I'm building my first 445nm laser and I've got these goggles: Laser Glasses - UV to Green Lasers Protection 190-548nm :: Laser Safety :: Dragon Lasers and the question: what is the safe power of 445nm laser with these goggles? is 1000mA/1W safe? thx | |||

They are OD - 4 at 445nm. Here is an interesting tool: RadiantShades for Blue and Green Lasers The OD Calculator says you need an OD of 2.3 to turn 1000mw into 5mw Hope this helps
