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 dome produces extremely high-contrast images.
Depth Rating: 100m
Construction: POM resin, BK7 crystal glass dome and corrosion-resistant aluminium alloy shade
Included Accessories: Instruction Manual, Port Cover, Port Case
