a strong visual shock effect, and attracting more and more people's attention and pursuit. However, the existing optical waveguide lens template is processed by mechanical processing, which has complex processes and high processing costs. The glossiness of the inner wall of the groove on the optical waveguide lens template is difficult to be processed into a mirror nanometer level. Summary of the invention

[0003] The purpose of the present invention is to improve the deficiencies of the prior art, provide a processing technology for an optical waveguide lens template with simple process, low processing cost and a groove inner wall glossiness reaching a mirror effect, and solve the deficiencies of the prior art.

[0004] In order to achieve the above object, the technical solution of the present invention is as follows:

[0005] A processing technology for an optical waveguide lens template, the processing technology comprises the following steps:

[0006] Step 1, in which a reflective lens with different heights is designed; the surface glossiness of the reflective lens reaches the mirror surface nanometer level;

[0007] Step 2, in which reflective lenses of different heights are closely stacked together to form a grooved optical waveguide lens template;

[0008] The third step is to fix the closely stacked reflective lenses and form the optical waveguide lens template.

[0009] In the first step, the thickness of the reflective sheets having different heights is also different.

[0010] The thickness of the reflective sheet with different heights in the first step is between 0.01 and 1 mm.

[0011] In the first step, the material of the reflective lens having different heights is resin, optical glass or metal.

[0012] The fixing method in the third step is to glue with photosensitive adhesive or heat-sensitive adhesive, clamp with a clamp, or fix with a frame.

[0013] The beneficial effects of the present invention are as follows: the present invention has a simple process and low processing cost, and adopts a method of closely fitting and stacking reflective lenses to process and manufacture a light waveguide lens template with grooves, so that the size of each groove is uniform and the error is small, thereby avoiding the error of mechanical processing. The glossiness of the inner wall of the groove can reach the mirror nanometer level, and the size of each groove can be reduced to the micrometer level, which can greatly improve the imaging resolution of the light waveguide lens product made of the light waveguide lens template, and truly achieve the purpose of high-definition aerial three-dimensional imaging.
