Abstract
The invention relates to a device (5) comprising an optical surface (10) and a cleaning device (15) for cleaning the optical surface comprising:— a wave transducer (25) acoustically coupled with the optical surface and configured to synthesize an ultrasound wave (W) propagating within the optical surface, and— a spraying unit (20) for dispensing a washing liquid (L) onto the optical surface, the device being shaped so that the ultrasound wave displaces the washing liquid on the optical surface.
Claims15
A device comprising:
- an optical surface;
- and
- an apparatus for cleaning the optical surface, the device comprising:
- a wave transducer acoustically coupled to the optical surface and configured to synthesize an ultrasonic wave propagating in the optical surface;
- and
- a spraying unit for delivering a washing liquid onto the optical surface, the spraying unit being superposed on the transducer,
