Inquiry (采购产品): Custom IR Lens OmniGuide Inc., a company in Cambridge, MA making systems for minimally invasive CO2 laser surgery, needs a focusing lens at 10.6 microns. The lenses we currently use are ZnSe with an AR coating containing Thorium Fluoride. The problem is that under standard sterilization conditions (submersion in a flowing mixture of hydrogen peroxide and acetic acid at 50 C) the Thorium Fluoride dissolves. Do you sell any CO2 lens that has an AR coating that does not contain Thorium Fluoride? We don't care what materials the lens and AR coating are made of, as long as they withstand the sterilization procedure. Our current lenses have a 3" focal length, are 0.75" in diameter, and have an edge thickness of 0.07". We would be open to other dimensions.
