Nauticam optical-glass dome ports are finely ground to the highest standard of precision and represent the state of the art in both manufacturing and optical technology. Different size ports are available to support a wide variety of lenses and housing types. Port extensions or adapters may be necessary for some ports and housings. This optical-glass wide-angle port has a diameter of 250mm and is part of the N120 port system.

The 18807 (N120) and 16405 (N200) dome ports, with a shallower 40m depth rating continue to be available in our product line and are still recommended for diving within recreational limits. This version is a more “heavy duty” variant designed to support deeper depths with a limit of 100m. The original designs are also lighter weight and less expensive.
