Abstract: An OCT system includes an OCT optical system and a reference attachment. The OCT optical system has a beam splitter for splitting light into a measurement optical path and a reference optical path, a photodetector, a first waveguide, a second waveguide, and first connectors provided at end portions of the first waveguide and the second waveguide respectively for indirectly or directly connecting the first waveguide and the second waveguide. The reference attachment has a third waveguide, and second connectors formed at both ends of the third wave guide and configured to be attachable to and detachable from the first connector, and is attached to and detached from the OCT optical system h attaching and detaching each of the second connectors to and from the first connector to change an optical path length of the reference optical path.

Abstract: A controller of an ophthalmic apparatus finely drives and roughly drives a drive unit of an optometry unit. In a case where a tilt operation of tilting the operation stick within a predetermined range is detected by an operation detection unit, the controller finely drives the drive unit by controlling the drive unit in response to the detected tilt operation, and finely changes a position of the optometry unit. In a case where at least one of a tilt operation of tilting the operation stick over a predetermined range and an operation of a rough movement operation unit is detected by the operation detection unit, the controller roughly drives the drive unit by controlling the drive unit in response to the detected operation, and roughly changes the position of the optometry unit.
