• Versatile optical dome port.
• Compatible with various fisheye and wide-angle lenses.
• Boasts the best image quality, including peripheral image quality.
• Suitable for half-underwater-half-topside images.
• Peripheral image quality will be even better when used with an Internal Correction Lens.

Features:

• Uses high quality BK7 crystal glass.
• 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.
