Abstract
219,968. Zeiss, C. [Firm of]. Aug. 2, 1923, [Convention date]. Eye-examining apparatus.-An illuminating device for an apparatus for the examination of the eye comprises a source of light f for the illumination of a diaphragm h by the lens system g', g<2>, the whole being carried on a screwed rod d which may be vertically adjusted by the nut c. The lens o for the projection of an image of the diaphragm or the retina is supported in a carrier i mounted on the rod d. The small vertical adjustment necessary for the lens o is effected by the screwed cap r which actuates the screwed rod l supporting the lens o.
