What should laser protective glasses pay attention to

<p>In today's days, our application of laser has reached an appropriate and good height. For us, the development of today is inseparable from the application of laser, which is a special material light source. We can find that In the days because of the efficiency of the laser, we have provided countless changes to our days. However, in the view of our laser protective glasses, most people actually neglect the damage of the laser to the human body in the process of using these diversified laser equipment. It is important to know that even if the laser is very simple and convenient, it constitutes us. The damage is irritating and non-recoverable, and can cause blindness in severe cases.</p><p><br></p><p>There are many types of<a href="https://www.laserprotective.com/products" rel="noopener noreferrer" target="_blank"> laser protective glasses</a>, the materials used are opposite, the principles are different, and the application occasions are also opposite. Therefore, to provide ineffective protection against lasers, it is necessary to continue to make reasonable choices for laser protective glasses according to detailed application. When choosing protective glasses, the maximum input power (or energy), beam diameter, pulse time and other parameters of the laser used should be used to determine the maximum laser input radiation or maximum radiation. Then, determine the minimum optical density required by the mirror according to the corresponding span and the maximum allowable radiation (eye-light limit) at the moment of illumination, and select suitable protective glasses based on this. The detailed conditions for the choice are:</p><p><br></p><p>1. The maximum radiation amount Hmax (J / m2) or the maximum radiation degree Emax (W / m2);</p><p><br></p><p>2. Certain protection span;</p><p><br></p><p>3. The required minimum optical density value Dmin at the corresponding protection span;</p><p><br></p><p>4. The asymmetry, asymmetry of protective lenses, the concept effect of incident light, etc;</p><p><br></p><p>5. Resistance to laser radiation;</p><p><br></p><p>6. Visible light transmittance;</p><p><br></p><p>7. Structure and shape.</p><p><br></p><p>The characteristics of laser damage cannot be neglected in the process of using many types of equipment materials, and more importantly, we have always lacked a variety of laser protection equipment, but we do not know how to use lasers. Protection, as long as the laser in Shanghai is now irreversible and irreversible, only know how to use laser protection equipment, I have to say how sad it is. Laser protective glasses hope that we can have a clear understanding of the laser, the speciality and practicality of the laser is indeed very strong, but we can not lose the prevention of the laser.</p>
