Tissue transmissivity and absorption coefficients were calculated for components of the refractive media, distilled water, and physiological saline throughout the wavelength interval of 0.2-15 micrometer. All transmission measurements required for these calculations were performed spectrophotometrically using freshly enucleated rhesus monkey eyes and narrow- bandwidth radiation. Much of the absorption coefficient data presented is from wavelength regions where values have not been previously reported.
