ABSTRACT:
A device for focussing or collimating a beam of acoustic radiation comprises a body of acoustically transmissive material having first endface (12) coupled to a source of acoustic radiation (16, 18). The radiation is internally reflected by the side surface 20 of the body, this surface being of a shape such that it brings the radiation to a focus F after transmission through a second surface (14).
