Port Sea&Sea Dome DX 200 mm Glass

200 mm in diameter. Versatile optical dome port, 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 crystal glass.

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