Slit Lamps - 4 Models
The slit lamp is essentially a simple and generally under-used piece of equipment. It consists of an illumination system and a binocular observation system, which when correctly aligned will result in a coincidental focus of the slit and microscope.

Illumination system
Basically a short focus projector projecting an image of the illuminated slit aperture on to the eye. This part of the system should be flexible to allow various sizes and shape of slit beam. Usually a rheostat is incorporated and the lamp house can be rotated. Neutral density, cobalt blue and red free filters are usually available, and occasionally a diffuser and polarizer

Using the slit lamp
Commence the examination using the 10x eyepieces and the lower powered objective i.e. 1x. Use the lowest voltage setting on the transformer. Select the longest slit length by means of the appropriate lever (17). Adjust the chin rest by means of control 27 so that the patient's eyes are approximately level with the black marker on the side of the head rest. Adjust the height of the slit lamp until the slit beam is centred vertically on the patient's eye. Focus the slit beam on the eye by moving the joystick (1) either towards or away from the patient. Coarse positioning can be effected without using the microscope but critical focussing should be carried out whilst viewing through the microscope. The slit width is varied by rotating either the left hand or right hand knurled control 10. To vary the angle between illumination and microscope use one or other of these same controls as handles.
