Abstract
A coupler for use between an ultrasonic transducer probe and a sample to be examined thereby to keep the ultrasonic transducer probe and the sample spaced a prescribed distance from each other includes an acoustic lens in an area through which a ultrasonic signal is to pass from the ultrasonic transducer probe. The acoustic lens allows the focusing point of the lens of the ultrasonic transducer probe to be shifted to a desired position. Since the ultrasonic transducer probe and the sample are spaced from each other by the coupler, the image of an observed region of the sample can be positioned in a wide field of view on a screen.
