Description

Technical Field

[0001] The utility model relates to the technical field of sample installation, in particular to a sample loading device. Background Art

[0002] The transmission electron microscope is a high-resolution microscope that is often used to observe the microstructure of materials. When observing samples, the transmission electron microscope generally uses a stage to complete the sample loading operation. Specifically, the sample to be observed is cut into thin slices and fixed on the stage. Then the stage with the sample is inserted into the sample chamber of the microscope, and then the position of the stage is adjusted in combination with the objective lens to obtain a clear image.

[0003] The existing loading device (stage) usually includes a supporting table, on which a clamping structure is arranged to fix the slide. The clamping structure is usually an elastic pressure sheet or transparent tape: an adjustment mechanism is arranged under the supporting table, and the plane position of the sample is adjusted by adjusting the position of the supporting table, so that the sample is adjusted to a position where a clear image can be loaded. The adjustment mechanism is generally a gear rack or a screw structure.

[0004] However, the existing stage still has the following shortcomings during use:

[0005] When actually using a transmission electron microscope, in order to fully understand the microstructure of the sample, it is sometimes necessary to observe the sample at different angles. However, the existing stage can generally only adjust the position of the sample by translation within the plane and rotate the angle of the sample. Therefore, when the tilt angle of the sample needs to be changed, the inspector may be required to perform secondary or even multiple installation processes such as raising the corners of the slide. This method is cumbersome to operate, cannot achieve continuous adjustment, and has low flexibility. Utility Model Content
