Where to buy your strong green laser pointer on the internet

Today, the green laser pointer is the world's most popular laser pointer because the green light than red light 6 times more clearly than red light beam, while the price is cheaper than a lot of blue and yellow. Users typically use green laser pointers.
The wavelength of the emitted light green light pen is 532nm, laser type is a class IIIA, uses two AAA batteries. Brightness 300mw laser pointer green is more objective, so the eye is relatively high risk, the higher the performance, the more dangerous. Generally 5mW is widely used, the US market may use 5mW laser pointers over 5mW in need through special approval. There is no strict restriction in the country that we are asked to pay special attention to the safety of users who are not facing the eye or other hazardous area, but also to prevent the reflected laser light from entering the eye.

Is this green laser pointer recommended?

Strong green laser pointer



For the astronomy enthusiast should decide how much more power and price does the star spring relate to the requirement that the star hit them? Personally think 20mW to 50mW power more suitable, 50mW more power under dim indoor conditions able to feel particularly blatant. The main prize green 5000mw laser pointer related to its bandwidth and stability in the narrower bandwidth, the more expensive price, but the human eye cannot distinguish the difference, at this point bandwidth therefore economically strapped friends choose power 50mW or less, the price laser pointer is 100 yuan less more suitable. In addition, the laser pointer is usually relatively large power consumption, in line with the principles of environmental protection and the savings that come with a pair of good battery is also necessary.

In addition, many people may be faced with this problem: the day the star pen is properly used, how into the night, "no power" from it? Refers to the star spring to produce medium is a semiconductor laser, various properties of semiconductors is very sensitive to temperature, at a lower temperature, high power laser pointer will not work, then just hand over the laser pointer for a moment, let temperature rise above 20 degrees, the pen will be able to work properly, if not then maybe in terms of replacing the battery.
