Collezione: Laser Pointer

A green, red, blue laser pointer or laser pen is a small handheld device with a power source (usually a battery) and a laser diode emitting a very narrow coherent low-powered laser beam of visible light, intended to be used to highlight something of interest by illuminating it with a small bright spot of colored light.

Laser pointers are a great tool for such tasks as conducting business presentations, lectures, speaking engagements, and stargazing.
