Product Description
Ball lenses are great tools for improving signal coupling between fibers, emitters, and detectors. Polished sapphire and ruby balls are used with D = 0.3–6.35 mm ± 2.54 m m and a sphericity to within 0.64mm.
CD disks are fabricated of polycarbonate. In the near future sapphire disks will be developed for long-term storage of significant data.
