The DP-200 is constructed from hand crafted materials with an optically coated BK7 glass dome at its core. The surface of the dome element is coated with a magnesium fluoride broadband anti-reflective coating to minimize internal reflections from camera lenses, lettering on cameras, etc. which can be a problem in a bright ambient light situation. The exterior is treated with a proprietary scratch resistant coating to control lens flare. This coating yields an amazing 99.7%+ transmissive value for true distortion free images.
The exclusive Zen Modular Mount mates with the dome assembly via a reliable and rugged bayonet mount, eliminating any possibility of dissimilar metal corrosion. The mount currently support Nauticam N120, Subal Type 4, Sea & Sea, Nexus M5, and Aquatica housings.
The heavy duty aluminum shade is designed to offer a lifetime of service and extends far enough to protect the dome when placed face down.
