Product Description

_{Production Description}

A dome port is a concentric lens that adds an optical element to the camera lens. When the curvature of the dome's inside radius center is situated as close to the nodal point of the lens as possible, the dome port greatly decreases refraction, radial distortion, axial and chromatic aberrations.When using a dome port, all light rays pass through unrefracted, allowing the "in-air" lens to maintain its angle of view. A "virtual image" is formed optically just inches in front of the lens. When using a dome port to photograph a subject underwater, the lens must be focused on the "virtual picture," not the subject itself.
