Instruction:
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.

Application:
Can be used in museums and all kinds of exhibitions, a very good guide for your travelling, your best Companion.
Best guide for the climbers and people in mountainous areas. Good tool for pointing out the faraway target and sending out the SOS signal, making your travel more fun.
The beauty beam light is extreme suitable use at night, which can point out the very right position of the star you are looking. A very good star-pointer
This laser can measure you the accurate position of the building in the faraway distance by avoiding going close to the dangerous field. Truly an very ideal replacement for your monitoring alive.
This is a commonly used product for meetings and conferences, let you speak out freely.
This is the commonly used product for demonstrations and presentations in classes, and other activities, making listeners feel release.

Notice:
405nm Wavelength laser (blue-violet light) is very dark, if you need brightness laser pointer, please choose the red laser or green laser.
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!

NOTE:
1. The cheap royal purple laser can bright enough when you light it in normal temperature, so you had better do not light it continually in 30 seconds
2. 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
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
