20mw royal purple 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.

1.Press the button to use.
2.Do not look into the aperture of the laser beam,and do not aim into eye!
3.Do not repeat to switch the laser pointer within 1 min, otherwise it will shorten the lifetime of the laser pointer.
4.Take off the battery and Keep out of reach of children!
5.Charging or changing the battery once the laser beam brightness seriously drop!

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
Contradistinction of the green, red and blue violet laser pointer:
Brightness: green>red>blue violet
Price :red< green< blue violet
Poly thermal performance: green< red＝blue violet
Stability: green< red＝blue violet
