Laser pointer
text:
A laser pointer or laser pen is a handheld device that uses a laser diode to emit a narrow low-power visible laser beam to highlight something of interest with a small bright colored spot. The small width of the beam and the low power of typical laser pointers make the beam itself invisible in a clean atmosphere, only showing a point of light when striking an opaque surface. Laser pointers can project a visible beam via scattering from dust particles or water droplets along the beam path. Higher
