I have a large quantity of optics from Coherent. Many of these are Bounce mirrors for High power Ar/Kr multiline lasers. I also have alot of Zinc Sulfate lens blanks/windows. You can bud on any of these or if you want to make an offer, you can let me know by PM. http://search.ebay.com/_W0QQsassZche...ics.123QQhtZ-1
