As we know co2 laser is invisible, we cannot get the position of laser dot while laser engraving machine working. However, we need to know the accurate position before dealing with the material most of the time, then how can we achieve it? The special red dot pointer of Thunder Laser engraver cutter can help you to solve this problem. Thunder Laser engraver cutter use a special laser beam combiner to combine the 650nm wavelength of red light and the 1064nm wavelength of co2 laser engraving cutting machine into one path so the invisible co2 laser becomes visible. The red dot pointer helps you to clear the accurate laser position before cutting and engraving, to greatly reduce the deviation and to save your time and material waste.
