Abstract: An OCT device that selectively captures OCT data of a fundus of a subject eye and OCT data of an anterior segment of the subject eye. The OCT device includes a spectroscopic optical system that spectroscopically detects interference light between reference light and reflection light of measurement light irradiated on the subject eye. The spectroscopic optical system includes a collimating system that collimates the interference light, a spectrally dispersive element that spectrally disperses the collimated interference light for each spectral wavelength, an image formation system that forms an image of the interference light for each spectral wavelength on an imaging surface, and a light receiving element disposed on the imaging surface. An object-side focal length of the collimating system is shorter than an image-side focal length of the image formation system.

Abstract: An ophthalmologic apparatus that inspects a subject eye of a subject. The ophthalmologic apparatus includes an optometry device for inspecting the subject eye, a base for supporting the optometry device, an face supporter for holding the subject eye at an optometry position by supporting a face of the subject, and a changing device for relatively changing a positional relationship between the optometry position and the base in a working distance direction of the optometry device.

Abstract: A technical object is to provide an ophthalmic apparatus and an ophthalmic apparatus control program that are capable of appropriately performing alignment in a wide range. An ophthalmic apparatus that examines an examinee's eye includes: an optometry unit that examines the examinee's eye; drive means that adjusts a relative position between the optometry unit and the examinee's eye; an illuminating optical system including a first illuminating optical system for illuminating an anterior segment of the examinee's eye and a second illuminating optical system for illuminating a wider range than the first illuminating optical system; an imaging optical system including a first imaging optical system for imaging the anterior segment of the examinee's eye and a second imaging optical system for imaging a wider range than the first imaging optical system; and control means that controls an illuminating state with respect to the anterior segment between anterior segment illumination by the first illuminating optical system and wide range illumination by the second illuminating optical system.

Abstract: An ophthalmic apparatus for examining an examinee's eye, comprising a face support member to support an examinee's face, a human detection member to detect whether or not the face is supported by the face support member, a notification member to give an announcement to an examinee or an examiner, and a control member to control the notification member based on a detection result of the human detection member.
