・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.
