We have performed high-field optical spectroscopy measurements of the geometrically frustrated chromium spinel oxide CdCr2O4 in the visible light region. We succeeded in observing the pure exciton excitation peak, and identified some other absorption peaks as exciton-magnon excitation peaks from the theoretical calculations of density of states of the spin wave. Furthermore, from the high-field experiment, large variations of absorption peaks were observed at around 4 T. This result indicates that some magnetic phase transition occurs around this field.
