Ask at alt.lasers and Mr. Goldwasser or Mr. Carlen will probably insist you get goggles. I googled, but I can't get a link to the gov. specs, and I'm not going to hunt it down fer you, unless you pay (=).

Get goggles. 10mW is borderline for eye damage before blink reflex closes the eye. 200mW is seriously dangerous if you get a look at it. -- Dirk The Consensus:- The political party for the new millenium http://www.theconsensus.org | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
