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 optical sensor includes a radiation part that irradiates an object to be measured with laser light, an imaging part that receives laser light reflected by the object to be measured and captures an image of the object to be measured, a first driving part that moves the radiation part in a radiation direction of laser light to the object to be measured, and a second driving part that moves the imaging part in a reflection direction of laser light from the object to be measured and an orthogonal direction to the reflection direction.
Abstract:
An optical probe includes a probe cover, within which is installed an optical system having an illuminating optical system and a receiving optical system. An emitting region and an incidence region through which light passes are provided to a bottom surface of the probe cover, the bottom surface forming an opposing region opposite a work piece. The bottom surface forms a surface where, of the light reflected from the work piece, light following a direct reflection direction is reflected in a direction moving away from the incidence region, from a position where light emitted from the emitting region is emitted at the work piece. Accordingly, an amount of second order reflected light striking the incidence region can be suppressed and, therefore, an occurrence of an erroneous value in received light distribution can be suppressed.
