Problems solved by technology

However, this method is not effective in terms of light intensity stability and light uniformity. If the beauty treatment time is too long, it may cause changes in the range of light emitted from the lens and light intensity due to changes in the parameters of the electronic device. skin damage
In addition, these beauty instruments will also be limited in terms of miniaturization technology

Abstract

The invention discloses a photonic crystal coating film lens. The photonic crystal coating film lens comprises a plate glass substrate and a photonic crystal film plated to one side of the plate glass substrate. The photonic crystal film comprises a bottom layer, a middle layer and an outer layer. The bottom layer is composed of titanium oxide layers and calcium fluoride layers all of which are alternately laid, the layer connected with the middle layer is one calcium fluoride layer, and the layer connected with the plate glass substrate is one titanium oxide layer. The middle layer is a zinc sulfide layer. The structure of the outer layer is symmetrical with the bottom layer. The photonic crystal coating film lens has the advantages that a photonic crystal structure and a film coating method thereof are studied, the photonic crystal structure only allows the light wave with the wavelength being 755 mm to pass through, the structure is simple, microminiaturization is convenient, functions are stable, the photonic crystal structure can serve as a lens of a beautifying instrument and overcome the defects of optical oneness and optical intensity stability of an ordinary optical beautifying instrument, and the skin is prevented from being hurt.

Description

technical field [0001] The invention relates to the field of photonic crystals, in particular to a photonic crystal coated lens and a preparation method thereof. Background technique [0002] At present, there are many optical beauty instruments on the market, such as photon skin rejuvenation instruments, laser beauty instruments, etc. Most of the probes of these beauty instruments use laser electronic probes. This method can also allow light in a certain wavelength range to shine through the lens. On the skin, and then achieve the effect of beauty. However, this method is not effective in terms of light intensity stability and light uniformity. If the beauty treatment time is too long, it may cause changes in the range of light emitted from the lens and light intensity due to changes in the parameters of the electronic device. Changes that cause skin damage. In addition, these beauty instruments will also be limited in terms of miniaturization technology. [0003] After ...
