One thought though....what are you going to use for a barrier filter so you only see the fluorescence and not the incident blue light ?
Seems like whether you're looking for glasses to protect from UV, or buying the commercial alternatives from Nightsea or Glowdive, you get yellow plastic. (acrylic? plexiglass?) I bought a couple of Rosco gel sheets to use as barrier filters above water, just to get a sense of it when using blacklights or filtered strobe as UV source... I can post some photos I took with the gel in front of the lens, but I am not sure how to DIY the barrier sheets. Maybe ordinary plexiglass is fine? The gel sheets come with data on the pass bandwidth, so I thought I could narrow down color that way, then get plastic sheets. OR... if the gel sheets were particularly good, I could sandwich between two pieces of clear plastic and seal all the way around with silicon, and make some to hold in front of (or clamp on) masks, ports, etc. Look at the amazing gel options:
Here's another thing I didn't mention yet. I bought a couple of Rosco dichroic glass filters that only let UV pass through (aka Woods Glass). The small rectangular one is almost a perfect fit for a Nikon SB-900, so I attached it and tried some shots. I think the pass bandwidth is low and very narrow, so not much of the light from the flash actually gets through. If the results had been more promising I would have adapted a homebrew snoot to put the 2" circular one in front of my Ikelite strobe. Instead I think I'm better off with the tried and proven royal blue filters I see others using.
Maybe Rosco 80 is the right part of the spectrum to put in front of the strobes...
I'm sure I'm plowing through ground others have covered, and I'd love to hear from them. If I lived close to some salt water I could do some trial-and-error, but...
