Port Sea&Sea Dome 230 mm Optical II Glass

230 mm in diameter. Boasts the best image quality, including peripheral image quality.

Suitable for half-underwater-half-topside images. Compatible with various fisheye and wide-angle lenses.

Two different anti-reflective coatings are employed to optimize image quality, one for the exterior and the other for the interior of the Optical Domes. A multi-layer coating is used on the dome exteriors and the interior of the domes are coated with silicon-dioxide to effectively suppress flare and ghosting. As a result, the refractive index of each port is reduced to less than 0.01% and the domes produce extremely high-contrast images.
Uses high quality BK7 crystal glass.

Optical Dome Ports come with specially designed and produced dome port cover and port case as standard.
