The DP-100 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.
One of our newest additions is the DP-100-CR model, which offers a removable shade to utilize the Canon 8-15mm FE in its full range. This is currently available for Nauticam, Sea & Sea, and Aquatica.
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.
