Sometimes when laser cutting or marking lasers are purchased from overseas it is worth checking they are property certified and compliant for use in the United States or Europe. To be properly compliant with US and European laser safety standards they are required to have the wavelengths they protect against as well as the OD ( Optical Densities ) and L ratings marked on the lenses. The specifications shown on the glasses typically look as below.

More information on selecting laser safety glasses can be found via the below guide. Otherwise feel free to email us at info@dioptika.com on one of our laser safety experts will be happy to help.
