General information on laser pointers
The small width of the beam and low power of typical laser pointers make the beam itself invisible in a reasonably clean atmosphere, only showing a point of light when striking an opaque surface. Some higher-powered laser pointers project a visible beam via scattering from dust particles or water droplets along the beam path. Higher-power and higher-frequency green or blue lasers may produce a beam visible even in clean air because of Rayleigh scattering from air molecules, especially when viewed in moderately-to-dimly lit conditions. The intensity of such scattering increases when these beams are viewed from angles near the beam axis. Such pointers, particularly in the green-light output range, are used as astronomical-object pointers for teaching purposes.

Product Applications
650nm 5mW Red 6mm Point Laser Module
The principle of laser emission and the particularity of the production process determine that the laser has the characteristics that ordinary light does not have: three good (good color, good coherence, good directionality) and high (high brightness).
The laser has good directionality and high brightness, and can be widely used in various occasions. The series of laser tubes are convenient, intuitive, practical, easy to install, stable and reliable
