A laser pointer is a small laser designed to highlight something of interest by projecting a small bright spot of colored light onto it. The laser beam is not in itself visible from the side, but is visible as a result of light scattered by dust particles along the beam path. The small width of the beam and low power of typical laser pointers make the beam itself invisible in a reasonably clean atmosphere, showing a point of light when striking an opaque surface. Some higher powered laser pointers are faintly visible via Rayleigh scattering when viewed from the side in moderately to dimly lit conditions.
