How important is choosing the right laser protective

by:LASERRPAIR     2020-06-20
???I believe we all know that laser protective glasses have a great scope of application, and it has an excellent protective effect for our eyes, so let more people know that our laser protective glasses can be recognized by consumers. Applicable people for protective glasses: laser operators, computer operators, drivers, gas welders, electric welders, high-temperature furnace operators, medical or industrial personnel. The following editors take us to select suitable laser protective glasses. There are many types of laser protective glasses, with different materials, different principles, and different applications. Therefore, to provide useful protection to the laser, the laser protective glasses must be properly selected according to the detailed use request. When choosing protective glasses, first determine the maximum irradiance or maximum irradiance of the laser output based on the maximum output power (or energy), beam diameter, pulse time and other parameters of the laser used. Then, according to the corresponding wavelength and the maximum allowable irradiation at the moment of irradiation (eye irradiation limit), determine the minimum optical density required for the glasses, and select suitable protective glasses accordingly. ? ?The detailed conditions for selection are: ???1. Maximum irradiance Hmax (J / m2) or maximum irradiance Emax (W / m2); ???2. Specific protection wavelength; ???3. The required minimum optical density value Dmin at the corresponding protection wavelength; ???4. Non-uniformity, asymmetry of protective lens, viewpoint effect of incident light, etc .; ???5. Ability to resist laser radiation; ???6. Visible light transmittance; ???7. Structure and appearance. ???Laser protective glasses, laser protective glasses, laser glasses, laser protection, protective glasses, we only have a pair of eyes, please pay attention to protection! Laser specifications and classification ???American laser safety specification ANSI Z136.1 ANSI Z136.1 specification: measured by optical density (OD, Optical Density). The logical relationship between optical density OD and transmittance T: D = -log10 T. European laser safety standard EN207 / EN208EN207 / EN208 specifications: thinking about optical density OD, in addition to the damage threshold (power / energy density changes with time). Laser protective glasses are suitable for the protection of various lasers such as ultraviolet laser, excimer laser, neodymium glass laser, semiconductor laser, CO laser, neodymium-doped garnet laser, ruby ??laser, CO2 laser, gallium arsenide laser, etc. Good protection, so that those who have touched these jobs can recognize our products when using our laser protective glasses. Everyone wants good products, so our products are worthy of our trust.
