Meller Optics introduces sapphire optics for high-pressure deepwater applications

March 27, 2023

(WO) – Meller Optics introduced custom fabricated sapphire optics designed for commercial, military, and scientific unmanned underwater vehicles used in deep water applications.

Meller Sapphire Windows and Domes feature Mohs 9 hardness, which is second only to diamond, are capable of withstanding pressures to 10,000 PSI, and provide a smooth, flat surface to help prevent algae growth.  Manufactured to precise user requirements, these robust sapphire optics provide outboard surface protection for vision systems and imaging sensors by withstanding high pressures, saltwater, sand, and other fast-moving particulates.

Available in a wide range of shapes and sizes from 0.25” to 10” O.D. with varying wall thicknesses, Meller Sapphire Windows and Domes can include stepped edges and elliptical edge shaping, holes, slots, and wedges for mounting.  Surface finishes can be held to 10-5 scratch-dig, roughness to less than or equal to 0.3 nm RA, and flatness to 0.5 fringes HeNe.
