Hello all, I hope you are well!
I've just finished building my 15w 450nm beast based on 2x NUBM47-V2's and I noticed something when looking at the dot through my laser glasses, it was visible and quite bright (The glasses are 190-540nm OD6 from survival lasers)
I decided to enclose the laser and glasses in a box with a hole cut behind the glasses, and when the laser is on nothing seems to be passing through. None of my other lasers seem to have this effect, usually I can only just tell if the laser is on or not through these glasses. Even a single NUBM47 @ 7W doesnt seem to have this effect either. So I'm assuming 15W is just too much light for these glasses to block safely. Which is strange as OD6 should reduce the light to 0.00001% of its original strength (0.0015mw)
My question is, is it safe to view the dot through these glasses? Or would I need glasses with a higher rating?
The dot is quite bright still through the glasses and does leave a dot in my vision for a few seconds after looking at it through the glasses. Is my math correct for the total light that should get through the glasses?
Thanks!
