A microscopic area scanning apparatus is provided with at least three hollow cylindrical piezoelectric elements each driven in three XYZ directions by one of divided electrodes. Three or more hollow cylindrical piezoelectric elements are arranged on a circumference of a common plane. Balls are each axially provided at a free end of the hollow cylindrical piezoelectric element. Ball retainers rotatably and slidably support a respective ball in contact therewith. A sample stage is fixed to the ball retainers. A table fixes the hollow cylindrical piezoelectric elements on the circumference of the common plane. Thus, the microscopic area scanning apparatus can realize both a wide X-Y scanning range and a high Z-direction resonant frequency without utilizing an elastic hinge.

A self-emitting optical probe having a built-in light-emitting function, wherein the light-emitting mechanism and the aperture portion of the optical probe are formed by depositing an electrically conductive thin film, an organic thin film, and a metallic film by means of sputtering and oblique vacuum evaporation while rotating the core. The self-emitting optical probe enables an inexpensive scanning near field optical microscope yet simplified in operation.

A scanning near-field optic/atomic-force microscope comprises a holder for holding a sample immersed in a liquid, and a plate disposed over the holder for covering a surface of the liquid and for transmitting therethrough a laser light. A probe has an optical propagation body terminating in a distal end, and a light reflecting element disposed thereon, and the probe is immersed in the liquid. A light source emits a light which is introduced into the optical propagation body of the probe, which guides the light through the probe and out the distal end thereof to irradiate the sample. A detecting device detects information from the light irradiated on the sample and converts the information to an electric signal. A laser source irradiates the light reflecting element of the probe with a laser light for detecting a bending amount of the probe resulting from an interaction between the sample and the probe. An angle adjusting mechanism adjusts an optical axis of the laser light transmitted through the plate. A photoelectric conversion device receives the laser light reflected from the light reflecting element and converts the reflected light into an electric signal. A moving mechanism moves the sample relative to the probe, and a distance control device controls a distance between the surface of the sample and the distal end of the probe.

A proximity field optical microscope is provided which can simultaneously conduct optical observation in the ultraviolet and infrared light ranges and conduct geometrical observation and detect other physical information, wherein a microscopic opening is stably and easily formed in a probe tip with low manufacturing cost and high yield. The microscope has an optical probe which comprises a tube having a tip portion formed with a smaller diameter than an overall diameter of the tube, an optically opaque material coated on the tube, an optical microscope opening formed at the tip portion, and an optical waveguide having at least two optical end surfaces, one end surface being inserted in the tube facing the microscopic opening.

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.

An easy to use scanning probe instrument such as a microscope or memory device is provided with a probe which does not require optical alignment. The scanning probe is a cantilever probe adapted to undergo relative movement with respect to an object such as a sample or a recording media. Optical interference and/or displacement of the cantilever probe caused by interaction with the object while the probe is being scanned across the object is measured to determine characteristics of the object. The cantilever probe has a base member, a cantilever formed in the base member, at least a portion of the cantilever being elastically deflectable to enable the cantilever to be displaced in a given direction. A waveguide extends through the base member and has one end surface disposed proximate the cantilever, the one end surface being positioned perpendicularly with respect to the given direction of displacement of the cantilever and being spaced from the cantilever by a distance sufficient to allow displacement of the cantilever by a desired amount in the given direction.

Adjustments during assembly of an illuminating unit having a conventional light pipe in order to position the light pipe and a light guide plate are laborious. Further, a minute prism group having a pitch on the order of 100 μm must be provided to a side surface of the light pipe in order to uniformly guide illuminating light to the light guide plate. An illuminating unit of the present invention is provided with a light guide plate having an illuminating surface that is illuminated by light from a point light source, and a light pipe having an incident surface to which light from the point light source is made incident and an emerging portion from which the light emerges to the light guide plate. The emerging portion and the light guide plate are integrally joined.

A lighting device includes a light guide plate and a point light source located on a light incident surface side of the light guide plate. Micro-structures for light-scattering are provided separate from one another on a surface opposed to the light exit surface of the light guide plate. Each of the micro-structures for light-scattering has an orientation in a longitudinal direction. The longitudinal direction becomes substantially parallel to a direction joining the micro-structure for light-scattering with the point light source. With this structure, a high intensity of the lighting device is realized. The surface opposed to the light exit surface of the light guide plate is divided into a plurality of regions. A thickness of the light guide plate reduces stepwise in the respective regions as a distance from the point light source increases.
