Now the day we use needle about laserapplication has reached the appropriate good height for us now is now daysdevelopment cannot do without using the laser light on substance of thisspecial use, we can find out days because the laser efficiency offers endlesschanges to a great extent for us the day. But in our view of Laser safety glasses now most people actually in the process ofusing these diversified laser equipment from the neglect of human body on theformation of the laser damage, even when using the laser to know is very simpleand convenient, but for us the damage is exposed and not rehabilitation, can besevere blindness.
Laser protective glasses have a variety oftypes, the use of information on the contrary, the principle of different, theuse of the occasion is also the opposite. Therefore, to provide protection forthe laser must be invalid, with proper choice to continue to use the lasergoggles. Choose the door mirror, first according to the maximum input power forthe laser (or energy), beam diameter, laser pulse time and other parameters todetermine the maximum radiation input or the maximum amount of radiation. Then,according to the maximum allowable amount of radiation corresponding span andirradiation time (eye exposure limits) to determine the mirror the minimumoptical density value, and select appropriate protective glasses. The choice ofthe detailed conditions are important to have:
1, the maximum amount of radiation Hmax(J/m2) or maximum radiation degree Emax (W/m2);
2, a certain protection span;
3, the optical density value of Dmin to thecorresponding protection span;
4, the non symmetry of protective lenses,asymmetric, the concept of the incident light effect, etc.;
5, the power of anti laser radiation;
6, visible light transmittance;
7, structure and shape.
With the characteristics of laser damage cannot be ignored in many types of equipment using the same data process, and moreimportant is our life has not been the lack of a variety of laser protectiveequipment, but we do not know how to use the laser protection, as long as thetime Shanghai has not no laser inverse recovery only know using laserprotective equipment, have to say is how sad thing. Laser protective glassesexpect us to have a clear understanding of the laser, the particularity andpracticality of the laser is indeed very strong, but can not be lost on thelaser.
