Laser System for Precision Dot Matrix Etching This laser system is specially designed for precision etching on various materials to form required dot matrix. The light guiding plate with dense dot matrix is a very important part of the backlight sub-systems of LCD. Typically, the materials are stainless steel or nickel based alloy. Laser dry etching molding has many advantages over conventional chemical etching, including simple process, high positioning accuracy, high productivity and environmental friendly. Specifications: Laser operation model: Q-switched Cooling method: Air cooling Max speed: 500 dot/second Dot diameter: 40-80um
