Sapphire Domes

Meller Optics’ tough high-precision sapphire domes can be provided with diameters of up to 100 mm and included viewing angles of up to 180 degrees. Manufactured on a highly repeatable 5-axis spherical machining center, they feature wall thickness variation of less than 25 microns and other dimensional tolerances of down to +/-10 microns.

Domes can also be manufactured from other materials upon request, including quartz, optical glass, silicon, zinc sulfide, germanium, Spinel and Alon.
