9.6 Filter for Color Contrast

For the differentiation of color deviations of two objects being compared, the two filters CRA (red) and CGA (green) in sliders (Fig. 54) are pro- vided. They are inserted into the filter recepta- cles in the macroscope holders (55.1) above the objectives.

For adjusting the superimposed image with col- or contrast, first set the button on the control panel to MIX (for composite imaging).

If the objects of comparison overlap in their es- sential structures, these only appear in their original color where matching details are present.

Depending on the assignments of the filters to the two beam paths, the deviations appear in ei- ther red or green.

This requires that the intensities of both light sources are carefully matched.
