Abstract

The present disclosure provides a device comprising a transducer with adjustable focus. In some examples, the device comprises an acoustic transducer configured to provide an acoustic beam. The device may further comprise a lens mount acoustically coupled to the acoustic transducer. The lens mount may comprise a gap configured to contain a coupling fluid. The lens mount may be configured to receive the acoustic beam from the acoustic transducer. The device may further comprise a focusing lens acoustically coupled to the lens mount. The focusing lens may be configured to receive the acoustic beam from the lens mount. The focusing lens may be configured to focus the acoustic beam to the biological sample when the biological sample is in acoustic communication with the focusing lens.
