This European Standard applies to laser adjustment filters and eye-protectors. These are filters and eye-protectors for use in adjustment work on lasers and laser systems as defined in EN 60825-1:2007 where hazardous radiation occurs in the visible spectral range of 400 nm to 700 nm. Filters specified in this European Standard reduce this radiation to values defined for lasers of class 2 (= 1 mW for CW (continuous wave) lasers). This European Standard defines the requirements, test methods and marking. A guide is given in Annex B with regard to selection and use. EN 207 applies to eye-protection against accidental exposure to laser radiation. NOTE Before selecting eye protection according to this European Standard a risk assessment should first be undertaken (see Annex B).
