Sapphire Ball Lens & Hemispherical Lens
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 Balls & drilled 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.
