I recently picked up a 10mw hughes hene laser on ebay, but I don't know its wavelength and would like to know it so I can get some goggles. All it says on the tube is model no:3224h-pc and serial number 3110169 and made in march 1983, I've googled but to no avail. Can anyone help?

Great, thanks for that, looks like I have a linearly polarised 632.8nm laser then.
