Check E-bay.......seen a few floating on there for around 80.00. If you need them very soon www.mfgcn.com [Axiz laser] sp? has them for around a $100. They are @6.5 O.D. @532nm. That will save reflections and accidents from your eyes. Get the highest optical density you can afford for the wavelength of the laser you are using. You only have one set of eyes. Horror stories abound on the web. Better safe than seeing with vision that resembles a poster board that has been shot with a shotgun. :!:
You are the only one that can make your dreams come true....and the only one that can stop them...A.M. Dietrich
