Abstract The in vitro optical properties of slices of human brain tissue were measured. The experiments were performed with an integrating sphere and covered the wavelength range from 400 to 1100 nm. Both normal brain tissue (white and grey matter) and tumour tissue (a malignant glioma and a melanotic melanoma) were investigated. From the experimental data the Kubelka-Munk absorption and scattering coefficients were determined. From these data we calculated the transport absorption and scattering coefficients by using the diffusion approximation. Blood and water appeared to be the dominant chromophores. In the wavelength range mentioned, the absorption coefficients varied over more than two orders of magnitude. The scattering coefficients increased slowly towards the shorter wavelengths.
