Does the 532nm green laser marking machine produce radiation to the human body?

The laser marking machine is widely used in life. It can quickly leave a deep mark on the surface of the material to be marked, and a certain amount of smoke will be generated, even for hard metals, and it has a very powerful force. , The staff who have operated the laser marking machine feel the same. Some people think that the fiber laser marking machine is so powerful, the radiation is also great, it will cause harm to the human body, then the laser marking machine will produce radiation to the human body? Let’s learn about it. Take a moment.

Green laser marking machine

In the industrial production process, laser marking machines have different types and different radiations. They are generally divided into four levels. According to relevant standards such as CDRH, products with output power below 8.5nW are the first level, and those with 500mW and above are the highest level and fourth level. .

Operate normally according to relevant operating specifications, there will be no light radiation

First of all, as long as the first level is operated normally in accordance with the relevant operating specifications, there will be no light radiation, and will not cause any harm to the human body. The second level can control the limited radiation in the spectral region. The AEL value is equal to the value of the first-level laser marking machine in a quarter of a second in the radiation. The second-level laser marking machine needs to mark certain warning signs. , It is necessary to test the safety before the actual operation starts to ensure safety. 3a and 3b together form the third level, the human body will have a self-defense mechanism, especially after seeing the glare, 3a is relatively safe for people who can actively avoid the glare, and it is relatively safe for the naked eyes of the operators. It will not cause damage easily, but if the staff needs to use lenses and other instruments to observe the beam, it will cause certain damage to the eyes of the human body. The radiation generated by the 3b laser marking machine is higher than 200nm and less than 100 Ten thousand nm, as long as you look directly at the beam with your eyes, there is a chance of accidental injury. Therefore, the management of 3b type products is stricter, and there must be strict operating specifications. Finally, the fourth-level AEL is higher than the third-level, and the degree of danger is the highest. It will not only damage the eyes when looking directly, but also may cause damage to the eyes, skin and other parts of the human body under special circumstances. It will cause fires, etc., and its control and management are the most stringent.

The laser will not cause radiation damage to the body, and safety can be guaranteed

All in all, does laser marking machine produce radiation to the human body? Laser marking machine is a technological product, which includes fiber laser marking machine, CO2 laser marking machine, etc., and the corresponding materials and functions are also different. , After many years of practical use and testing, most models as long as they operate in accordance with the specifications, although there is a certain amount of radiation, but it can be controlled below the acceptable range of the human body, and generally will not cause radiation damage to the body, and safety can be guaranteed .
