Blu-ray fluorescence difference based on wavelength

Would a 415 nm diode produce a noticeable weaker fluorescence then a 400-405 nm one? I just bought a higher wavelength GGW and I am curious about this effect.

This would not make any appreciable, practical difference.

From our top florescence expert, himself.
bob808;You really should to do a search for pics. of some of Dave's minerals.

Awesome collection!!
Even the "few extra" ones, he sent me are a great collection.

I can only imagine the "Motherload"
If I only lived a couple thousand miles closer......I'd drive 5-6 hundred miles to see them.


I don't know a lot about florescence, but I have a 20W 380nm.<{not a laser, UV leak detector lamp}
I thought it would light up some of my minerals like a Christmas tree.
(The 20W 380nm will sunburn you with <15 seconds of exposure)
No florescence at all, using minerals that glow very bright with 405nm
It must be near UV that is activating the florescence.

Different minerals react to different UV "ranges." Minerals that react to long wave UV may not react at all or may react differently to short wave UV.

Everyone please be extra careful with short wave UV, the worst DNA damage is from 280 to 285 nm UV and a cancer is not the result we want. It takes only about 1 second to kill 99% of all germs and reproductive capacity of insects with only about 3 watts at 4 inches distance. So that light is truly a Cancer lamp! btw, there is very significant cataract and other eye damage also quite possible with these too! -Glenn

Hey Bob, Where did you get the higher wavelength GGW? 415 would be kind of interesting to see...

I got it from Scopeguy! I don't know if it's 415 or so, but being a higher wavelength and considering the fact that you can tell visually I'd say it's about 410 at least. The downside with them thou seems to be the lower power but not much. Since nowadays there are 12x diodes that burn a lot I thought that I might get a nice visual beam instead. Atm I got on the way a pocket mini kit from Jayrob, this diode from Scopeguy and some rechargeables from AW. When everything is here and I finish the build I'll post some pics with the beam :) Waiting is the hardest part :/
