Product Description

Why Laser Safety? Even at lower power output levels, it is possible to cause irreversible ocular injury from a single accidental exposure to a direct or reflected laser beam, depending on the wavelength, output and exposure duration. Laser safety can prevent damage to equipment as well. An important factor in determining damage potential is irradiance, the power per area, expressed in watt/cm2. Daylight Transmission (VLT) and Color Vision When we wear laser safety glasses, some wavelengths of the spectrum that would normally reach our eyes are filtered out. If we block light from the visible region, this inevitably changes our perception of our environment. First, the attenuation of transmission in the environment increases, causing a darkening effect—similar to the effect of sunglasses. Second, blocking certain wavelengths will change our perception of color. Professional and Certified Our laser safety glasses are all certificated by Celab company, the certification number is 802809035823 which can confirmed with Celab company. The valid date is from Mar 30, 2020 to Mar 19, 2024. High Quality Filters FreeMascot offers advanced collection of polymer or polycarbonate laser safety eyewear filters. We employ leading material science at our production facilities to consistently manufacture the most advanced laser absorbers and coatings. Our development efforts have resulted in a complete line of polycarbonate laser eyewear. Multi Frames to Select We offer a variety of standard and fit-over frames to accommodate your specific needs. Our frames are built for comfort and protection. All are made to fit multiple filters. Safe Packing Each pair of safety glasses comes with a protective storage case and a cleaning cloth.
