Fluorescence Excitation Filters
NIGHTSEA’s fluorescence excitation filters turn your electronic flash into a source of intense blue light for taking fluorescence photographs. The key element is our custom made interference filter that transmits just the blue light you need for underwater fluorescence photography. They are used in conjunction with a barrier filter in front of your camera to record the vibrant images you see in the photo galleries.
You can even take fluorescence photographs in the daytime – with a short shutter speed you can underexpose the ambient light without affecting the fluorescence image.
NIGHTSEA offers a variety of excitation filters for underwater use:
- EX-Z330 – specially designed to mount on the Inon Z-330 strobe. The filter has a bayonet mount to the front of the flash, the same way that the diffuser supplied with the flash attaches.
