  • Patent number: 11454647
    Abstract: A cantilever has a probe at a tip end. An optical system emits laser light to the cantilever and detects the laser light reflected by the cantilever. A measurement unit measures characteristics of a sample based on a displacement of the cantilever obtained by a change in a position of the laser light detected by the optical system. The laser light adjustment unit adjusts, when adjusting the optical axis of the laser light, a spot diameter of the laser light to be larger than the spot diameter when measuring the characteristics of a sample. The imaging unit captures an image of a range including the position of the probe when adjusting the optical axis of the laser light. The display unit displays the captured image.

  • Patent number: 10641790
    Abstract: Provided is a scanning probe microscope being able to shorten an observation time of a minute observation object. Main measurement is performed to acquire a surface image of a sample based on a detection signal in a measurement range of a plurality of lines by repeating, for each line, processing of scanning a cantilever at predetermined second intervals in a Y-direction after acquiring the detection signal at predetermined first intervals while scanning the cantilever on a line having a predetermined length along an X-direction. Preliminary measurement is performed to acquire a surface image of the sample by acquiring the detection signal at intervals wider than the first intervals or scanning the cantilever in the Y-direction at intervals wider than the second intervals before the main measurement, the surface image of the sample being coarser than the surface image in the main measurement.
