1. What is a Nanomirror
Center for Optoelectronics, Nanostructures and Semiconductor Processes at the University of California, Berkeley. The mirror is only 0.23 microns thick and has a reflectivity of over 99.9 percent. The manufacturing process is simple and the cost is low. For any laser, the mirror used to form the laser cavity is a very critical component. For example, high-reflecting mirrors used in vertical-cavity surface-emitting lasers (VCSELs) achieve 99 percent reflectivity. The mirrors used in such laser devices are called distributed Bragg reflectors (DBRs). The mirror is typically constructed of two materials with different refractive indices that are grown alternately to form a structure with multiple layer pairs. The reflective performance of a DBR lens is determined by the number of layers in the structure, the thickness of each layer, the refractive indices of the two materials used in the structure, and the absorption and scattering properties of each layer. In general, the greater the difference in refractive index between the two materials that make up a DBR layer pair, the higher the reflectivity of the layer pair. Therefore, in order to achieve the above-mentioned high reflectivity, how to select two materials with large differences in refractive index, etc., the entire production process is very complicated, and the production cost is also greatly increased. In addition, although the reflectivity between the two layers is high, when the number of layers that make up the lens reaches 80 layers with a thickness of 5 microns, the reflectivity is greatly reduced.
2. The advantages of nanomaterials
High temperature, high hardness and high strength are the eternal themes of the development of structural materials. The hardness (or strength) of nanostructured materials is inversely proportional to the particle size (in accordance with the Hall-Retch relationship). The refinement of material grains and the existence of high-density interfaces will definitely have a great impact on the mechanical properties of nanomaterials. In nanomaterials, the dislocation density is very low. The Frand-Reed model is adopted for dislocation slip and propagation. The diameter of the critical dislocation circle is larger than the nanocrystalline grain size. The grain size is large, so the slip and proliferation of dislocations in nanomaterials do not occur, which is the nanocrystal strengthening effect.
3. Nanomirror film produced by Brisafe
The lighter mirrors are mdae of 0.04mm nanomirror film instead of glass material. It's the best mirror you've ever seen. Totally distortion-free, chromatic aberration, ultra-light and shatter-proof. Non-glass technology improvement Made of 0.04mm polymer mirror mask - soft and elastic to the touch, we produce mirrors that change the way mirrors are used in the past, forget about the heavy and fragile problem of glass mirrors.
Brisafe lighter mirror does not use glass material, but uses 0.04mm nano mirror film. Lighter mirrors reduce personal injury issues through innovative technology.
