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.
Sapphire is the second hardest crystal next to diamonds. Due to its structural strength, sapphire windows can be made much thinner than other common windows, with better transmittance performance.
