Howto choose the Laser safetyglasses, laser protective glasses have a variety of types, differentmaterials, different principles, applications are also different. Therefore, toprovide effective protection of the laser, we must make a reasonable choiceaccording to the specific requirements of the use of laser protective glasses.
Choosethe door mirror, according to the maximum output power of the laser (orenergy), maximum output irradiance or maximum exposure to determine the beamdiameter, pulse time and other parameters. Then, according to the maximumallowable exposure and the corresponding wavelength of irradiation time (eyeexposure limits) glasses determine the minimum optical density value, andselect the appropriate protective glasses. The specific conditions of choiceare mainly:
1,the maximum amount of radiation Hmax (J/m2) Emax (W/m2) or the maximum irradiance;
2,specific protection wavelength;
3,the optical density value of Dmin to the corresponding protective wavelength;
4,the non - uniformity of protective lenses, non - symmetry, the incident lightangle effect, etc.;
5,anti laser radiation ability;
6,visible light transmittance;
7,structure and shape. Laser protective glasses, laser protective glasses, laserglasses, laser protection,protective glasses, we have only a pair of eyes, please pay attention to theprotection!
