The SiS eye protection device is a composite of alkoxide and lyogel (10) gel). Although it has the advantages of eliminating static charge and absorbing low-frequency radiation, it is less obvious that the light of different wavelengths is different from that of absorbing strong light, reflected light and glare. In terms of types, the eye protection devices are mostly polarized lenses, the second is to remove the reflected light from the earth, and the part is removed from the horizontal direction. However, the conventional eye protection device has disadvantages such as unevenness, crease, Z, unevenness, bubble and blur, and the like, especially for different glare, cannot have a partial deflection effect.

FE003-P428-TW 6 M288479 A protective device consisting of optical and vo-emitting elements to overcome the disadvantages of the prior art. "Monthly reference to Fig. 1a' which shows the eye protection device 1〇0 described in the creation. The present invention proposes a protection device 100, which mainly comprises a transparent substrate 200 as a shame, and a plurality of light diffraction elements 3 are located on the surface of the transparent substrate 2 (9); wherein the plurality of optical diffraction elements The 300 series includes a plurality of light diffraction unit cells 320; and a flat surface of the plurality of light diffraction elements 3 is disposed on a surface of the transparent substrate 200. More specifically, the plurality of light diffractive elements are disposed on the first surface and the second surface of the transparent substrate 200 and are complementary to each other. Please refer to Figure lb, which shows an application of the eyepiece device 100 described herein. The eye protection device can be applied to any device capable of displaying an image, such as a television mirror or a mirror of a general display 110. Please refer to Fig. 2, which shows a detailed view of the side structure of the eye protection device and the light diffraction element. The basic principle of the light diffractive element (D〇E) 3〇〇 is the phase modulation method, which uses the scalar diffraction theory or the 畺 diffraction theory to calculate the surface profile. After the invention of holography, the concepts and principles of diffractive optics were further applied to micro-optical components; such as beamsplitters and lens sets. The basic design flow of the light diffraction element is to first calculate the interference pattern of a specific wavefront, which is a computer-generated h〇l〇gram (CGH). Then, the digital plotter output calculates the simulated interference pattern, and finally the miniature image is the final film.

FE003-P428-TW 7 M288479 The phase of the incident surface light field is modulated by the change of the surface porch, and the phase of the outgoing surface light field is controlled to obtain the distribution of the spatial energy of the predetermined outgoing light. Use Figure 2 to illustrate how to use it. Wherein λ1 and λ2 are incident light rays generally in different directions, and the light is scattered by the light diffraction element; λ3 is expressed as light emitted from the display by the light, and the optical path spacing is equal via the structure of the complementary light diffraction element. The light emitted from the display is not scattered by the light diffractive element. The design rule of the light diffractive element is roughly divided into four kinds of structures: the first is an optical path method; the second is a scalar diffraction theory; the third is Rigorous coupled wave theory; the fourth is effective medium theory. The current light diffraction elements are mostly designed using a scalar wave diffraction method. The scalar wave diffraction method is based on the phenomenon of light fluctuations and describes the diffraction phenomenon of light, also known as fourier optics. The fluctuation of light says that every point on the wavefront can be regarded as a secondary (sec〇ndary) spherical wave source, that is, the wave packets of all new wave sources will form a new wavefront. The optical diffraction element operates on the relationship between the refractive index n of the medium and the film thickness of the light diffraction element. The forward direction of the light passing through the light diffraction element is designed according to the wavelength of the incident light and the refractive index of the substrate. The diffraction efficiency is related to the number of light diffraction single crystal lattices 310 on the plurality of light diffractive elements 300. In general, the more orders of light are scattered around the early lattice 310 to achieve higher efficiency. It should be noted that for the convenience of design, the plurality of light diffractive elements 300 are

FE003-P428-TW 8 M288479 The number of light diffraction single το lattices 32 系 has an integer multiple of 2, and the plurality of light diffraction elements 300 are of a periodic structure. The plurality of light diffractive elements 3 厚度 have a thickness of no more than 1 〇 um and a diffraction angle of not more than 90 degrees. In the creation, the diffraction efficiency of a plurality of light diffractive elements is not more than 98%. Again with the second diagram to illustrate the process of the optical diffractive component 300, there are three major manufacturing methods for D:E: holographic recording, lithographic lithography (yellow lithography) process and direct recording. The preferred embodiment of the present invention is, but not limited to, a reticle lithography (yellow lithography) process. The transparent substrate 3 10 such as quartz, glass substrate, indium tin oxide thick film (IT.) or transparent photoresist is fabricated by a conventional mask lithography (yellow lithography) process. In order to fabricate 32 〇 of the light diffraction unit lattices of different depths, multiple κ photolithography and etching processes can be employed. Or use a gray scale reticle. Since the photoresist has different exposure depths at different color depths of the gray scale reticle, the diffraction grating unit lattice of different depths can be achieved. The photoresist is used but not limited to the AZ positive photoresist series and the Su_8 negative photoresist series. Other thick film photoresists can also be implemented. On the other hand, on the manufacturing process of the light diffraction element 300, a micro-electromechanical process technology, a semiconductor process technology or a quasi-molecular laser process can produce a nano-scale light diffraction element component. Due to the rapid development of micro-electromechanical (MEMS) technology and the need for miniaturization of components, the optical diffraction unit of the optical diffraction element 300 can also use the LIGA process of micro-electromechanical, that is, prior to 矽The substrate utilizes an upper semiconductor process to make a master mold similar to the light diffraction unit lattice 32〇. Put on

After the baking, the de-polymerized polymer PDMS or its phase diffraction elements are 〇. := A step of obtaining a thickness of about (10) is obtained, and a complementary type 4:: face is repeated to repeat the above-described process shooting element 300. The light diffractive element 3 is configured. The number of the optical windings is preferably two or two; the crystal= is a plain scanning surface having an integer of 2, and is a plurality of light diffractive elements of the white mouth. The surface. Compared with the traditional eye protection device, the device disclosed in the present invention has a light diffractive element, == mirror: has a hook, no scratch, no spots, and more; And does not affect the quality of the display and the contrast ratio 'f to effectively protect the user's eyes. Therefore, the effect of this creation (10) can be used to deflect the strong light of different wavelengths without affecting the image quality and contrast ratio of the mirror. It is to be understood that the above-described preferred embodiments are disclosed, and that it is not intended to be a substitute for the invention. As explained above, you can make corrections and changes for each type without breaking the spirit of ί. Therefore, the scope of protection of this creation is subject to the definition of Shenjing's patent scope attached to it.
