Notes:
The optical absorption spectrum of poly(methyl methacrylate) (PMMA) has been obtained in the wavelength range 570-780 nm via laser calorimetry (employing a dye laser source). Because of the low thermal conductivity of PMMA, the complete solution to the heat conduction equation (carried out numerically) was required in the analysis of the data. At the wavelength of minimum absorption (near 647 nm), the absorption coefficient had the value 153 dB/km.
