Beam expanders developed for CO2 laser are made by ZnSe material which has the highest transmission for CO2 laser. We provide a wide range of magnifications from 1x to 20x. With dedicated mechanical structure, the internal lenses don’t rotate during adjustment, which ensures the best alignment accuracy. Adjustable ring with scales makes it more convenient for user’s operation.
