        We all know the trust of laser protective glasses has widely applicability, about our eyes who played a good protective effect, so let more people understand that we can get the laser protective glasses, consumer recognition, laser protective glasses for the crowd: laser operators, computer operator, driver, gas welder, welders, high-temperature furnace operation personnel, medical personnel or industrial operation, laser protective glasses below small to take us to choose suitable.
        There are many types of laser protective glasses, the information is not the same, different principles, applications are not the same. Therefore, in order to provide useful protection to the laser, the laser protective glasses must be selected reasonably according to the detailed requirements. Choose the door mirror, according to the maximum output power of the laser (or energy), beam diameter, laser pulse time parameters determine the maximum output irradiance or maximum exposure. Then, according to the maximum amount of the corresponding wavelength and light irradiation to time (eye shine limit) concluded that glasses the minimum optical density value, and select the appropriate protective glasses.
       The detailed conditions of selection are:
        1, the maximum amount of radiation Hmax (J/m2) Emax (W/m2) or the maximum irradiance;
        2, specific protection wavelength;
        3, the optical density value of Dmin to the corresponding protective wavelength;
        4, the protective lens non-uniformity, asymmetry, the effect of the incident light point of view;
        5, anti laser radiation ability;
        6, visible light transmittance;
        7, structure and shape.
        Laser protective glasses, laser protective glasses, laser glasses, laser protection, protective glasses we only have one pair of eyes, please pay attention to the protection!
        U.S. laser safety code ANSI Z136.1ANSI Z136.1 specification: after optical density (OD, Optical Density) to measure. The logical relationship between optical density OD and transmittance T: D=-log10 T. European laser safety code EN207/EN208EN207/EN208 specification: consider the optical density of OD, but also need to consider the damage threshold (power / energy density changes with time).
        Laser protective glasses suitable for the shelter of ultraviolet laser, excimer laser, Nd: glass laser, semiconductor laser, CO laser, Nd: YAG laser, ruby laser, CO2 laser, laser and other GaAs lasers, made excellent protection for the eyes, let the touch of these work we can in the time of laser protective glasses we use the acceptance of our products. Everyone wants a good commodity, so our products are worthy of our trust.
