Green Laser Pointer for Astronomy Application

Various kinds of laser pointer are available from http://www.laserto.com, where a large variety of astronomy green laser pointers ranging from 5mW until 150mW are all available. The lower power green laser pointer is playing an important part among those of astronomy researchers and enthusiasts.
In majority of the time, 5mW green laser pointer is commonly used for simple stargazing in the night sky. Usually a lower power green laser pointer is simply useful under good weather condition. In condition of bad atmosphere such as big fog, heavy cloud, or serious pollution, a high power green laser pointer with an output power upper 75mW might be enough. While choosing a higher power green laser pointer, the beam would be visible in several hundred miles far away.

The high power green laser pointer would be powerful enough to watch stars and other celestial constellations clearly in the dark evening. With the help of high power green laser pointer, teachers have no need to wave arms and complain hardly while pointing a certain star in the sky, and the bright laser beam spot is bright enough to make a clear aiming of the target star. The green laser pointer has largely saved the time of astronomy research and improved the efficiency and accuracy of stargazing. Whenever choosing a high power green laser pointer, people should take enough care of the strong beam.
