SPT laser is the first manufacturer in the world to develop and produce coaxial red light indicating CO2 laser tube. The red light module is designed as a separate 5V DC power supply. It can also obtain power from the existing laser power supply or control card.

During laser lens correction, the laser transmission path can be accurately visualised, which makes the adjustment of the optical path more precise, convenient, and safe thanks to its red light preview and positioning functions.
