Abstract: A telecentric optical apparatus that is capable of suppressing an increase in the number of components as well as achieving high precision optical axis alignment, is provided. The telecentric optical apparatus of the present invention is characterized in that it is provided with: a first telecentric lens surface that is provided on an object side; a second telecentric lens surface that is provided on an image side and that shares a focus position with the first telecentric lens surface; and an optical path trimming part that is provided, between the first telecentric lens surface and the second telecentric lens surface, in an outside region, which is located on a side further out than a light passing region having a center thereof located at the focus position, and that changes an optical path such that a light beam incident on the outside region is prevented from contributing to image formation.

Abstract: An inclination adjusting mechanism includes a first member that is attachable to a connection portion of a lens unit that is connectable to a lens barrel; a second member that faces the first member and that is attachable to a connection portion of the lens barrel that is connectable to the lens unit; contact members that are fixed to the first member, that protrude from the first member toward the second member, and that contact the second member; and adjusting/fixing members that are capable of adjusting an inclination of the first member relative to the second member and capable of fixing the first member to the second member. The second member has an inclined surface that the contact members contact, and each of the contact members has a curved surface that contacts the inclined surface.

Abstract: A light interference measuring device comprises: a light source 20 that outputs light; a beam splitter 222 that causes the light output from the light source to diverge into a reference optical path and a measurement optical path and that outputs a combined wave in which reflection light that has passed through the reference optical path and reflection light that has passed through a measuring object arranged in the measurement optical path are combined; a reference mirror 231 that is arranged in the reference optical path and that reflects light which is diverged into the reference optical path by the beam splitter 222; a stage 12 that is arranged in the measurement optical path and that has the work W placed thereon; an imaging part 25 that images an image in which the combined wave is formed; a reference mirror adjustment mechanism (234, 238, 239) that adjusts a posture of the reference mirror 231; and a control part that controls the reference mirror adjustment mechanism such that a reflecting surface of the reference mirror 231 corresponds to a measurement surface of the work W, based on an image imaged in a condition where a work W is placed on the stage.
