Ordered myself an lzcb 200mW 532nm from lazerer the other day and decided to get myself a pair of these to go with it: Beginner Safety Goggles for 532nm / 445nm Laser
I was thinking ahead and was wondering if >5 O.D. is good enough for 1W of 445nm, or will I need better ones?
EDIT: better yet, I know the OD rating is a percentage of how much light is passed. Does somebody know the formula forfor it?
