Whydo many people choose glasses are different, why do some people choose laserprotection mirror? Will there be such a feeling? We can look at Oh: glassesmainly to prevent laser damage to the eyes. Because laser energy is highlyconcentrated, the role of the eye is very dangerous, and even the risk ofblinding, so laser workers must wear laser goggles laser protection glasses.
Lasergoggles are mainly absorbent, reflective, compound, explosive, photochemicalreaction, glass-ceramic and other types. Absorption is in the glass or plasticlenses by adding a variety of absorbent, absorb the laser, so that it can notpass. Reflective is the lens coated with a high refractive index of the dielectricfilm, when the light to the dielectric film, the interface of all the reflectedlight phase are the same, so that the wavelength of light reflection, both toreflect the laser to achieve protective glasses The purpose of the othervisible light has a high ability to pass.
Thecomposite consists of two reflective dielectric films, separated by a layer ofglass that absorbs the color, suppressing unwanted internal reflections betweenthe two reflective films. This kind of glasses on the laser protectionperformance is better, the safety factor, suitable for large and medium powerlaser protection.
Explosiveis coated with a layer of explosives on the lens. When the incident laserintensity reaches a certain value, the rapid detonation to play the role ofshielding the laser, used in the military to prevent laser weapons hurt theeyes.
EachLaser safety glasses have their owncharacteristics, generally only to prevent a wavelength of the laser, a fewanti-two or more wavelengths of the laser, it must be based on the use of thelaser, use the appropriate laser goggles.
