Zinnia: UV Induced Visible Fluorescence - ultraviolet photography III

So, last few of those Zinnia examples that I have shown before indicating what could be done with Nichia based NC4U133 (365nm) / NC4U134 (385nm) systems and my High Power UV LED Radiation System with easily exchangeable radiation heads for nominal wavelength of 365nm, 385nm, 395nm, 400nm and 405nm using the most modern 40W UV LEDs or the simple and now quite common 365nm Nichia flashlights which use the single dice NCSU033A and NCSU033B chips.

I hope these shots also serve as 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.

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