Where do you buy your strong green laser pointer online
Today, green laser pointers are the most popular laser pointers in the world, because green light is 6 times clearer than red light beams, and the price is much cheaper than blue and yellow. Users usually use a green laser pointer.
The wavelength of the light-emitting green light pen is 532nm, the laser type is class IIIA, and it uses two AAA batteries. The brightness of the high power laser pointer is relatively objective, so the risk to the eyes is relatively high, and the higher the power, the more dangerous it is. Generally, 5mw is commonly used, and the US market 5mw laser pointer can exceed 5mw and requires special permission. The country does not have strict restrictions, requiring us to pay special attention to the safety of users, not to ignore the eyes or other vulnerable parts, and to prevent the reflected laser from entering the eyes.

Do you recommend this green laser pointer?
For astronomy enthusiasts, it should be decided how much the performance and price of a star feather is related to the requirements of starstrike it? Personally think that the power of 20mw to 50mw is more suitable, and the power of 50mw can feel particularly obvious in dim indoor conditions. The green laser pointer is related to its bandwidth and stability. The narrower the bandwidth, the more expensive the price is, but the human eye cannot distinguish it. At this time, the bandwidth, therefore, friends who are financially strapped choose the power below 50mw and the laser pointer below 100 yuan. The price is more suitable. In addition, laser pointers generally consume a lot of power. In line with the principle of environmental protection and power saving, it is also necessary to have a good pair of batteries.
In addition, many people are faced with such a problem: the star needle is used correctly during the day, why is it "out of power" at night? The medium produced by the star pen is a semiconductor laser. Semiconductors of different properties are very sensitive to temperature. At a lower temperature, the laser pen does not work. Then hand over the laser pen for a while and let the temperature rise to more than 20 degrees. Can the pen work? Works fine, if not, maybe in terms of battery replacement.
Powerful green laser pointer
Different from the common green laser pointer, the output intensity is obviously several times higher than the overall brightness of the red laser pointer. The green laser pointer shows light in the night sky, and you can see a bright green light flashing in the sky. Astronomers can use it to refer to the stars, also called "pointing pen". It shuttles through the starry sky at night, allowing you to find the stars you want in the vast starry sky.
This green laser pointer is awesome!
The quality of the laser crystal is particularly important. The low cost is the reason for the low price, so that the large number of laser crystals manufactured are of poor quality. Inferior green laser pointer are inexpensive, but there is always a danger initially once one chooses an inferior laser crystal. A sloppy laser pointer is not as bright as a real laser pointer for the same output power range. Sloppy laser crystals are usually made without infrared light, which is quite dangerous and people don't notice it until they seriously injure their eyes. Therefore, you should pay special attention to whether the laser crystal passes through the IR filter. Infrared filters and green laser pointers are not only much brighter than low-quality lasers, but also the safest choice for laser fans.
