And the hot summer coming, night life has become a major theme of the day.Summer is the best season to see in the night sky in the constellation astronomy researchers and fans.Astronomy laser pointer may be a wonderful tool has a clear fantasy and positioning for the astronomy enthusiasts.If you know the small laser diode technology used in astronomy, I hope these suggestions can help.
The fist is the color of laser beam.Laser a variety of green, red, blue, yellow, purple color are available in the market, and what kind of color if you choose? For astronomy, high brightness and long distance visibility are the two main factors is the attention.Green laser pointers have medium wavelength of 532 nm and the most sensitive to color, so the beam of green laser diode has better diversity than any other color laser diode device.Therefore, the green laser diode has become the first choice of fantasy and pointers for astronomers.
The second is the laser output power.Astronomy class laser from 5 kW to 150 kW, so you can have a free choice of the appropriate laser need.Low power of 5 MW is usually used for good atmosphere and short distance observation.In the condition of no good atmosphere, high power laser is necessary, so long the visibility of objects.You can choose according to the actual conditions of the laser pointer.
Third, and most important is the quality of.Any goods of low power consumption has become one of the most competitive advantage, so this is a difficult thing, to ensure reliable quality.A high reputation laser suppliers will undoubtedly provide the best quality of astronomy laser.
Only a laser pointer and high bright light and good quality can really get a good effect and other astronomical star gazing.If you are an amateur astronomer, a cheap astronomy laser pointer is a perfect tool, let you be absent-minded.You will have a good time in the hot season, enjoy yourself and perfect astronomical instruments -- green laser pointer
