Optical element laser cutting machine maintenance

Laser cutting machine optical element once even contaminated product stick on cutting small particle, the cleaning up on it is a very important and often overlooked problem, here are some key points: (cleaning 1) Lens cleaning: clean the lens paper bending into several fold, with a few drops of analytical pure acetone; Gently wipe the lens surface with wet lens paper, pay attention to not pressure lens with your fingers; Repeated several times until the lens surface clean, no dirt and residual traces left in a mirror; With dry air blow dry; When necessary to use a few drops of acetone wet paper roll into a bar and gently scrub the lens surface, in order to remove the dirt.
