Scanning head of scanning probe microscope
View Patent ↗A scanning head of a scanning probe microscope includes a scanning head frame having a first end portion and a second end portion which are oppositely disposed, the first end portion and the second end portion defining a first receiving space and a second receiving space, respectively; a sample table located in the first receiving space; a scanning module located in the second receiving space; and a plurality of fixed electrodes fixed on the second end portion of the scanning head frame. Signal lines of the scanning head of the present invention do not fall off or tear off during operation. In addition, the scanning head allows a laser to be incident on its scanning probe, enabling the scanning probe to be coupled with the laser, so that the range of application is wide.

a sample table located in the first receiving space;
a scanning module located in the second receiving space; and
a plurality of fixed electrodes fixed on the second end portion of the scanning head frame.
2. The scanning head of the scanning probe microscope according to claim 1 , further comprising curved wires connected between output terminals of the scanning module and the plurality of fixed electrodes.
3. The scanning head of the scanning probe microscope according to claim 2 , wherein the wires are spiral.
4. The scanning head of the scanning probe microscope according to claim 2 wherein a side wall of the scanning head frame is provided with a light inlet and a light outlet that are oppositely disposed.
5. The scanning head of the scanning probe microscope according to claim 4 , wherein a side wall of the scanning head frame is provided with a sample inlet located between the light inlet and the light outlet.
6. The scanning head of the scanning probe microscope according to claim 5 , further comprising a Pan's stepper motor located in the second receiving space, the Pan's stepper motor includes an adjusting knob, and a side wall of the scanning head frame is provided with an operation through-hole for the adjusting knob of the Pan's stepper motor to extend out.
7. The scanning head of the scanning probe microscope according to claim 6 , wherein the operation through-hole and the sample inlet are located on the same side wall of the scanning head frame.
8. The scanning head of the scanning probe microscope according to claim 6 , wherein the displacement of the Pan's stepper motor for driving the scanning module towards the sample table is less than a maximum extension length of the wires.
9. The scanning head of the scanning probe microscope according to claim 1 , further comprising an electrode limiting member fixed on an end face of the second end portion of the scanning head frame, and the electrode limiting member has a plurality of limiting holes for passing through by a plurality of fixed electrodes.
10. The scanning head of the scanning probe microscope according to claim 1 , wherein the sample table comprises:
a movable sample clamp configured to clamp a sample piece;
a drive device configured to drive the movable sample clamp to move in a plane;
a fixing member connected to the drive device, the fixing member being fixed to the second end portion of the scanning head frame; and
three extraction electrodes fixed on the fixing member.
