ABSTRACT:
This low temperature ultrasonic microscope comprises an adiabatic container having an opening in the upper part and containing a low temperature liquid which is an ultrasonic wave transmitting medium, a sample supporting member supporting a sample to be observed, removably inserted into the adiabatic container through the opening and arranged at the upper end out of the adiabatic container, an ultrasonic wave image observing device which has an acoustic lens arranged within the adiabatic container and projecting an ultrasonic wave beam toward the sample, the above mentioned device detecting sound waves projected from the acoustic lens and disturbed by the sample and obtaining an ultrasonic wave image, a housing part housing the upper end part of the sample supporting member and a connecting member which can connect through a path the housing part and adiabatic container with each other.
