    Sapphire optics, including precision balls, lenses, windows, and front-surface optics capable of withstanding harsh environments, can be custom-fabricated.

    Sapphire optics, including precision balls, lenses, windows, and front-surface optics capable of withstanding harsh environments, can be custom-fabricated. The optics have 9-Moh surface hardness and thermal stability to 2000°C and can withstand pressures up to 4000 psi, depending on configuration. Balls range from 0.005 to 0.5 in. in diameter, and concave and convex optics run from 0.5- to 6-in. diameters.
