Laser Goggles Od Rating

The lb number is the scale defined in the standard en 207 2009.

Laser goggles od rating.

For example glasses with od 2 reduce the laser beam by a factor of 100 10 to the 2nd power. The lb rating calculation defines the minimum markings required on the laser safety glasses to ensure protection from the specified laser at the target distance selected. Has emerged as a leader in the eye safety industry by maintaining a singular focus. The lg14 laser safety glasses have an alignment rating of 1 w 2 x 10 4 j 532 rb3.

Has emerged as a leader in the eye safety industry by maintaining a singular focus. When shopping for laser glasses know the terminology and you ll have a good idea of what the protection rating on your glasses really means. They classify glasses and goggles by its optical density od. At 532 nm the glasses will have an optical density between 3 and 4 correlating to transmission between 0 1 and 0 01.

That is the base 0 logarithm of the attenuation factor by how much the filter reduces the beam s power. Optical density and wavelength work together in laser protection to indicate the amount of protection you get from a given laser. The lg14 laser safety glasses have an alignment rating of 1 w 2 x 10 4 j 532 rb3. If you are having trouble knowing the appropriate optical density needed for your glasses or laser safety protection please give us all call at 1 888 752 7370 or 952 405 6947.

When buying laser safety glasses and goggles be sure to select the laser glasses to block or attenuate the appropriate wavelength range and optical density od.
