No offense but I have plenty of other things I can spend $400 on. That'* just my opinion though.

What'* the OD rating of your magic goggles?
The OD rating is 190-380nm OD 5+ 488-532nm OD 2-3


I am taking your advice seriously. I may be returning this laser.

I found my hazard analysis (required to have this laser here at work, where I use it for laser safety training).

Direct view of the beam, a 45mw 532nm laser with our beam characteristics (divergence, power, etc) has a nominal hazard zone to the human eye of about 200 feet. In other words, if you accidentally swept it across an intersection, anyone within 200 feet has the potential for eye injury.

If you catch a reflection off of a piece of glass, and roughly half the energy is diverted, you've still only cut that nominal hazard zone down to 100 feet.

Beyond 200 feet, the beam has diverged to the point that the human aversion response would protect the 'victim' through the blink reflex and reaction to the pain.

Wow I had no idea they could be so dangerous. The one I just bought is 3 times more powerful than the one you described. I am suprized it was even legal for sale. I just thought it was cool not so harmful.

It'* NOT legal for sale. The FDA prohibits importing those except as a COMPONENT in a finished product using ANSI guidelines for safe install.

However, the FDA has no enforcement policy to prevent you from buying one from China, which is what you did. Wicked Lasers would never be able to sell them from US soil.
