No noticeable patterns, as expected though.

visible light shot:
UV shot (using Baader U-filter and Xenon flash):
Butterfly vision shot (using my XBV2 filter):
UV induced visible flourescence shot (using Baader UV/IR Cut filter and Nichia 365nm UV light):
As boring as it might look like, this now is quite interesting (to me) as it shows UV induced IR fluorescence. Lights were all Nichia UV LED sources I could get hold of (to make sure not a bit of IR would be present), a B+W 092 cut filter (>65nm) in front of the lens and 30sec exposure in total darkness:
With the naked (but UV protected!!) eye quite a bit deep red fluorescence gets visible, but hard to ban that on a photo....
Same experiment but using a dark orange filter and same UV lighting setup in darkness (Nichia 4x 365nm LED using a front attached Baader U-filter to block any visible light!):
I have now found a reliable method to professionally infinity convert Noflexar 35mm lenses to Nikon mount - ask me if you need one!
Stay tuned, more will follow on that fascinating subject...
