Description
Laser Diode Module – 5mW 650nm 5V Red
This 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 lens is adjusted and glued by a strong glue stick, which can work directly after connecting to a 5 V dc power supply.
