CO2 Laser Red Dot Pointer For 40W-150W CO2 Laser — Monportlaser
This red (650nm wavelength) laser diode module is easily powered by a 5V DC USB power supply or battery and can be used as a pointer, for illumination, and light therapy. Wires for the DC power are soldered to the 6mm brass laser diode housing. The module includes an internal 91-Ohm current limiting resistor, so no additional series resistor or current limiter is required. Simply connect 5V DC power to use! The Red lead is Positive (+), and the Blue or Black lead is negative (-).
