How to choose the laser protective glasses

A laser is alight body with radiation, which is found to be used in our lives. But in anycase it is certainly the radiation. Today, Laser safety glassesworkers for you to explain laser goggles stagnation prospects, to bring you thesupport must expect.

                                         

蓝洞棋牌苹果手机With the lasertechnology used in military and civil field is broad, laser protection skillhas attracted more and more attention, the increasing variety of laserprotective materials. From the protection principle, in front of laserprotection data can be divided into three categories: one is based on theprinciple of linear optical laser protection, it includes attraction type, typeand attraction / albedo albedo composite; two is the laser protection principlebased on nonlinear optics, it is important the use of three order nonlinearoptical effects, including nonlinear albedo attract, nonlinear refraction,nonlinear scattering and nonlinear transformation; three is based on theprinciple of laser protection.

Has thecharacteristics of strong, the position of laser monochromaticity, coherenceand so on, making it in the military, light industrial and medical field hasbroad use. But it is the characteristics of the Department of the laser hasalso formed a great threat to the human body. Human eyes are the most sensitiveto the laser organ, because the eye focusing effect of light on the retina canmake the energy density increased 105 times, so the low dose can causesignificant damage on the retina caused increased eyesight and even blindness.How to continue the ineffective laser protection, become people's most concernedabout the issue, the relevant countries to develop a laser protection. As earlyas in 1962, the United States put forward some laser radiation limits.

China's use ofthe mandatory norms of laser insurance:

蓝洞棋牌苹果手机CJB-2408-95laser protective mirror protection performance testing steps

GJB-1762-93laser protective mirror to physiological health protection

Laser insuranceregulations for 5524-91 JB/T Laboratory

Laser protectivemirror type

There are manyvarieties of laser protective mirror, the opposite of the information, theprinciple of different, the use of the opposite. Therefore, to provide thelaser invalid protection, must according to specific application to continue toproper selection of laser protective glasses.

Choose the doormirror, according to the maximum input power (or energy), the laser beamdiameter, laser pulse time and other parameters to determine the maximumradiation input or the maximum amount of radiation. Then, according to thecorresponding time span and the maximum allowable amount of radiation shine(shine eye limit) to determine the mirror the minimum optical density value,and then selects suitable protective glasses.

Specificconditions of choice are important:

1, the maximumamount of radiation Hmax (J/m2) or maximum radiation degree Emax (W/m2);

2, a certainprotection span;

In 3, theoptical density value of Dmin to the corresponding protection span;

4, the nonsymmetry of the protective lens, asymmetric, the incident light effect, etc.;

5, the power ofanti laser radiation;

蓝洞棋牌苹果手机6, visible lighttransmittance;

7, structure andshape.

With the lasertechnology used in military and civil field is broad, laser protection skillhas attracted more and more attention, the increasing variety of laserprotective materials. According to the protection principle, the laserprotection materials can be divided into attractive, reflective and attractive/ reflective composite.

Above is thework of the Lasersafety glasses for everyone to illustrate, for thelaser protection mirror the prospect of stagnation. We expect everyone to seeafter the support, then we want to know more about the class of common sense.Please pay more attention to us. We are dedicated to serve you.
