The Leica TL4000 RC base with Rottermann Contrast™ technique, a relief illumination technology, shows the changes of the refractive index as differences in brightness and provides ideal lighting conditions for observation and imaging with any high performance Leica Stereo Microscope, especially at high magnification. The unique technology allows a substantial increase in contrast of barely visible structures in positive (appear elevated) or negative (appear as depressions) relief for many molecularor developmental biology applications. Adjustable mirror with planar and concave mirror position provides dynamic relief contrast, which allows users to toggle quickly between positive and negative effects and easily distinguish between similar structures.
Rottermann Contrast™ – relief illumination technology provides increase in contrast of barely visible structures in positive and negative relief.
Sliding mirror with adjustable position - helps control contrast and easily distinguish between similar structures.
Slide-on™ mechanics – enables XY stage use with transmitted light at the focal point.
Anti-shock and anti-vibration pads – absorb shock and vibrations for high quality imaging.
