The gallery contains a comparison of sample images obtained by different observation methods - in a bright field, with relief contrast with a help of LUMICRA sliders (Classic or Tunable) and with phase contrast (standard Leica phase slider). Various preprepared sample slides (without staining or stained) were used for the imaging. These slides are intended mainly for observations with phase contrast, or by DIC and polarizing microscopy. Images were taken with a DM750 microscope equipped with Leica IIC50 or FLEXACAM C1 cameras. The resolution for the display has been reduced. Original images can be supplied on request.
A significant relief effect is evident in images taken with LUMICRA sliders. This contrast methond allows much easier observations of the tissue, cells or organisms with hightlighted details on the surface.
To compare images drag the blue element with the arrows to the left and right.
