Summary: | An ultrasonic microscope apparatus using cryogenic fluid as an ultarsonic propagating medium including a top loading space, in which specimen can be exchanged as the space kept airtight, and x-, y- and z-direction adjusting devices by means of which the relative position and the distance between the specimen and an acoustic lens can be adjusted under an airtight condition. The ultrasonic microscope apparatus also includes a vapor pressure adjusting device for adjusting the vapor pressure within a heat insulated vessel, in which the cryogenic fluid is contained, to prevent the cryogenic fluid from boiling. |
