  • Publication number: 20020088919
    Abstract: According to the conventional light detection of a light probe microscope, there have been a problem that an excessive stray light is detected in case that a detector whose light-intercepting face is large with respect to the size of a bright point is used, and a problem that an optical axis alignment is necessary in case that the detector having a small light-intercepting face in the order of the bright point is used. Besides, in order to obtain plural optical information, plural light detectors have been necessary. It is adapted such that, by using a two-dimensional image sensor, a two-dimensional image is obtained in real time, and a signal intensity of an optional detection region in the two-dimensional image is obtained by picture signal processing means. It is adapted such that plural information are image-formed on the two-dimensional image sensor, and plural detection regions are designated.

  • Patent number: 6280647
    Abstract: In a method for sharpening a probe, a probe preform having a longitudinal axis is at least partially immersed in a mixture containing at least an etch solution and a non-etch solution having a lower specific gravity than and which is not miscible with the etch solution. The probe preform is moved in the mixture along the longitudinal axis thereof during etching at a speed which does not exceed a taper length forming speed for a probe preform which is not moved in the etch solution during etching. An end of the probe preform is etched into a sharp tapered tip having a taper angle greater than that obtained for the probe preform which is not moved during etching.

  • Patent number: 6249000
    Abstract: A scanning probe microscope comprises a cantilever probe disposable proximate a surface of a sample and having a first resonance frequency. A three-dimensional fine movement element scans the cantilever probe and the surface of the sample relative to one another two-dimensionally. A sensor cantilever detects displacement of the cantilever probe during relative scanning movement between the cantilever probe and the surface of the sample. The sensor cantilever has a second resonance frequency different from the first resonance frequency and is disposed spaced apart but within touching distance from the cantilever probe so that displacement of the cantilever probe is transmitted to the sensor cantilever by contact between the sensor cantilever and the cantilever probe.
