Why choose Single Crystal Sapphire products?
Single crystal sapphire possesses excellent optical, physical and
chemical properties. It is the hardest oxide crystals, and remains
high strength and chemical resistance at high temperatures. It also
features a wide transmission wavelength range, great electrical
insulation, and good thermal conductivity at low
temperatures.
