Overview & Features
Ikelite 6141.19 yellow barrier filter for diving mask. The yellow barrier filter is placed on the diving mask, it blocks the bluish light reflected by the subject to be photographed, allowing only the emitted fluorescence to pass through. It is the filter used to capture green fluorescence, very common in coral reefs.
Looking for something different? Tired of night diving? Fluorescence
will give you a whole new perspective on the world beneath the waves.
With our line of excitation and barrier filters, you can convert your
existing lights into a fluorescence set-up. No need to purchase
expensive specialty lights or guided dives. Be the explorer!
ABOUT FLUORESCENCE
To see this underwater, you'll need a light with an "excitation
filter" attached and "barrier filters" attached to both your mask and
camera system. What you'll generally see is a glow emitted from a
variety of corals and animals, mostly in greens, blues, and reds. You
may find two of the same type of corals—one which fluoresces, and one
which doesn't. Dive your favorite spots in a different light and see
what you've been missing!
Fluorescence is technically the photon
emitted as an electron relaxes from its excited state to its ground
state. In layman's terms, it's the glowing you are familiar with in glow
sticks, jellyfish, and forensics. A variety of organisms and materials
above and below water exhibit fluorescence—often with the introduction
of a particular wavelength of light.
Fluorescence photography may
be captured during the day by experimenting with using a very powerful,
filtered light source and under-exposing the ambient light.
