Dome is made from “PLANEXT®”
Made from newly developed material called PLANEXT® and produced by a high-precision injection molding method that provides unprecedented product performance and versatility. PLANEXT® is a morphous bioplastic which also realises carbon neutral properties ideally suited for underwater photography. Compared with conventional acrylic material or optical glass, PLANEXT® produces superior or comparable optical performance. Manufactured with high-precision injection molding, SEA&SEA has succeeded in producing a dome that has the same curvature as a concave meniscus lens.
The UDP 210AR optical distortion is as small as that of optical glass lenses and when used with an internal correction lens, the highest image quality of high-end cameras can be obtained.
Though the dome is made from plastic, it can be treated with stable AR coating. The UDP 210 AR has Anti Reflective coatings to prevent internal reflection.
With PLANEXT’s exceptional cohesive strength (Charpy impact strength) and newly designed base, the UDP 210AR depth rating is now 100m.
Compatible with all the wide-angle lenses on SEA&SEA’s system chart (SEA&SEA’s website as of 2019).
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.
