Sapphire offers excellent light transmission within the 0.20 ~ 5.50μm wavelength range, making it an ideal choice for laser and infrared optical applications. Our products find wide usage in various fields, including endoscopes, watch glass, optical lenses, surface acoustic wave filters, military infrared windows, optical filters, high/low temperature observation windows, and cosmetic instrument windows. We provide a range of services, including anti-reflection, high-reflective, dielectric, filter, and metallized film coatings.
Sapphire optical lenses are commonly employed to control the direction and accuracy of light transmission. With its superior transmittance, sapphire lenses offer longer lifespan and broader spectral adaptability compared to optical glass.
We specialize in processing different types of sapphire convex lenses according to user specifications, such as plano concave lenses, double concave lenses, bi-concave lenses, pcv cylindrical lenses, and bcv cylindrical lenses.
