New Sapphire and Ruby Balls Feature a Mohr 9 Hardness

The Sapphire and Ruby Balls from Meller Optics are available in 42 in. and metric sizes from 0.1 mm to 0.5 in. diameter. The units have surface finishes of 0.008 to 0.010 micron Ra and 0.2 coefficient-of-friction. The balls feature a refractive index of 1.76 microns at 20°C, and 2,000°C melting point. They are suitable for applications such as ball check valves, chromatography pistons and...
