Sea&Sea Dome Optical Glass II - 230mm

Features

・ Uses high quality BK7 glass.
・ Two different anti-reflection coatings are employed to optimize image quality, one for the exterior and one for the interior of the optical domes. A multilayer coating is used on the outside of the domes and the inside of the domes 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.
