Optical Glass Dome Lens Optics

Dome is composed of two parallel optical surfaces. Among optics domes are unique because, unlike any other optical components, the key attribute of the dome is to have no optical effect. 

Generally a dome is often exposed to the environment. Accordingly, domes made from hard ceramic materials are preferred due to their ability to withstand wind and rain erosion. 

Domes are typically found in single-use defense applications and submersible vehicles for deep ocean exploration.
