Inquiry (采购产品): low wattage laser for wood trimming I am interested in purchasing a low wattage CO2 laser system that I could use to trim up to 1/2" diameter wood cores taken from trees. We do metals analysis of the annual rings and want to avoid metals contamination from the increment coring device. **** Hidden Message ***** larry benson 80303 Company: u.s. geological survey E-mail: lbenson@usgs.gov **** Hidden Message ***** lbenson@usgs.gov
