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

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

Using the slit lamp
Commence the examination using the 10x eyepieces and the lower poweredobjective i.e. 1x. Use the lowest voltage setting on the transformer. Selectthe longest slit length by means of the appropriate lever (17). Adjust the chinrest by means of control 27 so that the patients eyes are approximately levelwith the black marker on the side of the head rest. Adjust the height of theslit lamp until the slit beam is centred vertically on the patients eye. Focusthe slit beam on the eye by moving the joystick (1) either towards or away fromthe patient. Coarse positioning can be effected without using the microscopebut critical focussing should be carried out whilst viewing through themicroscope. The slit width is varied by rotating either the left hand or righthand knurled control 10. To vary the angle between illumination and microscopeuse one or other of these same controls as handles.

The slit should be set primarily in the vertical position, butany desired inclination can be achieved by means of the ball handle 15 (notchesat 45, 90, 135; stops at 0 and 180). By tripping the latch 11 and tiltingthe slit lamp column, the beam can be introduced from as much as 20 below thehorizontal. This is mainly used for carrying out gonioscopy.

For observation by sclerotic scatter or other dissociated formsof examination the centering screw 13 is loosened, so that the slit image canbe moved away from the centre of the field of observation. The image iscentered again by tightening the screw. Carry out the techniques describedbelow.

Advanced Stepper Magnification System

Equipped with a five-step magnification mechanism, the ConXport Slit Lamp (Ultima) lets clinicians seamlessly switch between 6x, 10x, 16x, 25x, and 40x magnification. This flexibility supports comprehensive eye examinations, allowing for detailed observation of ocular tissues. The 12.5x wide field eyepieces combined with high-grade optical glass ensure exceptional clarity.


Customizable Viewing and Patient Comfort

The slit lamp offers adjustable slit width (014 mm), length (114 mm), and rotation (0180), supporting a wide variety of ophthalmic procedures. Interpupillary and pupil distances are easily adapted for individual users, while the chin rest adjusts up to 70 mm for patient comfort. Smooth base movements allow precise positioning during exams.


Precision Illumination and Durability

With energy-efficient 3W LED illumination and multiple built-in filters (Cobalt Blue, Red-Free, Heat Absorbing, ND), this slit lamp delivers clear, well-lighted images for both routine and specialized analysis. Manufactured from robust aluminum alloy and stainless steel, it promises long-lasting performance in demanding clinical settings.
