Stop using the laser pointer b
English Public
In the 1960s, mankind created the first powerful laser indicator. In more than 40 years, more than 100000 MW blue laser has made remarkable progress in variety and characteristics. It also promotes the development of many new disciplines and the formation of a series of related disciplines. According to international standards, lasers over 5 MW are harmful. The output power of the Laser pointer emitted in the visible wavelength range is 1 MW, which belongs to level 2 and the output power is 3R. Lasers exceeding 5 MW are classified as category 3b and require additional safety and precautions, such as wearing appropriate laser goggles.
Laser pen in school environment is a very useful learning tool. In case of improper use, there is often a risk of visual impairment. Frequent use of this equipment will cause people's concern about its safety, especially around the eyes. Heavy duty laser pointer is a relatively small visible laser, which is usually used to express topics of interest in classes and demonstrations. They are widely distributed in the school environment and are very useful learning tools. The decline in the price of 1000 MW laser has also increased the consumption of ordinary people. If not used properly, the 1000 MW green laser indicator will burn the retina, which is very important to the eyes.
It is important to let the public know the risks of misusing Green laser pointer, rather than using them as toys. Fortunately, the most common problem with laser marking eyes is not permanent trauma. If you extend the time, your eyesight will also be seriously damaged. Most 16340 batteries used for laser pens have low power, but if it focuses on the retina through the prism of the eye, it will cause damage. Continuous observation of the laser through a fully dilated eye within one minute can cause retinal burns. Reduced visibility is undoubtedly a danger and should be used with caution.
