ultrathin sapphire glass wafer ,4inch 0.5mm C-axis sapphire wafer for epi-ready,sapphire thick glass lens for covering,sapphire optical windows,4inch 0.3mm thickness sapphire wafer,

Scientists have developed a new method for creating sapphire wafers with high optical quality for use in microfluidic devices. A 12-inch sapphire wafer of optical grade is made of a material with a large diameter and high thickness. This material is able to hold up to extreme pressures and temperatures, while also being very strong. The new method is based on a combination of two technologies: chemical vapor deposition and thermal evaporation.

Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm.Sapphire , so making them ideal materials for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. And sapphire also is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance.
