    TEXT VERSION OF SLIDE:

    Title: Table 28-7 - Minimum Optical Densities Required of Protective Eyewea
    Type: Text Slide
    Content:

    TABLE 28-7
    Minimum Optical Densities Required of Protective Eyewear
    (ODmin= log10 H0/MPE or log10 E0/MPE)
    E0/MPE
    or
    H0/MPE
    ODmin
     
    1 = 100 0
    10 = 101 1
    100 = 102 2
    1000 = 103 3
    10000 = 104 4
    100000 = 105 5
    1000000 = 106 6
    Where H0 is equal to the emergent beam radiant exposure in Joules per square centimeter and E0 is equal to the emergent beam irradiance in Watts per square centimeter.
