Acrylic Dome Lens with Flange

Dome lenses are hemispherical windows that provide a protective boundary while allowing a clear view between the two environments.The Dome lens helps correct the aberrations that occur when light passes through water instead of air. A dome lens can give better results than an optical window, and also makes it easier or possible to obtain some results that an optical window cannot capture.

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.
