The safety level of the laser is generally divided into 4 levels.
ClassI: Low output laser (power less than 0.4mW). Basically, it will not cause harm to the eyes, and it can guarantee the safety of design without special management. ClassII: Low-output visible laser (power 0.4mW-1mW), usually less than 1mW of laser, can cause dizziness and can not be considered, with closed eyes to protect, generally eliminate symptoms. Do not observe directly in the beam, or use a laser of less than 1mw to directly illuminate other people's eyes, avoiding the use of Yuanyuan equipment to observe Class II lasers.
Class III has Class IIIA and IIIB: Class IIIA is a continuous laser with visible light and a laser beam of 1-5mW. Avoid using the Yuanzhi equipment to observe the I laser. This may increase the danger. As with Class II, do not directly in the beam. Do not use the Class IIIA laser to directly illuminate other people's eyes. Class IIIB is a continuous laser of 5-500mW. It is dangerous to observe directly in the beam. Do not use Class IIIB laser to directly illuminate other people's eyes. This is even more dangerous.
ClassIV is a high-output continuous laser (greater than 500mW), higher than the third level, there is a danger of fire, and diffuse reflection is also dangerous, especially worth noting. Children should avoid watching such lasers directly. Summary: Class II, Class IIIA, Class IIIB, Class IV products have certain hazards. Please use them under guidance and supervision. Children should pay more attention. Please use them under the supervision of parents or other guardianship.
