There are two major reasons why an imaging slit lamp should have a quality background illumination system:
- Overview images: for this the diffuser will work but using the background illumination and slit beam (diffused) will produce a shadow free illumination with natural colors and two light reflexes.
- Slit images: the background illumination is required if the view through the slit lamp is to be reproduced on screen.
This LED Background illumination are available for all kinds of slit lamps. Easy set.
