UV Excitation Filters

Do you know FluoDiving?

FluoDiving is diving using ultra-violet light or a light with an "excitation filter" attached to get the fluorescent colors of animals or plants in sea and fresh water. To filter the blue light and let only pass the fluorescent colors you must use a yellow filter and you will get spectacular pictures or movies.       

If you would like to see the fluorescent colors in time, we suggest using the equivalent filters for your diving mask. https://www.aditech-uw.com/en/shop/2900-mangrove-filtre-jaune-cf-m-y.html      

The underwater yellow filter can be attached or detached even under water according to the current situation. With a small snap cord, which is included here, the yellow filter can be attached to the housing so it will not get lost.  

Fluorescence is a process that begins with chemical compounds called fluorophores as they absorb light energy from an outside source. Atoms and molecules within the fluorophores then emit their own light at lower energies and wavelengths that correspond to the original light source, making the fluorophores appear to glow. The proteins in many fish, coral, or other underwater life contain fluorophores, creating the opportunity for unusual or unique images. Since blue or UV wavelengths with their relatively high energy levels can yield the most intense fluorophore reactions, blue or UV light sources are considered ideal for producing the most colorful and easy-to-photograph fluorophore effects.

However, because the light from a blue or UV lamp used to excite the atoms and molecules within the fluorophores is more intense than the lower-energy fluorophore glow, such lamps can end up obscuring that glow from fish or corals while trying to photograph them. The Mangrove Underwater Barrier Filter makes it possible to capture images of fluorescing underwater life by blocking the light from a blue or UV excitation light being used to provide the energy needed to initiate the fluorophore reaction while allowing the resulting glow into your lens and camera.
