The SL-D8Z is part of Topcon's SL-D-series digital slit lamps. It can be used as a conventional examination instrument or as a digital slit lamp with the several imaging options.

Used as a conventional examination slit lamp, the SL-D8Z incorporates 6 filters: a blue filter, red free filter, UV-cut, IR-cut, ND, and an amber filter. The amber filter improves the contrast and colour of retinal images.

Digital applications
Used as a digital slit lamp, the SL-D8Z will be seamless integrated with:
-DC-3, an 8 megapixel camera
-DV-3, an 3.14 megapixel video camera

Other options
The SL-D8Z slit lamp has many options such as a yellow filter, back ground illumination, diaphragm unit, Topcon Fundus Viewer, FV-1L and FD-21 Flash Device.

FD-21 flash device and photo attachment
The FD-21 flash device and photo attachment enables the clinician to make superb photos of posterior and anterior segments in the eye. Excellent clarity, colour balance and depth of field enhance the examination. The FD-21 fits on SL-D7 slit lamp and SL-D8Z and is combined with a Nikon SLR camera.

The Topcon BG-4M Meibography attachment enables the clinician to view Meibomian glands with invasive techniques.

Diaphragm unit
The diaphragm unit enhances the focal depth in the lower magnifications of the complete anterior segment. Thus the clinician can diagnose faster and images have a better focus.
