I'm curious what the safety standards are for building a Class 4 laser. I was directed to document:" ANSI standard, Z136.4" google didnt show me anything consistent. any of you have access to the above?
Considering that these documents are sold at high prices (usually around 150$ for the ".4" only part, and over 300$ for the ".1-.4" set (the ANSI site sell them for $336 ..... cheap, for a 3Mb document ), is not so difficult to see why there's no copies from google .....
Probably you can find more about this from some universities sites, that uses ANSI standard documents, and cites them in their own articles ..... i've found that this searchengine site sometimes have some decent links from universities documents, as example, but my english is relatively low, so you have to judge yourself if the results worth the effort.
Boomarked! Thank you, always like those site.
I use this one, which
is nice because often you can just download (for free) a cached PDF
of the document you're looking for. This one is nice too, but only when I'm behind a University-IP, otherwise it's £$€...
