Sapphire Optics
Sapphire Setp Windows for aerospace, medical, and industrial applications
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 windows mainly contain four types: circular windows, oval windows, oblique circular windows and step windows.
