    摘要： White light emitted from a light source is made incident on a spectroscope via a lens. The light from the spectroscope is converged by a lens and fed to one end of an optical fiber. The other end of the fiber is provided with a probe. The probe has a pointed end portion coated with a total reflection film and a transparent electrically conductive film. The probe is attached to a cylindrical piezoelectric actuator via a metal frame. Thus, the probe is scanned along the surface of a sample, and the distance between the probe and the surface of the sample is controlled. The light emitted from the tip of the probe and transmitted through the sample is converged by a lens system and radiated on a photoelectrical conversion element. The output from the photoelectrical conversion element is processed by a signal processor, and the processed result is displayed on a display. A driver circuit scans the probe along the surface of the sample, and controls the distance between the probe and the sample upon receiving a tunnel current. The output from the driver circuit is processed by the signal processor and an STM image is displayed on the display.

    摘要： A scanning tunnel microscope is arranged by a combination of an optical microscope and a tunnel scanning unit. The scanning tunnel unit includes a probe held to be spaced apart from a sample placed on a sample table by a predetermined interval in an axial direction, and an actuator for axially moving the sample table and the probe to a tunnel region and relatively and three-dimensionally driving the sample table and the probe. An objective lens and the probe are arranged such that the axis of the probe of the scanning tunnel unit is aligned with an optical axis of the objective lens of the optical microscope. The sample and the probe are axially moved and brought into the tunnel region, and the sample is scanned in its surface direction while the sample and the probe are finely moved in the axial direction and a tunnel current is kept constant, thereby performing an STM observation of an observation surface of the sample. The objective lens of the optical microscope is axially moved to obtain an in-focus state, and the field of the STM observation surface is observed as an optical microscopic image through an eyepiece lens.

    摘要： A scanning tunneling microscope has an STM unit including a probe for scanning the surface of an object. The STM unit has at its outer peripheral surface a cylindrical enclosing member extending towards an object table. When the object is observed, the object table is elevated or the STM unit is lowered, so that the enclosing member is urged upon the table. The table and the STM unit constitute one body. As a result, relative movement between the object and the probe can be prevented, and also influence due to vibration can be prevented. In addition, the enclosing member isolates the object and the probe from the outside space, whereby electric noise, magnetic noise, sound noise and air flow are shielded. Thus, the influence due to external vibration can be reduced, and the stability is enhanced.

    摘要： A hole is formed in a silicon substrate, passing through the substrate. An insulating film is formed on one face of the silicon substrate and one open end of the hole is thus closed by the insulating film. An antireflection film is attached to that area of the insulating film by which the one open end of the hole is closed. An optical fiber is fitted and fixed in the hole. An optically-transparent conical probe is formed on the area of the insulating film which corresponds to the hole in the silicon substrate and the probe is coated by a metal film while leaving a tip of the probe not coated. A fine aperture is thus formed at the tip of the probe to allow light to enter into the probe through the fine aperture. The metal film prevents light reflected from entering into the probe and light from being leaked from the probe, and it is connected to an electrode to use tunnel current to position the fine aperture near a sample.
