Trust many people now have some knowledgeof our laser protective glasses, in the now prosperous society, the use oflaser skills too much, so in the selection of laser operation, we muststrengthen the protection of the eye, laser protective glasses, greatly improvethe protection of the eyes, reduce the effect of laser the eyes of the. Thepresentation of laser protective glasses, which is equivalent to a safe andsecure for our eyes.
With the extensive use of laser skills inmilitary and civil areas, the laser protection skills have become more and moreattention, and the variety of laser protection materials is increasing day byday. From the protection principle, the laser protection data can be dividedinto three categories: one is based on the linear optical principle of laserprotection, it contains absorption, reflective and absorption reflection type;the two is based on the principle of laser protection of nonlinear optics, itmainly uses three order nonlinear optical effects, including nonlinearabsorption nonlinear refraction, nonlinear scattering and nonlinear reflection;the three is based on the principle of laser protection transformation.
The laser has the characteristics of strongdirectivity, good color and good coherence, which makes it widely used inmilitary, industrial and medical fields. But it is these characteristics of thelaser on the human body also constitutes a great threat. Human eyes are the mostsensitive to the laser organ, because the aggregation effect of light can makethe eye retina energy density increased 105 times, so the low dose can causesevere damage on the retina resulting in reduced vision and even blindness. Howto carry out useful laser protection, we have become a very important question,various countries have developed a corresponding laser protection. As early asin 1962, the United States put forward some laser safety radiation limit.
Now China's use of the mandatory norms oflaser safety:
Measures for the protective function ofCJB-2408-95 laser protective glasses
Requirements of physiological healthprotection for GJB-1762-93 laser protective glasses
5524-91 JB/T laboratory laser safety rules
Based on our understanding of the laserprotective glasses on, we can make full use of laser protective glasses, letmore people to strengthen its utilization, walk in the forefront of thedevelopment, in the protection of more is to step on a big step in the developmentof our most standard for laser protection glasses manufacturing, so we can notthe same as the area of the laser glasses provide more choices.
