[Problem] To increase, compared to conventional devices, the range of motion of the light emitter (fixation lamp) in an external fixation lamp for an ophthalmological instrument and allow movement of the light emitter to arbitrary positions. [Solution] The fixation lamp (1) has a first arm (A1), which supports a light emitter (2) and is supported by a second arm (A2) via a first joint (C1), and is configured so that the first arm (A1) is able to revolve around at least two axes of revolution (E1, E2) by means of the first joint (C1) and said axes of rotation (E1, E2) are not disposed on the same line. Thereby, the range in which the light emitter (2) can be moved can be increased compared to conventional devices and the light emitter can be moved to an arbitrary position in an arbitrary direction. |
