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. Wloptical can provide anti-reflection film, high-reflective film, dielectric film, filter film and metallized film services.

Sapphire Balls & Hemispherical balls are largely used in precision measurement, micro-fluid spool, flow-meter ball valve, optical fiber communications and optical lens because of its characteristics of anti-corrosion, wearable and fine transmission.

Extremely hard, strong and wear resistant
Excellent thermal conductivity/heat resistance
Exceptionalchemical stability
Excellent transmission bandwidths (UV to IR)
Blank substrates, AR-coated pieces, and precision windows are available
