Underwater Imaging

Color Purity of LEDs

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.

Recent Advances in Deep Sea LEDs for the Offshore Industry

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.

Displacing Darkness: Lights in the Deep Sea

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.

Technical Resources

Subsea High-Definition Video Systems

A technical discussion of the challenges and solutions for High Definition (HD) video systems in subsea applications contrasted against traditional analog technology.

Diode Lasers in Underwater Applications

Diode lasers are particularly well suited to marine applications because of their insensitivity to vibration, long life, compact size, wide input voltage, and instant restrike.

Underwater Light Reflector Design

Two of the most important performance parameters for underwater lights are beam control and beam angle, both of which are primarily functions of reflector design rather than lamp type.

Optimal Lighting Geometry for Underwater Lights and Cameras

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.

The Future of Subsea Imaging is a Vision of Collaboration

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.

DVS-300 Invades Normandy

Our diver video system, DVS-300, assisted in creating the largest and most precise archaeological map of the five invaded beaches in Normandy to commemorate the 70th anniversary of D-Day.

New Discoveries in Lake Baikal by the MIR Submersibles

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.

The Edison Towers

Our SeaBatteries and HMI Lights were used to illuminate the Titanic for a live video feed to two cruise ships that were part of a 1996 expedition.
