A laser is a light body with radiation, which is found to be used inour lives. But in any case it is certainly the radiation. Today, Laser safety glasses workers for you to explain laser goggles stagnation prospects, to bring you the support must expect.
With the laser technology used in military and civil field is broad, laser protection skill has attracted more and more attention, the increasing variety of laser protective materials. From the protection principle, in front of laser protection data can be divided into three categories: one is based on the principle of linear optical laser protection, it includes attraction type, type and attraction / albedo albedo composite; two is the laser protection principle based on nonlinear optics, it is important the use of three order nonlinear optical effects, including nonlinear albedo attract, nonlinear refraction, nonlinear scattering and nonlinear transformation; three is based on the principle of laser protection.
Has the characteristics of strong, the position of laser monochromaticity, coherence and so on, making it in the military, light industrial and medicalfield has broad use. But it is the characteristics of the Department of the laser has also formed a great threat to the human body. Human eyes are themost sensitive to the laser organ, because the eye focusing effect of light on the retina can make the energy density increased 105 times, so the low dose can cause significant damage on the retina caused increased eyesight and even blindness. How to continue the ineffective laser protection, become people's most concerned about the issue, the relevant countries to develop a laser protection. As early as in 1962, the United States put forward some laser radiation limits.
China's use of the mandatory norms of laser insurance:
CJB-2408-95 laser protective mirror protection performance testing steps
GJB-1762-93 laser protective mirror to physiological health protection
Laser insurance regulations for 5524-91 JB/T Laboratory
Laser protective mirror type
There are many varieties of laser protective mirror, the opposite of the information, the principle of different, the use of the opposite. Therefore, to provide the laser invalid protection, must according to specific application to continue to proper selection of laser protective glasses.
Choose the door mirror, according to the maximum input power (or energy), the laser beam diameter, laser pulse time and other parameters to determine the maximum radiation input or the maximum amount of radiation. Then, according to the corresponding 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.
Specific conditions of choice are important:
1, the maximum amount of radiation Hmax (J/m2) or maximum radiation degree Emax (W/m2);
2, a certain protection span;
In 3, the optical density value of Dmin to the corresponding protection span;
4, the non symmetry of the protective lens, asymmetric, the incident light effect, etc.;
5, the power of anti laser radiation;
6, visible light transmittance;
7, structure and shape.
With the laser technology used in military and civil field is broad, laser protection skill has attracted more and more attention, the increasing variety of laser protective materials. According to the protection principle, the laser protection materials can be divided into attractive, reflective and attractive / reflective composite.
Above is the work of the Laser safety glasses for everyone to illustrate, for the laser protection mirror the prospect of stagnation. We expect everyone to see after 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.
