Sea&Sea Announces 210mm Dome Ports

Sea&Sea has announced two new 210mm dome ports. They are both constructed of PMMA acrylic and are supplied with bayonet fittings for both Sea&Sea and Nauticam housings. One version of the port has a seven-layer anti-reflective coating.

The Universal Dome Port II and Universal Dome Port AR II are shipping now, please consult your local dealer for pricing details.

Universal Dome Port 210 ARⅡ

Product No.30204
By designing a dedicated mold, Sea&Sea has been able to incorporate a meniscus lens design in the UDP dome construction, which reduces the spherical aberration and beam waste.

Therefore, the refractive power changes gradually from the center of the port to the peripheral area, allowing the different radii of curvature to create a clearer focus at the peripheral areas compared to that of conventional ports.

By using the highest optical grade PMMA material, the UDP 210 ARII has a refractive index close to glass allowing a high degree of light transmission. In addition, Sea&Sea has achieved a 7-layer Anti Reflective (AR) coating to reduce internal reflection and the effects of decreased contrast.

Comparison of lens reflection

The port has also been designed with usability in mind, as the dome can be replaced quickly and easily on the spot in any environment. In addition, the dome is also supplied with an additional bayonet mount, that can be simply attached with the six existing screws to provide compatibility with all 3rd party Nauticam housings.

Compatible with all lenses listed on the port system chart when the port combination follows the UDP 210 AR.

Universal Dome Port 210

Product No.30205

By designing a dedicated mold, Sea&Sea has been able to incorporate a meniscus lens design in the dome construction, which reduces the spherical aberration and beam.
Therefore, the refractive power changes gradually from the center of the port to the peripheral area, allowing the different radii of curvature to create a clearer focus at the peripheral areas compared to that of conventional ports. The new UDP 210 will not replace the discontinued Fisheye dome 240 #30116

By using the highest optical grade PMMA material, the UDP 210 has a refractive index close to glass allowing high degree of light transmission.

Compatible with all lenses listed on the port system chart, when the port combination conforms to the Fisheye Dome 240.
