Meller Optics, Inc. has unveiled its new custom-made sapphire windows for surveillance unmanned underwater vehicles (UUVs) and autonomous underwater vehicles (AUVs).

Robust Sapphire Windows Unveiled for Unmanned Underwater Vehicles

Designed to withstand high-speed particulates and high pressure, the sapphire windows are custom manufactured to precise OEM specifications. 

The new windows can include stepped edges, elliptical edge shaping, holes, slots, and wedges for mounting, and feature a smooth flat surface that resists algae growth.

Meller Sapphire Windows feature Mohs 9 hardness (second only to diamond) and can withstand fast moving particles, sand, and deep water pressure to 10,000 psi, depending upon application. 

Providing outboard surface protection for imaging sensors and subsea vision systems, Meller Sapphire Windows can be made in sizes from 0.25″ to 10″ O.D. with varying wall thicknesses and treatments. 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.

Meller Sapphire Windows for AUV & UUV applications are priced according to configuration and quantity.
