Dome Port Lens for Subsea Camera Photogrphy

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.  

Dome Port Lenses  are ideal for split-level and underwater use – While dome ports will not take anything away from your work above water, their impact or difference above the surface is irrelevant. Domes are ideal for split-level and underwater work.

Domes are typically found in single-use defense applications and submersible vehicles for deep ocean exploration, sapphire glass dome has advantage from its material property. 

Why use Dome ports for Underwater Photography? 

Domes help correct aberrations that occur when light travels thru water as opposed to air. Domes can deliver better results compared to flat ports, and also make it easier or possible some results that flat ports would not capture.
Size matters – Bigger domes are better than smaller domes, for a number of reasons. The tradeoffs are; heavier, bulkier, pricier than smaller domes.
Glass is optically superior – Glass domes are optically superior to plastic or acrylic, and they do not scratch as easily.
