A bichromatic nondispersive acoustooptic deflector was recently described. A new system, relying on a slightly different principle, is proposed here. It allows simple glass lenses to be used for the chromatic compensation instead of the dispersive crystal-glass compound ones needed in the previous version. Moreover, the new system is tunable for any arbitrary pair of wavelengths. A practical system has been designed and the experimental results agree very closely with the theoretical predictions.
