Alexandrite lasers used in cosmology produce a wavelength of 755 nm.  Oftern 1064 nm are used in combination such as with Candela Alexandrite lasers.  The LG-346 and LG-346N laser safety goggles protect against both 755 nm and 1064 nm with a very high OD 7+ LB7 level of protection which is 10 million times.

More information on the LG-346 and LG-346N laser goggles can be found via the below links.  If you have any questions feel free to contact us on info@dioptika.com and one of our laser safety experts will be happy to help.
