Abstract
Optical absorption in polystyrene and poly(methyl methacrylate) was measured in the visible region of radiation. Two methods of data evaluation yield consistent results to indicate that near λ=500 nm, the absorption coefficient is approximately 2×10−4 cm−1, or less than 100 dB/km, for both materials.Keywords
