Holographic anti-blue-ray thin film and making method thereof

Abstract

The invention discloses a holographic anti-blue-ray thin film and a making method thereof. The method comprises the following steps of S10, selecting a recording medium and recording light source of optical responses, and making a volume hologram; S20, calculating a Bragg reflection angle according to Bragg conditions and reproduction characteristics of the volume hologram; S30, making the reflective holographic anti-blue-ray thin film according to the Bragg reflection angle obtained in S20. The holographic anti-blue-ray thin film and the making method thereof have the advantages that the holographic anti-blue-ray thin film is simple to make and low in making cost, harmful short-wave blue rays can be effectively reflected, and meanwhile, the situation is avoided that the color of an object is distorted because beneficial long-wave blue rays are reflected, so that the holographic anti-blue-ray thin film helps people to use their eyes healthily.

Description

technical field [0001] The invention belongs to the technical field of preparation of optical eye protection films, and in particular relates to a holographic anti-blue light film and a production method thereof. Background technique [0002] With the rapid development of science and technology, electronic products have become an indispensable part of people's lives. There are more and more phenomena such as "head bowing" and "mobile phone dependence", and people's dependence on electronic products is also increasing; Long-term exposure to electronic screens is prone to eye fatigue, and the blue light emitted by electronic screens is even more likely to induce blindness and eye diseases. [0003] Short-wave blue light is light with a wavelength between 400nm-455nm and relatively high energy. Blue light within this wavelength, especially blue light with a wavelength between 442nm-445nm, will increase the amount of toxins in the macular area of ​​the eye, seriously threatening...

AI Technical Summary

Problems solved by technology

[0004] At home and abroad, anti-blue light lenses, anti-blue light glasses coatings, blue light absorbers, etc. are generally produced in the form of chemical processes. This kind of anti-blue light equipment made in the form of chemical processes can diffract harmful blue light At the same time, it is easy to reflect the blue light in the beneficial band, resulting in color distortion of the object, and in the process of long-term use, the chemical production materials will cause secondary damage to the eyes to a certain extent, and the production process technology is complicated and the production cost is high
