5pcs 650nm 6mm 5V 5mW Red Laser Diode Module

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 lens is acrylic plastic and can vary somewhat in its ability to focus to a small spot. If necessary, the spot size can be focused by rotating the threaded brass lens holder in either direction.
