Thereare many types of laser protective goggles, the information is not the same,different principles, applications are not the same. Therefore, in order toprovide useful protection to the laser, the laser goggles must be selectedreasonably according to the detailed requirements. Choose the door mirror, themaximum laser output power of the primary basis (or energy), beam diameter,laser pulse time parameters determine the maximum output irradiance or maximumexposure. Then, according to the maximum amount of the corresponding wavelengthand light irradiation to time (eye shine limit) concluded that glasses theminimum optical density value, and select suitable protective glasses.
The detailed conditions of selection are:
1,the maximum amount of radiation Hmax (J/m2) Emax (W/m2) or the maximumirradiance;
2,specific protection wavelength;
3,the optical density value of Dmin to the corresponding protective wavelength;
4, the protective lens non-uniformity,asymmetry, the incident light angle effect;
5,the ability to resist laser radiation;
6,visible light transmittance;
7,structure and shape.
Laserprotective glasses offer: now on the market compared to famous laser protectiveeyewear brand bangshidu, Rui grams and Haobang, according to brand, function,material factors such as quotation from tens to hundreds of pieces.
