650nm Laser Diode Rotary Switch 2mm Support remote control typeThis is a 5 mW laser diode module that emits a small intense focused beam of visible red light. The module can be used with an Arduino and photoresistor module to perform basic remote signaling. It is breadboard friendly and low cost having a wavelength of 650 nm and an operating voltage of 5 V. The laser head is composed of a light emitting tube, condenser lens, and adjustable copper sleeve and it is assembled when delivered, the focal length of the
