Meller optical domes are fabricated from sapphire, quartz, glass, silicon and germanium in sizes up to 100mm diameter with included angles to 160 degrees and dimensional tolerances to +/-10 microns. Manufactured on a highly repeatable 5-axis spherical machining center, they exhibit less than 25 microns wall thickness variation.
Featuring surface accuracy to less than 1 fringe measured at 633nm and finishes to 20-10 scratch-dig per MIL-PRF-13830, Meller optical domes are well suited for a wide variety of applications including high speed missile domes, viewports, and other front surface optics requirements.
Optical Domes are priced according to material, size, part, geometry and quantity.
