    Abstract: A shape measuring apparatus includes a first light source, a second light source, an optical system, an image capturer, and a controller. The first light source emits visible light. The second light source emits measurement light used in a measurement. The optical system emits the visible light and the measurement light at the same position on a work piece. The image capturer captures an image of the measurement light reflected by the work piece. The controller is configured to cause the emission of the visible light onto the work piece with the first light source when determining a measurement position, and to control the emission of the measurement light onto the work piece with the second light source when making the measurement.

    Abstract: An optical device includes a first lens holder holding a collimating lens, a second connector block supporting the first lens holder, a second lens holder supporting a light-forming lens, a pillar-shaped roller interposed between the second connector block and the second lens holder and disposed along an X-axis direction, and a pair of adjuster screws disposed across an optical axis in a Y-axis direction, the second lens holder and the second connector block being fixed with each other by the adjuster screws. Mutually facing end faces of the second connector block and the second lens holder are provided with respective V-shaped grooves extending along the X-axis direction, the roller being interposed between the V-shaped grooves. Each of the adjuster screws includes a head engaged with the second lens holder in a manner capable of relative movement in the X-axis direction and a shaft screwed into the second connector block.

    Abstract: An illumination apparatus according to the present invention includes a light source, a reflecting mirror, an optical system, and a calculator. The reflecting mirror includes a first reflector and a second reflector, and is capable, while changing a reflection angle, of reflecting and directing at an object a first divided light, the first divided light being a portion of light from the light source emitted at the first reflector. The optical system divides the light from the light source into the first divided light and a second divided light, and guides the second divided light to the second reflector. The calculator is capable of calculating the reflection angle of the reflecting mirror by receiving the second divided light reflected by the second reflector.
