Where can I read the blue laser pointer review?
The brightness of the green laser pointer is 8 times that of the red laser pointer. At night, you can see the blue light from your hand to the sky. Astronomy enthusiasts can enjoy the interpretation of constellations and beautiful starry sky through the green laser pointer pointing at the stars in astronomical observation and starry sky observation. In addition, there are many people who use it a lot during the day, and it doesn't light up when using it at night. Laser pointers made of semiconductors are extremely sensitive to temperature. If the temperature is too low, the laser may not turn on normally. At this time, it is best to hold the laser pointer with your hand and raise the temperature by 20°C. Conversely, if the temperature is too high, it will be better to lower the temperature after a period of time. In addition, the green laser pointer is prone to power consumption, so buy a rechargeable battery for the laser pointer.

Do not irradiate your eyes directly with green laser pointer light, even a laser with 1 MW output. However, it can be said that in the range of use based on general common sense, lasers below the 3R class are not particularly dangerous. Class 3B and above can be said to be a laser class, requiring users to have a firm awareness of laser safety, such as paying attention to the use environment. Class 1 laser that is safe under reasonably foreseeable driving conditions. No matter what optical system (lens or telescope) is used to collect light, it is a safety level for the eyes, and no special measures are required except for attaching a label marked as level 1.
