The desktop fiber laser engraving machine is the third generation laser marker system. It adopts optical fiber laser to output laser and realizes marking function through high speed scanning galvanometer system.The fiber-optic laser stippling machine features high electro optic conversion efficiency, air cooling, small size, materials and widely used in the fields that have high requirement on depth, smoothness and fine details, such as stainless steel mobile phone overlay, clock and watch, mould, IC, mobile phone keypad, parts, and tools. Bit map marking can engrave beautiful pictures on the surfaces of metal and plastic, and the marking speed is 3 to 12 times of the speed of traditional first generation lamp pump marker and second generation semiconductor marker. Fiber optic laser stippling machine is used to output laser, featuring high electro optic conversion efficiency, small size and high light beam quality.
