Sapphire Ball Lens and Hemisphere Lens
Balls & balls measuring head jewels are made of synthetic sapphire/ruby. Our most products are at 10 Grade, for some size, we also can reach Grade 5.They are largely used in heavily corrosive environment and optical fiber communication because of its anticorrosion, wearable and fine transmission characteristics. Balls measuring head jewels are used as insulated measure head on precise instruments.

Sapphire Rod
|
Sapphire rods are made of sapphire/ruby, they are widely applied to medicine, accurate machine, accurate measure and inspection and laser technology. They also contribute a lot in the anticorrosion, wearable and high heat conduction environments.
Rods are available with diameters or ends both highly polished. Rods with radius and total or partial flats and angles are available. The Czochralski ruby used in the manufacture of our laser rods is noted for its ultra-high purity - free from inclusions, clouds, bubbles, lineage or axis misorientations. Typical Applications: pumps, light pipes, spacers,insulators,sapphire piston for HPLC system.Main types:
