With the continuous development ofsociety, the laser also appear thriving rise gradually, we have to trust ourlaser protective glasses have new know, following small series with us togetherto look at the variety and effect of laser protective glasses first, can helpmore people to strengthen the protection of the eyes, the expectation can makemore and more people know and have a new insight in the purchase of laserglasses.
Glasses to prevent laser damage to theeyes. Because the laser energy is highly concentrated, the effect of eye damageis large, and there is the risk of blindness, so laser operators need to wearprotective glasses laser laser protective glasses. Laser protective glassesmainly have absorption, reflection type, compound type, blasting type,photochemical reaction type, glass ceramic type and other varieties. Absorptionis in the glass or plastic lens to participate in a variety of absorbent,absorb the laser, so that it can not penetrate.
The reflective is plated with a group ofhigh refractive index dielectric film on the lens, when the light medium film,all reflective phase interfaces are the same, so that the light reflectionwavelength of the reflected laser can not only strengthen, achieve the purposeof protection glasses, other visible light has a very high transmissioncapacity. The composite consists of two reflective dielectric film, a middlelayer absorbing color glass separated, restrain the two reflection film withoutinternal reflection. This kind of glasses is good to the protection function ofthe laser, the safety factor is big, is suitable for medium and large powerlaser protection. Blasting is to coat a layer of explosive material on thelens. When the incident laser intensity reaches a certain value, the rapiddetonation in order to cover the effect of the laser, in the military toprevent damage to the eyes of the laser weapon.
Each kind of laser protective glasses havetheir own characteristics, usually only one laser wavelength, the laser canprevent a small amount of two or more wavelengths, so it is the necessary basisfor the use of lasers, choose appropriate laser goggles.
After the above small that can help morepeople know about the new laser protective glasses to prevent our eyes, sufferthe influence of laser, then speed up the pace as soon as possible for ourlaser processing of laser protective glasses effect, expect the aboveinformation can take to help us!
