Sea & Sea Universal Dome Port 210 A/R II

Sea & Sea Universal Dome Port 210 A/R

Introducing the revolutionary new "Universal Dome Port 210". This dome port is made from a newly developed material called PLANEXT®, providing unprecendented performance and versatitility. 

Optical performance

Compared with conventional acrylic material or optical glass, PLANEXⓇ produces superior or better optical performance. (See chart)

With high-precision injection molding methods, SEA&SEA has succeeded in producing a dome that has the same curvature as a concave meniscus lens*. The 210 AR dome’s optical distortion is as small as that of optical glass lenses. When used with an internal correction lens, the best image quality required for high-end cameras can be obtained. The dome is treated with a multi AR coating to prevent internal reflection from occurring (see comparison).

Strength Performance

Because of PLANEXT’s exceptional cohesive strength and due to a newly designed base, the dome ports’ depth rating is now 100m/330ft.

Compatibility 

Compatible with all the wide-angle conversion lenses on the system charts posted on SEA&SEA’s website. The UDP 120 AR II is designed with a housing bayonet mount that is easily replaceable. An additional Nauticam bayonet compatible is also included for user versatility.

Dome Replacement 

The UDP 210 AR II has been designed with usability in mind. The dome can be quickly and easily replaced by the user in any environment, therefore even if due to an unfortunate incident domes can be replaced on the spot.

For compatibility please refer to Sea & Sea's system port chart.

* Lens having convex curvature on one side and concave curvature on the other side.
