Problems solved by technology

[0004] Existing scanning probe microscopes correspond to different use modes, such as: atomic force microscope mode, scanning tunneling microscope mode, etc., and have different probe holders. It is not easy to make adjustments to the circuit structure and probe clamping method when conducting scientific research experiments. Change; it is suitable for the probe holder of atomic force microscope and other modes, which presses the probe on the metal block through the elastic sheet, without precise positioning and clamping structure, and the laser spot at the end of the probe cantilever moves every time the probe is replaced. position, the laser optical path needs to be readjusted, which complicates the operation, and after changing the probe, the sample scanning area will change in a large range, which is not conducive to repeated observation; when changing the probe, it is necessary to manually lift the unfixed end of the elastic sheet or loosen it. The screws fixing the elastic sheet are inconvenient to operate, and the elastic sheet is manually lifted for a long time, and the force on the end is uneven, which will cause asymmetric deformation of the elastic sheet, affect the clamping effect of the probe, and then affect the test quality

The probe holder for the modular scanning probe microscope of the present invention has the advantages of simple operation, good clamping effect, precise probe positioning, improved testing accuracy and testing efficiency, and low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of scanning probe testing, in particular to a probe frame for a modular scanning probe microscope. Background technique [0002] Scanning probe microscope is a general term for a group of microscopes that use probes to mechanically scan the surface of the sample to obtain sample information, including scanning tunneling microscopes, atomic force microscopes, magnetic force microscopes, friction force microscopes, scanning near-field optical microscopes, static Electric Power Microscope, Magnetic Resonance Force Microscope, Scanning Capacitance Microscope, Scanning Hall Effect Microscope, etc. Among them, scanning tunneling microscope and atomic force microscope are the most commonly used. Scanning tunneling microscope is the first scanning probe microscope invented by IBM's G.Binning and H.Rohrer in 1982. It uses the quantum tunneling effect to obtain the information of the sample surface by detecting the t...
