Ikelite 3.6" Yellow Barrier Filter for Underwater Lens Ports

Discover a new realm of underwater photography with the 3.6" Yellow Barrier Filter for Underwater Lens Ports by Ikelite. This vibrant and luminous filter is designed to transform your regular diving lights into a fluorescence setup, opening up a world of radiant colors beneath the waves, without the need for expensive specialty lights or guided dives.Experience the magic of fluorescence underwater, a phenomenon where corals and marine animals emit a glow in shades of greens, blues, and reds. This is achieved by using a light with an "excitation filter" and a "barrier filter" on your camera system and mask. Interestingly, you may find two similar corals, one that fluoresces and one that doesn't, adding an element of surprise to your underwater exploration.Fluorescence, in simple terms, is the glow you see in glow sticks, jellyfish, and forensics. It's technically the photon emitted as an electron relaxes from its excited state to its ground state. Many organisms and materials, both above and below water, exhibit fluorescence, often when exposed to a specific wavelength of light.This bright and radiant filter is not just for night diving. You can capture stunning fluorescence photography during the day by experimenting with a powerful, filtered light source and under-exposing the ambient light. Designed for compatibility, this filter can be used with the Ikelite W20 and W30 lenses, as well as any 3.6-inch diameter housing lens port. Dive into your favorite spots in a different light with the 3.6" Yellow Barrier Filter for Underwater Lens Ports and uncover the hidden beauty of the underwater world.
