How to Choose Astronomy Laser Pointer

Posted on by

With the hot summer coming, night life has become one of the major themes of a day. Summer is the best season for astronomy researchers and fans to watch constellations in the night sky. Astronomy laser pointer might be a wonderful tool for those astronomy fans to have a clear stargazing and targeting. If you know little of laser diode technology about the application in astronomy, I hope these tips might be helpful.

Fist is the color of laser beam. Various kinds of green, red, blue, yellow, violet color lasers are all available in the market, while what kind of color should you choose? For astronomy, high brightness and long distance visibility are two major factors to be paid attention to. Green laser pointer has a medium wavelength of 532nm and the most sensitive color, so the beam of green laser diode has better diversity than any other colored laser diode device. As a result, green color laser diode has become the first choice of stargazing and pointer for astronomers.

Second is laser output power. Astronomy grade lasers are available from 5mW to 150 mW, so you can have a free choice of the suitable laser you need. The low power 5 mW is usually used in good atmosphere and for short distance observations. In condition of bad atmosphere, higher power laser is required so as to have a long visibility of celestial objects. You can choose laser pointers depending on the actual conditions.

Third and also the most important of all should be the quality. Low power has become the most competitive advantage of any commodity, thus it is a difficult thing to make sure of the reliable quality. A high reputation laser supplier will no doubt provide astronomy lasers with best quality.

Only laser pointers with high bright beam and good quality can really have a good effect of star gazing and other astronomy researches. If you are an astronomy enthusiast, a cheap astronomy laser pointer is a perfect tool for your stargazing. You will have a good time during this hot season and enjoy yourself with the perfect astronomy tool – Green Laser Pointer
