ABSTRACT:
This application discloses an ophthalmoscope illumination arrangement including a bulb mounted in a special bulb carrier which is adapted to cooperate with the ophthalmoscope chassis so as to automatically position the bulb for best illumination. The bulb carrier and ophthalmoscope chassis cooperate to establish the longitudinal position of the bulb filament along the illumination axis of the instrument and to align the rotational position of the bulb filament with the upper edge of the reflective mirror or prism so that the illumination beam is in close alignment with the viewing axis of the instrument.
