Knight Optical offer a range of Stock N-BK7 Dome Windows, for use with Underwater Lighting. A dome is an optical window composed of two parallel curved surfaces. Domes are commonly used in defence applications and often in extreme environments such as Submersible ROV’s. The shape of the window creates a naturally strong shape that gets tougher under pressure. Using a curved dome optical surface allows for an increased beam angle, therefore allowing a greater area to be lit from one light source. For visible applications, N-BK7 with its high optical quality and uniform transmission and low absorption in the visible spectrum makes it an ideal material for underwater lighting. A tough and cost effective solution which allows for good transmission of the light source in the underwater environment will both protect the light source as well as transmitting from 300nm up to 2µm.
