Sapphire Ball/ Optical parts

Sapphire Spheres, Ruby Ball, Ceramic Balls can be made with drilled holes, ground into hemispherical lenses, drum ball lenses and given an AR coating to minimize reflection for optical applications.

Sapphire is a hard crystal, widely used in watches and mobile phones, beauty equipment, lasers, LEDs, etc.

Sapphire balls can be drilled and used as precision jeweled bearing rollers for low friction and long wear applications. They can also be implemented in high heat applications; their melting point is 2,000 degrees centigrade yet oxidation of the material isn’t a problem. Sapphire also offers good temperature and optical qualities, as well as superior stability.

Ruby balls are currently used in chemical pump check valves, wind indicators, probe and test measurement tips, medical check valves, ball point pens, master ball gauging sets, ball plug gauges, sapphire fiber optic lens systems, tracer tips, gyroscopic wear points and precision metering valve assemblies.
