170mm Fisheye Dome Port (Nauticam N120)

Nauticam's optical glass dome ports are finely ground to the highest precision and represent the state of the art in manufacturing and optical technology. This fisheye and wide angle optical glass dome port is 230mm in diameter and is part of the N120 port system. The internal port opening of this port is enlarged for larger diameter lenses such as Canon EF 11-24mm f/4 USM. Port extensions or adapters may be required for some ports and housings.

DP-230 230mm Fisheye Dome Port In keeping with the Zen Underwater tradition of excellence, we are proud to offer our flagship dome port. The DP-230 port is the long awaited solution for photographers using rectilinear wide angle lenses like the Canon 16-35mm f/2.8 L II, Canon 16-35mm f/4  L, Canon 17-40mm f/4 L, and the Nikon 16-35 f/4 VR.  For exceptional image quality from a full frame camera, the DP-230 is the port you’ve been waiting for.  BK7 Optical Glass Dome The DP-230 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.  This coating yields an amazing 99.7%+ transmissive value for true distortion free images. Large Radius Assures a thin water line for over/under shooting, and the optically coated glass surface minimizes water beading. Aluminum Shades Designed to offer a lifetime of service and extend far enough to protect the dome when placed face down.

DP-170 170mm Fisheye Dome Port Die Größe von 170 mm ist reisefreundlich und bewahrt die Zen-Tradition für die besten optischen Ports auf dem Markt. Dieser mehrfach vergütete optische Glas-Dome-Port bietet optische Reinheit, frei von chromatischer Aberration, Streulicht und Verzerrung, was zu atemberaubenden fotografischen Ergebnissen führt. BK7 Optical Glass Dome Das DP-230 besteht aus handgefertigten Materialien mit einer optisch beschichteten BK7-Glaskuppel als Herzstück. Die Oberfläche des Dome-Elements ist mit einer Magnesiumfluorid-Breitband-Antireflexionsbeschichtung beschichtet, um interne Reflexionen von Kameraobjektiven, Beschriftungen auf Kameras usw. zu minimieren, die bei hellem Umgebungslicht ein Problem darstellen können.  Diese Beschichtung ergibt einen erstaunlichen Transmissionswert von über 99,7 % für wirklich verzerrungsfreie Bilder.  Aluminium-Streulichtblenden Sie sind so konzipiert, dass sie ein Leben lang halten und weit genug reichen, um die Kuppel zu schützen, wenn sie mit der Vorderseite nach unten aufgestellt werden.
