The invention relates to a device (5) for cleaning an optical surface (10) having a first optical region of interest (100A) and a second optical region of interest (100B) separated by an intermediate region (200). In the invention, at least one wave transducer (70, 70A, 70B) is acoustically coupled to the optical surface (10) in order to generate a wave that propagates (i) toward and into the first optical region of interest (100A) and (ii) toward and into the second optical region of interest (100B). According to the invention, the cleaning device (5) comprises a single wave transducer (70, 70A, 70B) which simultaneously generates the wave toward and into the two optical regions of interest (100A, 100B) or the cleaning device (5) comprises at least two wave transducers (70, 70A, 70B) which each generate a wave that propagates toward and into a single optical region of interest (100A, 100B).
