摘要： A CCD camera (27) images a work to generate its image data. An imaging optical system (24, 25, 26) focuses an image of the work on the CCD camera (27). A down-projection illumination source (31) includes at least one semiconductor light-emitting device for producing a down-projection illumination light to illuminate the work from above. An illuminating optical system (29) joins the illumination light from the down-projection illumination source (31) to the imaging optical system in order to lead the illumination light to the work via the imaging optical system. These optical components are mounted on a chassis (23) to construct an imaging probe (1), which is employed at any angle as a measuring probe of a three-dimensional tester.

摘要： A plurality of light emitting elements comprise a number of groups having light emitting colors different from each other. The light emitting element groups are arranged in ring shapes about an optical axis of an optical system in a plane or planes substantially orthogonal to the optical axis. A combining unit combines radiation light beams of different light emitting colors to generate illumination light having a given hue. The combining unit is provided downstream of the light emitting elements along a light emitting direction. A focusing unit focuses the illumination light in the direction toward the optical axis and is provided downstream of the combining unit. Accordingly, it is possible to direct illumination light having uniform and non-irregular hue, the hue corresponding to a surface color of an object to be measured, to the object to be measured.

摘要： A light source (110) is fixed at a position and emits light in a direction away from an optical axis (A) of an objective lens. An outer reflecting mirror (an optical member) (130) and an inner reflecting mirror (an optical member) (140) are provided as a unit so that relative positions thereof are fixed. A reflecting mirror unit (120) can be moved in directions along the optical axis (A), i.e. up and down relative to the light source (110). A free-form curved surface portion (131) of the outer reflecting mirror (130) and a reflecting surface of the inner reflecting mirror (140) reflect light in different directions depending on a position of the light incident thereon.
