Ultrasonic microscope |
摘要 |
An ultrasonic microscope includes a container for containing a liquid nitrogen, and an acoustic lens housed in the container to emit an ultrasonic beam onto the view face of a sample. A sleeve is located above the container, which has a gas-tight chamber therein communicated with the container and a sample inserting opening formed in the periphery thereof. The sample inserting opening is selectively closed and opened by a gate valve. A sample rod is provided with a sample on its lower end, and may be freely movable up and down in the gas-tight chamber to a position where the sample in the container is scanned and to another position adjacent to the sample inserting opening where the sample is exchanged with a new one.
