Laser has high brightness, monochrome, high coherence, high precision and high precision. It is a scientific research equipment often used by researchers and plays an important role in our life. Improper use of laser pen will cause serious damage to people's eyes and skin, as well as explosion and fire. The correct use of laser is an important event for human security. In the laboratory, we have three kinds of lasers exposed out of sight. The wrong use of this laser will cause little damage to the eyes. In the laboratory with three kinds of lasers, we need to pay attention to the following points: 1. Do not aim the laser at your eyes or directly at the laser. Without preparation, the laser cannot work. If the laser is not used, try turning it off or blocking it with a reflector. In addition, the adjustment of infrared or ultraviolet laser shall use laser monitor.
Laser products include Laser pointer, optical discs, bar code scanners and laser pens. It is reported that Apple Daily News 2015 (see the conclusion published in the newspaper article). Experts pointed out that in order to jointly train the laser beam, it needs 5 to 10 MW, while monitoring the laser beam is enough for interstellar about 20 MW. In addition, according to the existing information, the green laser pen can only feel warm on the Internet. If the beam is 5 seconds (about 15 cm), the blue laser rod can burn 100 MW and the green laser arm can burn for 1 second (about 15 cm). In order to protect the health of teenagers and children and avoid personal and property damage to teenagers and children due to unqualified toys, a 20-day special rectification of the laser pen market was carried out. I hope you can use the laser pen legally and don't hurt yourself.
Having all the energy and converting it into light energy is impossible to waste energy. Moreover, documents and clothes are unlikely to show signs of fading. The green pointer is very prominent and can be seen well from a distance. Even in places where many people use laser pointers, you can make your pen stand out. It is a laser oscillator, divided into 1 to 4 grades, with an output power of about 0.2 mW to 500 mW. The equipment commonly referred to as the green laser pointer refers to Class 1 and Class 2. The advantage of super blue laser pointers is that they look the brightest under the same output. It can be said that in the case of the same brightness, the lowest output is sufficient.
