Transmitted Light Base features Rottermann Contrast technique relief illumination technology Leica TL4000 RCI

The Leica TL4000 RCI stand with Rottermann Contrast, a partial illumination technology, shows the changes of the refractive index as differences in brightness.

The stand has 2 USB ports, which allow the user to control the brightness of the light source. The partial illumination technology allows a substantial increase in contrast of barely visible structures in positive or negative relief. 

Adjustable planar and concave mirrors provide dynamic relief contrast, which allows users to quickly toggle between positive and negative effects and easily distinguish between similar structures.
