Instruction:
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 in moderately to dimly lit conditions.
NOTE:
- The laser can be bright enough when you light it in normal temperature, so you had better not light it continually over 30 seconds
- Avoid direct eye exposure to laser beam (any contact to the human eye can cause permanent damage). Never expose your eyes or anyone else's to the laser beam
- Please put it away from children to avoid the danger by contacting. When do not use it, please take off the battery from the laser in order to avoid the damage by the children's contacting
