Wherein, the object stage is used to place the component to be tested, the adjusting device 20 is used to adjust the inclination angle of the object stage, and the at least one level is fixed on the object stage. According to the indication result of the at least one level, it is convenient and quick to determine whether the stage is in a horizontal state. If the stage is not in a horizontal state, the inclination angle of the stage can be adjusted by the adjusting device. If it is in a horizontal state, the adjustment is stopped, and the component to be tested can be placed on the stage for subsequent measurement steps.

In a specific example, the at least one level is embedded below the support plane of the stage. Through this structural design, the level can be set without reducing the support area of the stage. It should be noted that the support plane is the plane in which the stage is in contact with the component to be tested.

In one embodiment, the number of level gauges may be only one, as shown in FIG. 2 , that is, only the first level gauge 301 is set on the stage. Preferably, the center of the setting position of the first level 301 overlaps with the center position of the stage (O in FIG. 2 ).
