Why Choose sapphire crystal?

1. Thinner and Stronger than Standard Glass Windows
2. Transmits Wavelengths Ranging From UV to Mid-Infrared
3. Features Extreme Surface Hardness and Chemical Resistance
Sapphire is the general name for corundum stones of all colors except the red ruby. Its main ingredient is alumina (AI2O3). Sapphire glass is a synthetic sapphire,Gem-grade sapphires can be easily and cheaply produced in the laboratory and have the same chemical composition and physical properties as natural gems.
Sapphire crystal is more reflective than mineral crystal due to its higher index of refraction. (1,8 compared to 1,47). Applying one or more layers of AR (anti-reflective) coating will limit this reflection to a very low level. Very often, lines and marks on the top surface of a sapphire crystal are mistaken for scratches but are actually the scratched AR coating, or just AR coating wearing off after time. An AR coating on the inside of the crystal provides a good AR performance while avoiding this problem. If you do scratch a sapphire crystal, then it cannot be polished away and will need to be replaced.
