340 laser safety glasses were primarily developed for protection from laser wavelengths 950-10,600 nm: Diode, Fiber Optic Diodes, Nd:YAG, Er:YAG, Ho:YAG, CO2 (980 nm, 1,064 nm, 2,780 nm, 2,940 nm, 2100 nm, 10,600 nm). This laser eyewear may provide protection from other laser wavelengths not listed. Please see specifications for additional information about the frame and the filter, or contact us. Filter specifications are permanently engraved. These laser safety glasses meet and/or exceed US ANSI Z136 standards for use with lasers.
These laser safety glasses meet and/or exceed US ANSI Z136 standards for use with the appropriate laser systems.

Optical Density: is a measure of the transmittance of an optical element for a given length at a given wavelength λ. The higher the optical density, the lower the transmittance of light at a specified waveleng. See the ANSI Z136 for more information about OD and laser glasses.

VLT: The attenuation of light by a filter in the visible spectrum. VLT is determined in relation to standard illumination and evaluated according to the daylight-adapted (photopic) or night-adapted (scotopic) conditions descriped more in the ANSI Z136.7 for Testing and Labeling of Laser Protective Equipment. The lower the VLT, the less "visible" light is transmitted. Laser glasses may affect the ability to see warning lights/signs or distinguis between colors.
View Through Laser Glasses Filter*:
*View Threw Laser Glasses Filter is a general representation of the visibility through the laser glasses. The color and transmitted light may vary from what is shown. Please contact us for more information about this laser filter and appropriate viewing conditions was well as wavelengths that may not be visible because of these laser glasses.
LSOs (Laser Safety Officer) need to consider working environments, viewing conditions and beam delivery systems when making assessments and determining the correct laser glasses or goggles to protect against potentially hazardous laser light. Do not opperate lasers without correct protective laser glasses, laser goggles, and laser safety training.
