Sapphire camera protection film manufacturers

Sapphire camera protection film *

SAPPHIRE glass (SAPPHIRE CRYSTAL) generally refers to the artificial synthesis of SAPPHIRE, and people usually understand jewelry - natural SAPPHIRE has a great difference, generally used in the manufacture of watch mirror. It and tungsten titanium alloy and high-tech ceramics are wear - resistant materials. Although these materials are resistant to abrasion, they will not be able to cause the disturbance of Li, and may be scratched by materials of equal or higher hardness (e.g., grindstone, sandpaper, nail file, granite surface, concrete walls and floors).

Sapphire is corundum gemstone in addition to red ruby, other colors corundum gemstone general name, the main component is alumina (Al2O3). Sapphire glass refers to synthetic sapphires that can be easily and cheaply produced in the laboratory as gem-grade sapphires with the same chemical composition and physical properties as natural sapphires.

Sapphire camera protection piece advantages:

1. Peak visible light transmittance 99% and average visible light transmittance more than 95%, which greatly improves the original brightness of LCD and PDP, and JIANGDI energy consumption;

2, the average reflectance is less than 4%, the low value is less than 0.5%, effectively weaken the defect caused by the strong light behind the picture turning white, enjoy a clearer image quality;

3, the color is more gorgeous, the contrast is stronger, the image color contrast is more intense, the scene is more clear;

4, Kangziweixian, effective protection of eyes UV spectrum transmittance large jiangDI, can effectively prevent UV damage to the eyes;

5, high temperature resistant AR glass temperature resistance >500 degrees (general acrylic can only withstand 80 degrees);

6. Good scratch resistance and wear resistance;

7, can be resistant to a variety of cleaning agents to clean acid, alkali cleaning agent wipe, film layer is not damaged;

8, impact resistance of 3mm thickness glass impact performance is equivalent to 6mm acrylic;

9, keep the Angle of view general acrylic in the installation, the Angle of view will become smaller; When AR glass is installed, the Angle of view will not become smaller.
