Laser marking machine laser safety is a very important topic, almost all over the world the name of "safety first" banner in all industrial circle, although many places do not really go practice, will have to wait until an accident be on the alert, but for this irreversible damage to some businesses will conscience considerable attention, and in this laser marking machine industry, too, to know that the laser can be used as weapons exist, lethality and no representation on the small light source so weak, it should be said that if there is a problem, then the laser, the damage is very substantial, and generally speaking, industrial lasers are divided into four levels, four is the highest level.
Carbon dioxide laser for the laser radiation wavelength 10μm, and a solid laser as 1μm, such raw source is less than the human eye to capture, and would harm the human body, such damage may occur within a wavelength of 1μm solid-state lasers at greater risk, when the damage is not visible to the human eye wavelength beam through the eyes, resulting in more intense than some bright visible light, such damage after blasting the retina to withstand 5,000 times the force of going up! This is properly the completed blindness baa good rhythm, but relatively speaking, carbon dioxide laser laser beam is absorbed by the cornea of the eye, so security is greatly improved,
