Dome View Ports – Best Performance Under Pressure

November 5th, 2018 | Technical ResourcesUnderwater Imaging

Creating crisp, high-resolution imaging for subsea applications requires overcoming a unique set of challenges. Every piece of equipment must not only withstand the high pressure far below the surface, but also account for the way light interacts with water.

Understanding the Basics of Underwater Lighting

Understanding the Basics of Underwater Lighting

May 1st, 2013 | Technical ResourcesUnderwater Imaging

In subsea photographic and video imaging applications, one of the challenges that system designers, integrators, and operators face is bringing along all of the light they will need for tasks below depths of about 150 to 250 m. At these depths, an understanding of how light propagates through water helps designers and users balance mission requirements against the real-world constraints of underwater lighting while helping them make informed lighting choices.

Diode Lasers in Underwater Applications

Diode Lasers in Underwater Applications

June 1st, 2010 | Technical ResourcesUnderwater Lasers

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.
Advanced Underwater LED Power Supply and Light Control

Advanced Underwater LED Power Supply and Light Control

May 20th, 2010 | Press ReleasesTechnical ResourcesUnderwater Imaging

While great attention is given to LED solid state devices during their rapid evolution, they are just one component in a larger electronic circuit. LEDs are tiny, fragile devices that will be easily damaged if allowed to overheat or if exposed to excessive voltage or currents. These devices need an external electronic circuit, commonly called a driver, to safely control the power applied to them. This article will look at the driver circuitry behind the light emitters.
Color Purity of LEDs

Color Purity of LEDs

December 14th, 2009 | Technical ResourcesUnderwater Imaging

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.
Underwater Light Reflector Design

Underwater Light Reflector Design

November 1st, 2008 | Technical ResourcesUnderwater Imaging

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

Optimal Lighting Geometry for Underwater Lights and Cameras

September 1st, 2008 | Technical ResourcesUnderwater Imaging

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.
