When selecting a window, users should consider whether its material transmission performance and the mechanical properties of the substrate meet the application requirements. The window will not change the magnification of the system and provides multiple optional anti reflective films that can be applied to ultraviolet, visible, or spectral light. Sapphire glass can be used as optical window lenses, lens protection lenses, observation windows, armor windows, wear-resistant windows/optical components, high-temperature and impact resistant optical windows, etc,Sapphire window panelIt has high transmittance in the ultraviolet/visible light/wavelength range, with a transmittance range of 170nm-5.5um, high temperature resistance (can be used for a long time at 1700 ℃), high hardness, corrosion resistance, acid and alkali corrosion resistance.

Adopting the following processing method: 1. Hydration polishing. The principle of hydrated polishing is that during the processing of ceramic polishing machine, the polishing disc rubs against the surface of sapphire, generating high temperature and high pressure at the contact point, activating the atoms on the surface of sapphire. By utilizing superheated steam molecules to interact with water on the surface, a hydration chemical reaction layer is formed at the interface. Then, with the help of superheated steam, the hydration layer on the surface of sapphire is removed by the frictional force between the two, thereby achieving ultra precision machining of the surface. 2. The principle of laser polishing and laser polishing of sapphire is: through the thermal and photochemical reactions between laser and sapphire, it can be divided into two methods: cold polishing and hot polishing. Cold polishing uses short wavelength lasers to chemically decompose and remove materials. After absorbing light molecules, the surface material structure of sapphire will be damaged, causing the surface material to detach and achieve material removal. Sapphire window thermal polishing generally uses continuous long wavelength lasers to remove surface components of materials through melting, evaporation, and other methods. However, its thermal temperature gradient is large, and thermal stress is high, which can easily lead to cracks, surface roughness, etc., making it more suitable for rough polishing. The cold polishing process has low thermal stress and rarely produces cracks, making it suitable for ultra precision polishing.

Sapphire window panels can be widely used in various fields such as security, car accessories, digital cameras, lasers, optical instruments, etc. With the continuous development of the market, the application of lens technology is also becoming increasingly widespread. The function of sapphire light window is to gather three rays of light together and project them out through the lens. The light emitted by the sapphire light window passes through a filter to filter out invisible light such as ultraviolet rays, which have a certain damaging effect on the liquid crystal film. The light is homogenized through two multi lenses. The prism between two mirrors is used for pre polarization of light, which can reduce light loss compared to an asymmetric lightbox without a prism. Next, the light is split into three primary colors, red, green, and blue, by a spectroscope and reflected onto the corresponding liquid crystal chips.
