Fluorescent Night Diving In Lembeh Strait

Fluorescent Night Dive

There is nothing quite as exciting as a fluorescent night dive. And sure those two little wordsnight dive可能会给某些人提供Hibigeebies，但要抓住自己的紫外线火炬，并在黄色的过滤器上绑带，您将恳求指南永不结束潜水。
The Lembeh Strait is famous formuck diving还有大量的疯狂小动物，但您还可以发现许多罕见和不寻常的珊瑚在天黑后生成。

The Science Behind Fluorescent Corals

珊瑚s get their colors in two ways. Corals have photosynthetic marine algae living inside their cells which convert sunlight into energy for the coral. The brownish green color you see in corals under normal daylights is from these algae called zooxanthellae. When corals are bleached, they turn white because they expel the zooxanthellae.
但是后来有蓝色，绿色，紫色和红色来自一个家庭Nobel prize-winningfluorescent proteins. Without使您对科学的压倒, the short answer is there is protein pigment in the tissue of corals which absorbs light in one color, and re-emits the light in a different color. These pigments look different under white light, daylight, and blue light.

On the atomic level, an organism’s fluorescent molecules absorb the photons – tiny parcels of light – given off by the external source. When they collide with the fluorescent molecule, the photons “excite” the molecule by bumping its electrons up to a higher energy state. –Luminescence Lab

But the fluorescent magic happens when you shine a long wavelength light source, ultraviolet or blue light, at the coral. Under long wavelength of light, the protein re-emits a fluorescent pigment as biofluorescence that glows a bright neon color.
在水下，如果您只是使用紫外线，您会看到珊瑚色的蓝色，粉红色和紫色的迷幻阴影。而且，如果您在面膜或相机上添加黄色过滤器，则颜色将为绿色，黄色和红色。这种颜色在正常的光条件下是看不见的，只有在使用较短的光波长（例如蓝色或紫外线）激发颜料时，您才能看到它。
The image below shows the difference between corals under UV light to the naked eye and UV to the camera with a yellow filter. To learn more about bioluminescence and fluorescence we recommend visiting theLuminescence Labwebsite.

Fluoro Gear

要获得氟效果，您将需要紫外线。而且，如果您害怕夜间潜水，不必担心，尽管效果并没有那么惊人，但您仍然可以看到富罗罗的颜色。如果您只是在没有相机的情况下跳水，不需要黄色的过滤器，只有在您想开始拍照时，此次要配件才派上用场。
The UV light I use is aSola Nightseaby Light and Motion. The NightSea has a super bright 3000mW flood and 1700mW spot beam with three light intensity settings.
This is the third UV light we’ve tested and find the NightSea has the brightest beam and best color rendition. The other UV lights we tried were more on the purple side and had narrow light beams.
I actually carry a UV light with me on every dive, day or night, as the UV brings out colorful neon colors visible to the naked eye. With a UV light during the day you can see blues, pinks, greens, and purples, however, cameras have a difficult time capturing these colors and most photos will end up solid blue.

您可以购买适合相机和面罩的黄色过滤器。XS水肺使Switch Maskwhich allows you to insert a yellow fluoro filter on top of your mask lens.

You can buy a yellow filter that clips onto your light, covers your camera lens, or fits overtop of your goggles, and companies likeXS Scubaeven make a mask with a removable fluoro lens cover.
如果您在到达之前先与潜水中心进行Fluoro潜水检查感兴趣，以查看他们是否提供这种令人毛骨悚然的夜间潜水体验。而且，如果您对这个想法感到非常兴奋，那么我建议您购买自己的Fluoro装备，并且不要没有它！
