Using the apparatus and methods previously reported by the author1), 2), reflection characteristics of several kinds of ground glass, prepared by rubbing with alundum of 100 to 300 mesh, are measured. The results obtained are as follows:
1. The distribution of the relative area of mirror facets having various inclination to the mean surface resembles normal distribution, but the kurtosis index is somewhat larger.
2. When the incidence or reflecting angle is larger than 50°, the maskings of mirror facets occur and the coarser the roughness of the surface, the larger the magnitude of the maskings.
3. If the distribution of mirror facets is represented by the normal distribution function having the standard deviation of about 18° and the masking of them by the exponential function, the reflection characteristics of ground glass can be approximately explained by the combination of these two functions.
