Sea&Sea Announces Two 210mm Universal Dome Ports
By Ian Bongso-Seldrup, August 31, 2021 @ 03:00 AM (EST)

Sea&Sea has announced two new 210mm (8-inch) universal dome ports made from optical grade acrylic (PMMA).

The UDP 210 ARII replaces the UDP 210 AR, released in February last year, and has a lot in common with its predecessor, including the aluminum alloy body material, ABS hood, and 330 feet (100m) depth rating. The main difference is that the new version uses the “highest optical grade” PMMA material with “a refractive index close to glass allowing a high degree of light transmission.” The dome is treated with a 7-layer antireflective coating—hence the “AR” in the model number.

The UDP 210 is very similar to the UDP 210 ARII, but doesn’t feature the antireflective coating. According to Sea&Sea, the dome port replaces the 10-inch Fisheye Dome 240 and is similarly compatible with the corresponding lenses featured in the company’s port system chart.

Contact your local Sea&Sea dealer for pricing and availability.

PRODUCT INFORMATION

Universal Dome Port 210 ARâ…¡

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 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.
 


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.

Specifications

  • Size: Maximum diameter 250 mm x depth 104 mm. Dome Diameter 210mm
  • Weight: 1,310g (2.88 lbs)
  • Depth Rating: 100 M (328 ft)
  • Body Material: Corrosion-resistant aluminum alloy (anodized, internal anti-reflection coating)
  • Hood: ABS resin
  • Dome Material: Special optical PMMA

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 now 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.
