[FL] Another Bouquet: Gerber Daisy, Hyacinth, Roses,...

Here a UV induced visible fluorescence shot of another flower bouquet using Nichia 365nm UV LED and a 400-700nm UV/IR Cut filter.

and here for comparison the white light (5600K LED) shot

closer to see more details...

Well and here as another comparison, what happens when a Xenon flash with UV filter is used to stimulate fluorescence.

UV Xenon flash, but that leads to IR + red contamination as may be seen here:

and here now using a BG filter to compensate for that

but in overall comparison, the Nichia UV LED wins hands down IMHO!

Stay tuned, more will follow on that fascinating subject...

More info on this very interesting field may be found on my site
