PROBLEM TO BE SOLVED: To enable a measured object to be checked after measurement.SOLUTION: An intermediate adaptor 10 comprises: a casing body 101 that is attachably/detachably inserted between an interchangeable lens 20 of an interchangeable type camera and a camera body 30, and has a predetermined width in an optical axis direction of the interchangeable lens 20; splitting means 103 that is provided inside the casing body 101, splits a beam of light having passed through the interchangeable lens 20 into two directions, guides one beam of light to imaging means 302 within the camera body 30, and guides the other beam of light to measurement means 105 which optically measures the beam of light; and a compensation optical system 104 in which an increase in an optical path length of the beam of light that is caused by insertion of the casing body 101 is compensated so as to form an image generated by the beam of light heading for the camera body 30 from the interchangeable lens 20 on an imaging plane of the imaging means 302, and also the beam of light having passed through the interchangeable lens 20 passes through the division means 103, thereby correcting a generated optical aberration. |
