Sapphire possesses nice light transmission in 0.20 ~ 5.50μm wave band, is ideal for laser and infrared optical materials. Products widely used in endoscope,watch glass, optical lens, surface acoustic wave filter, military infrared window, optical filter, observation window for high/low temperature and cosmetic instrument windows, etc. We can provide anti-reflection film, high-reflective film, dielectric film, filter film and metallized film services.
Single crystal sapphire exceptional chemical stability and corrosion resistance, 100% gas tightness, high melting temperature of 2030 °C, excellent thermal conductivity and heat resistance. Sapphire tube is ideal material for the protection of thermocouples in corrosive environment. The super reliability of sapphire protection tube significantly improve life expectancy of the thermocouple and reduce interruptions and shutdowns in operation.
AOG SAPPHIRE offers a wide of high quality customized all-surfaces-polished sapphire tubes and fine ground sapphire tubes, such as Capillary tube , Polished sapphire tube, Sapphire plasma tube and Sapphire thermocouple tube.
