Versatile optical dome port, 165mm in diameter. Compatible with various fisheye and wide-angle lenses. Peripheral image quality will better when used with an Internal Correction Lens.
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 Dome. A multi-layer coating is used on the dome exterior and the interior of the dome is 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.
