Commonly low powered green laser pointer is always wonderful choice for astronomy. For astronomy learners, they can use it as simple stargazer. Users can use 5mW green laser pointer to watch stars, constellations and other celestial objects in the night sky. In addition, for close distance observation, users can get a clear watch of low cloud dusts with a low powered green laser pointer.
However, when users are making long time continuous light emitting, green laser pointer has to be stopped after a few minutes continuous pointing. Usually the recommended operating time should be no more than 30 seconds and then 10 seconds stopping time. Users might have a doubt why red laser doesn’t need a short time stopping after continuous pointing. However, green laser pointer has to be stopped after continuous pointing. Usually 532nm green laser has bigger energy power consumption and bigger hot energy emitting. Once the operating temperature is too high, the stability of green laser crystal might be greatly affected. The most serious thing should be that the 532nm green laser diode might be burnt out seriously. As a result, users should be cautious enough while operating a laser pointer in hands. Only if users are obeying correct operating measures, green laser pointer can just bring the best light emitting result efficiently and successfully.
