Sapphire
(Al2O3) is a single crystal alumina as opposed to alumina substrates
which are multi crystalline. Sapphire comes from the Persian safir
which means “beloved of Saturn” While sapphire has many desirable
optoelectronic applications, it is not beloved of engineers who
have to machine it because of its hardness. Precision Surface
Technology has developed techniques to machine sapphire and our
engineers would like to discuss your requirements.
