ABSTRACT:
An acoustic coupling device for use in a scanning acoustic microscope consists of an acoustic lens which has a concave focusing surface, and an acoustic coupler having a convex surface on which a convergent beam of acoustic radiation is normally incident. The coupler has a coupling surface which conforms to the shape of a test object; the coupler may be disposable. The spacing between the concave and convex surfaces may be varied to give a variable-focus device.
