Abstract
Usually the acoustic field at the back side of a sapphire lens in a scanning acoustic microscope is calculated considering a transducer that is not shifted relative to the optical axis. In a simple model these calculations were modified by taking a parallel shift of the circular transducer into account. With this modified acoustic field at the back side of the lens the V(z) curve for an ideal reflector and for a material which properties are similar to those of aluminium is calculated. These simulations are used for a qualitative analysis of the influence of a transducer shift on V(z) measurement.
