Laser Diode

It's a Laser Diode with an Adjustable Focal Length. A laser diode is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasting conditions at the...

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....
