Astronomy Tool – Green Laser Pointer

For any one of the astronomy fan, green laser pointer would be always an astonishing tool for their astronomy research. Green laser pointers ranging from 1mW until 150mW are all available for those of astronomy lover’s use for stargazing or astronomy research.

Although people can choose both red laser pointer and green laser pointer for their astronomy work, yet more and more people would like to choose green color laser pointer owing to its high brightness and long distance beam visibility. The 532nm green laser pointer is powerful enough to watch stars and other celestial object in the night sky. People can have a clear observation of the star via the long visible green color beam, and the beam is so bright and visible that you can just feel your eyes are nearly touching the star.

Usually a low power 5mW green laser pointer will be chosen to watch stars in the night sky for personal use or on condition of good atmosphere visibility. On condition of bad weather condition such as heavy fog, serious air pollution, or astronomy researches with a large group of companions followed, higher power green laser pointers with an output power ranging from 100mW to 150mW are very necessary. The higher the power, the quick beam dispersion it will be. The visible beam of green laser pointer could reach the celestial object only in a few seconds, and which is also be used by astronomers to watch spot in those of low clouds.

Green laser pointer is not only used to watch stars but also very useful while mounted on telescopes, which will help astronomers make a fast and accurate pointing of celestial objects. The use of green laser pointer along with telescope will help astronomers avoid a lot of trouble of waving arms, explaining a lot while pointing a certain celestial object. While watch stars in the night sky with a higher power green laser pointer, people should always wear laser safety goggles to protect eyes from the radiation of strong and powerful beam.

How to Get a Cheap Laser Pointer

If you want a laser pointer which is capable to burn plastic, cut electric tapes, light matches, pop balloons, and with a visible beam of about 60 miles or even longer, you’d better choose a 200mW green laser pointer. Anyway, you should pay enough attention whenever choosing a green laser pointer. A good quality laser pointer from a reliable supplier would by your best choice.

Shoddy Laser Pointer

From the first appearance of 5mW green laser pointer, a large number of laser pointer manufacturers and distributor are flooded into the laser market. Various kinds of laser pointer with multiple colors and different output power have sprung up all over the world. It is a fortunate that a large variety of shoddy laser pointers are also flooded into the market, which has made it much difficult for people to separate high quality laser pointers from those of shoddy lasers.
The quality is especially important for a laser pointer. Infrared light is a potential danger of the shoddy laser pointer, which cannot be noticed by people until it is too dangerous. 532nm green light is the most visible color the human eyes and green laser give out only green color light, while the shoddy green laser pointer would give out not only green color light but also infrared light. The infrared light from shoddy laser pointer will hurt human eyes without being noticed until it’s too dangerous. Anyway, it is really a dangerous thing to hold a green laser pointer in hand.
There is no different from genuine green laser pointer and shoddy laser pointer while checking from their appearance, while the power is quite different if you compare them together. For example, you may have a doubt that how a shoddy laser pointer can have an output power of 200mW while might be less bright than a 50mW green laser pointer. This is just the fact. The shoddy laser pointer is not as bright and powerful as a genuine green laser pointer with the same range of output power. The shoddy laser pointers give out a lot of infrared light which can not seen by human eyes. Laser pointers can be distinguished by the light brightness.
Whenever you are choosing a green laser pointer you should pay enough attention if it is a shoddy laser pointer. On condition that you have got a high power green laser pointer which is not so bright, it might be a shoddy laser pointer and is most likely giving out a lot of dangerous infrared light. Just do be careful to choose the most suitable green laser pointer at a reasonable price and always remember protecting eyes from the strong radiation of the powerful beam.
