just curious if anyone has aimed there bluray at a thermal couple to measure the heat generated? Wow that dot gets hot on the finger!! Maybe I'll try it... Hmmm maybe a mw=aprox temp chart would be cool?

I thought I had it at the focus point, but I was using my breath to visualize the beam while focusing it. Not too accurate. Oh well. I'll figure this out...

Yea , I noticed that you have to have a pretty dark skin tone to be burned by a red laser.Blu-ray on the other hand burns white paper, so it will burn white skin pretty well too.It also gives you cancer.laserwanabe said:I was thinking, is it possible to pulse a laser at a rate at which the temperature would be hot enough to kill germs or a disease but leave regular tissue untouched.
I tried using my dx200 on this ginger kids arm, but it didn't do anything except make his arm glow red.( the light dissipated in his arm to quickly)
I would like to know how much heat is produced when properly focused on say black paper.

We don't really have the resources to research this 405nm wave length.
