Even at lower power output levels, it is possible to cause irreversible ocular injury from a single accidental exposure to a direct or reï¬ected 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 ï¬ltered 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 effectâsimilar to the eï¬ect of sunglasses. Second, blocking certain wavelengths will change our perception of color.
Our laser safety glasses are all certificated by Celab company, the certification number is 802809035823 which can confirmed with Celab company.
