Abstract

The data reported in journals on angle resolved scatter measurements for highly transparent window materials is scarce. An experimental facility with enough sensitivity to measure such low level scatter is described. A dynamic range of at least eight orders of magnitude is required to measure the peak of the specular component down to the random diffuse component far removed from the specular direction. Single crystal CaF₂ and polycrystalline CVD ZnSe are measured at wavelengths from the visible to the midwave infrared. The use of thick and thin samples allows the distinction between surface scatterance and bulk scatter.
