Abstract: A mounting mechanism of a lens unit includes a first mounting mechanism that includes a first mounting portion mountable on a telescope cylinder or the lens unit and a guide groove portion extending in an insertion direction intersecting with an optical axis direction, a second mounting mechanism including a second mounting portion mountable on the telescope cylinder or the lens unit and a guide protrusion portion configured to be housed in the guide groove portion and has a configuration at least a part of which is configured to be insertable into the first mounting mechanism along the insertion direction, and a positioning unit that performs a positioning of the telescope cylinder and the lens unit in the insertion direction in a state where the second mounting mechanism is inserted to a predetermined position with respect to the first mounting mechanism.

Abstract: An image measurement apparatus includes an image pickup unit, a mounting unit, and a judgment unit. The image pickup unit captures a measurement target. The measurement target is mounted on the mounting unit, the mounting unit being capable of moving relative to the image pickup unit. The judgment unit judges, based on information related to a relative position between the image pickup unit and the mounting unit within a predetermined time, whether capturing of a measurement image by the image pickup unit is possible.

Abstract: Provided is a chromatic confocal sensor including: a first light source that emits measurement light including a plurality of light beams having different wavelengths; a second light source that emits a visible light beam having a predetermined wavelength; an optical head that causes incident light to be converged at a focal position corresponding to a wavelength of the incident light and outputs reflection light reflected by an object to be measured at the focal position; a position calculation section that calculates a position of the object to be measured on the basis of the reflection light output by the optical head; and a switching section that selectively switches between a first operation in which only the measurement light enters the optical head and a second operation in which at least the visible light beam enters the optical head.

Abstract: A light source apparatus includes a light source, an optical fiber, and a positioning mechanism. The positioning mechanism is configured with a planar position adjustment mechanism, an axial line position adjustment mechanism, and an orientation maintaining mechanism. The planar position adjustment mechanism adjusts a position of the optical fiber in a direction following the light-emitting surface. The axial line position adjustment mechanism adjusts the position of the optical fiber in a direction intersecting with the light-emitting surface. The orientation maintaining mechanism holds the optical fiber in a state where an axis direction of the optical fiber lies in a predetermined intersecting direction with respect to the light-emitting surface.
