Sapphire offers excellent light transmission in the 0.20 to 5.50μm wavelength range, making it ideal for laser and infrared optical applications. Our products are widely utilized in endoscopes, watch glass, optical lenses, surface acoustic wave filters, military infrared windows, optical filters, observation windows for high/low temperatures, and cosmetic instrument windows, among others. Additionally, we provide services for anti-reflection, high-reflective, dielectric, filter, and metallized films.
Sapphire windows are primarily available in four types: circular, oval, oblique circular, and step windows.
