Default Zinnia: UV Induced Visible Fluorescence using Nichia UV LEDs

Well, some people wonder what could be done with Nichia based flashlights / torches which use the single dice NCSU033A (older) or NCSU033B (newer) chips.

Well, here is my example without much ado...

White Zinnia in visible light:


White Zinnia in UV induced visible fluorescence, variant 1:


White Zinnia in UV induced visible fluorescence, variant 2:


I hope that serves as an example what could be done with those UV flashlights, but of course those are useful for many different applications such as stimulating visible fluorescence, reflected UV photography, forensic, dermatological and dental examinations and photographic recording, curing of UV glue / bonding, as well as leakage detection etc.

... or simply just pretty pictures ;-)
