Sells a lot of high power laser pen
Thus the green laser pen has the best choice for viewing stars because of its high brightness and visibility of the laser beam can be used with a lot of tools to watch stars and astronomical studies. All for astronomical selection researchers and enthusiasts use power at 1 mW to 1000 mW laser pointers indicator output power, and such a laser beam can be seen as long as 100 miles away. Astronomers can use green color laser to see the stars and constellations in the sky high, the beam is very bright, people clearly clear the celestial bodies. This quick and easy targeting locator can make you feel that your naked eye almost touches the stars.
The green beam can help you clearly see the celestial bodies and also give you astonishment surprises in astronomy. Viewstar is really a wonderful enjoyment of life, and astronomy enthusiasts should pay special attention when close to the sky plane, should always remember to take positive measures to protect your eyes. Because the laser pen has a strong output performance, to avoid being hurt. In a wonderful time, laser glasses are always necessary to help you study astronomy.
In addition, many people are faced with the problem: the day of the star pen correctly inserted into the night, his “no electricity”? Is a very sensitive to the temperature of the semiconductor, the laser pointer will not work, The temperature increases, the pin is if they are not working properly in a position, then maybe the battery is replaced.Unlike the ordinary green laser pointer red laser pointer, the output intensity is much higher than the overall brightness of the red laser, red laser pointer times the number of times. Green laser pointer, light show in the night sky, you can pierce the sky You can see the bright green light, astronomers can use it to refer to stars, also known as “refers to the Stiftrolle play.” It pierced the sky at night So you can find you in the vast sky to lead a complex day star what you want.
