Abstract

A method is presented to evaluate optical absorption at a random wavelength by calculating temperature distribution in single-layer Ti O 2 films. Temperature distribution in single-layer Ti O 2 films was analyzed based on temperature field theory. Through our calculations, optical absorption variation was obtained to be similar to that of surface temperature rise in films. The surface temperature rise depends on film thickness, refractive index, extinction coefficient, specific heat, and thermal conductivity. Furthermore, the optical absorptions of the same single-layer Ti O 2 film at different wavelengths were deduced. As an example, the surface temperature rises were calculated for the 19 single-layer Ti O 2 films, which had been prepared by 12 different laboratories for the annual meeting of the Optical Society of America in 1986. The results agree well with the measured optical absorptions.
