Sapphire Windows
Worldhawk is a provider of sapphire products for various industrial applications, such as Optoelectronics, Industrial equipment , Optical applications, Medical applications, Education & Research, Aerospace applications, Military applications and Watch industry etc.. Sapphire (Al2O3) is characterized by high optical transparency, wear, heat, chemical resistance, high heat conduction and unique dielectric characteristics. Such combination of properties makes it an indispensable material for making highly integral microcircuits, input windows of semiconductor and electrical vacuum devices, technological lasers, optical devices operating under extreme conditions. We offer high volume precision sapphire products, including sapphire wafers, windows, prisms, lenses, substrates, watch glasses and special product according to customer requirement. All products are generated using the latest technology to maximize quality and transmittance. For detail, please click here.
