In March 2022, subsea explorers made a profound discovery at a depth of 3,008 m (9,869 ft) below the surface of the Weddell Sea’s icy Antarctic waters. The Endurance22 Expedition, supported by the Falklands Maritime Heritage Trust, located the wreck of the Endurance, a wooden ship that sank off the coast of Antarctica in 1915 after getting trapped in the pack ice.
The term “Color Purity” often invites inquiries from customers viewing the spectral graphs generated by our integrating sphere. Color Purity was specifically created for LEDs with the 1997 CIE 127 Document and does not apply to any other type of light source, such as HID, HMI, CFL, or incandescent.
Manned vehicles, ROVs, and Saturation Divers are adopting Light Emitting Diodes (LEDs) as powerful and durable light sources. Developments continue to follow the rapid evolution of LEDs for general topside illumination. Our engineers have devised compact ocean optics, both reflectors and lenses. Successful pressure compensation of both LEDs and driver electronics foretell future designs in diver and vehicle lighting.
Our line of underwater lights are used around the world by the most demanding end users in the earth's most extreme environments, including hot water hydrothermal vents, high pressure ocean trenches, radioactive nuclear storage facilities, and biohazardous sewage treatment plants.
Following ideal reflector design, the placement of an underwater light, or "luminaire", relative to the camera will have the greatest affect on image quality, due to "Common Volume Scattering," which can result in backscatter in the present of suspended particles or organisms.
Collaborating on the Future of 4K Subsea Imaging In 2018, scientists and engineers at the Monterey Bay Aquarium Research Institute (MBARI) began researching upgrades to their high-definition camera systems on the 1,800-meter ROV Ventana and the 4,000-meter ROV Doc Ricketts.
The MIRs have provided stable light and camera platforms for the making of well known deep ocean films, including James Cameron’s Titanic, Bismarck, Ghost of the Abyss, IMAX Titanica, Al Giddings’ Treasure of the Deep, and BBC’s Blue Planet.
Pressure testing has a long and storied history and remains one of the most useful tools subsea designers have available. It is a critical part of preparation but can be one of the first steps cut when resources get stretched.
