More Information
Summary:A supersonic microscope comprises a container for containing a liquid nitrogen, and an acoustic lens housed in the container to emit a supersonic beam onto the view face of a sample. A volume-variable member is provided in the liquid so that its upper part is extended from the top surface of the liquid. When the observing of the sample, the vertical position of the member is changed for moving the top surface of the liquid nitrogen up and down so that the top surface of the liquid contacts the view face of the sample.
