Optical-optical double resonance spectroscopy has been applied to measure the hyperfine structure of spectral line pairs of atomic osmium in the visible wavelength range. In the experiments, enriched isotope samples of either Os-189 or Os-187 were used. In this way, the magnetic dipole hyperfine interaction constants A of the odd isotope Os-187 were determined for seven levels of even parity and two levels of odd parity.
