These custom sapphire optics are precision-manufactured in a wide range of configurations with holes, slots, wedges, stepped edges, special coatings, and other characteristics. They feature a Mohs hardness of 9, which is second only to diamond in hardness. They are chemically inert and can be fabricated to precise specifications as lenses, windows, domes, prisms, tubes, rods, and balls, and can be supplied ready for original equipment manufacturer (OEM) assembly. They are available as plano-convex and -concave lenses and windows from 0.5-in. to 6-in. dia., with flatness to 1/10th wave, parallelism to 2 arc-sec, and surface finishes to <0.5 nm. They transmit up to 85% when uncoated, and over 99% when enhanced with a coating, depending upon thickness. The balls come in sizes from 0.005-in. to 0.5-in. dia., with 0.000025-in. per ball sphericity.
