Yes that is true I don't understand why hap is upset about the fact that I came here for help on a laser not glasses
These is no need to pick on Hap, he just want's to make sure you have good safety glasses.
Think about it, if you knew all about safety glasses you should know all about lasers too, some people actually think sunglasses are sufficient, but that is incorrect.
Hap would like to know as would I just what kind of glasses you have?
Did you know that green dpss lasers use an 808nm pump diodes that's 500% the final output and a 2 part crystal, the 1st half converts 808nm to 1064nm, the 2nd half that's bonded to the first doubles 1064nm to 532nm.
That's right 532nm is actually the higher frequency, twice that of 1064nm because that is the distance between waves.
In short simply having safety glasses that attenuate 532nm may not be enough if your dpss laser produces any IR laser leakage.
Now if you were to use a 520nm direct laser you would not have any IR leakage.
So do you have safety glasses that center on 520nm or 532nm?
Do you have IR filters to wear under/over your glasses? Are they certified?
You may find this hard to believe, but some people lie about having safety glasses.
