Ruby Ball With Various Of Diameters For Fiber Optic Communication
Sapphire, which is derived from the Latin Spphins, which means blue; it belongs to the corundum group of minerals in the trigonal crystal system. In the gem world, all colors of gem-grade corundum other than rubies are called sapphires.
The main component of sapphire is alumina (Al2O3). Corundum contains trace elements such as iron (Fe) and titanium (Ti), and presents colors such as blue, sky blue, and light blue, among which the bright sky blue is the best.
Sapphire Ruby ball is made of artificial blue / ruby monocrystalline as a material, it has the advantage of corrosion-resistant, wear-resistant, good light transmission and other characteristics.
In a highly corrosive environment with the use of liquid, gas flow meter ball valve, fiber optic communication and other aspects have been adopted.
Gem blind hole balls made from deep processing of gem balls can be used as insulation measuring heads for metering instruments and precision metering instruments.
Optical ball lens grade up to 3 levels, spherical diameter from 0.4-250mm diameter, spherical diameter tolerance of up to -0.001, mainly used in laser, optical communications, infrared applications, medical imaging, photovoltaic industry and other fields.
