NOTE Should the setting range of the centering screws not be sufficient, please check whether the
condenser is at the front stop and the slider has engaged. Exact imaging of the annular diaĆ
phragm requires a plane-parallel object.
• Replace the eyepiece telescope by the eyepiece
again.
• The center position of the phase-contrast sliders
permits brightfield illumination, the brightness of
which is matched to that of the phase-contrast
image by means of an attenuation filter (gray filĆ
ter) (2Ć17ā/ā 2 ).
• When using different Ph objectives with Ph 0,
PhĂ1 and Ph 2, pay attention to the correct assignĆ
ment of the annular diaphragms (see table beĆ
low).
