Well, some people wonder what could be done with Nichia based NC4U133 (365nm) / NC4U134 (385nm) systems
http://photographyoftheinvisibleworld.blogspot.de/2011/01/nichia-high-power-4-dice-nc4u133.html
my High Power UV LED Radiation System with easily exchangeable radiation heads using the most modern 40W UV LEDs
http://photographyoftheinvisibleworld.blogspot.de/2012/09/high-power-uv-led-radiation-system.html
or the simple and now quite common 365nm Nichia flashlights
http://photographyoftheinvisibleworld.blogspot.de/2012/09/nichia-365nm-flashlight-beam.html
which use the single dice NCSU033A and NCSU033B 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 Wink

Beautiful work, Klaus, I'm partial to the second image. it reminds me of those black felt pictures under
black lights I used to have in the late 60's/early 70's, with of course the usual recreational drugs back
then. Smile
