Slit lamp having a slit illumination system, a binocular microscopic system and a photographing system. The binocular microscopic system has an objective lens assembly which is mounted replaceably on the body. A replaceable lens unit is provided for observation of the endothelial cell of the cornea. The lens unit include an objective lens, a relay lens and mirrors for directing the light bundle through the objective lens to one of the optical paths in the binocular microscopic system.

A device for forwardly and backwardly adjusting a head-rest according to the invention comprises a base plate fixed to stays extending above a back of a seat for an automobile and provided at its ends with lower rails formed with anchoring apertures, a slide formed on its upper surface with guides and on both sides with upper rails to be fitted with the lower rails, a flat plate-like locking lever traversely slidable within the guide of the slide and having a pair of anchoring pieces extending downwardly to engage in the anchoring apertures of the lower rails, a spring for urging the locking lever in one direction, and a cover for covering the base plate and the slide. With this arrangement, the position of the head-rest can be slidably adjusted by pushing the locking lever against the resilient force of the spring, and the head-rest can then be fixed at a desired position by releasing the locking lever.

A slit lamp microscope includes an illumination light source from which light is passed through two separate optical paths to the patient's eye. The first of the optical paths includes a slit mask and a projecting lens so that the light is focused on the patient's eye to provide a bright slit-like illumination. The light which has passed through the second path provides a uniform auxiliary illumination around the illuminated slit area so that the location of the area can be readily determined with respect to other portions of the patient's eye.
