Funny thought about bluray...

[pseudolobster]

I had a funny thought about bluray the other day, I was looking for some florescent airsoft pellets scattered around my room, so I've found the easiest way to find them is to turn off the lights and hunt for them using my bluray... When I hit one it lights up my whole room bright orange, and the flash is a bit hard on the eyes...
I've heard people here warn not to do this, since the bright florescence could be damaging to the eyes... Which got me thinking... Florescence can never create any more photons, it's simply reemitting the existing light a higher wavelength... So how can the florescence be any worse for your eyes than the bluray itself? Aren't my eyes already being exposed to this brightness of light, just I can't see it?

In that case, isn't shining your bluray on florescent surfaces actually safer than shining it on non-florescent ones, since the eye will contract the iris when the wavelength is in the visible spectrum?

no matter how you wanna think aobut it. It's a lot of light hitting your eye. Now since it's more visible in the higher wavelength just means your eyes can close the pupils more. That's it.

Wow, great question. Makes you think. I don't know the answer but I'll read what comes next..... :bumpit:

The fluorescence would not be collimated and probably not coherent, so I highly doubt that it will damage your eyes.

Agreed, but don't understand.




Seems like a nice way to find em.. but would it not be easier to just send a roomba round and pick em outa de dust bin, thats what I do when I lose my laser pieces

Can i give you a suggestion ?

Defocus your blue-ray laser, or just put a positive lens in front of it, so that what you get is sorta of blur/UV torch ..... powerfl enough for find your BB, not enough for cause you damage to eyes, large spot for easy illuminate more space than a thin ray (so you can find them more easy), and also the fluorescence is lower, so don't get too much fastidious to your eyes.

Anyway, don't be scared from just fluorescence, it can't cause to your eyes damage, at maximum, if it's really strong, a "post-flash" effect, that disappear in minutes (but must be REALLY strong, for that )
