With the universal phase contrast slider (I)
phase contrast and bright field observa-
tion is possible. The slider matches with the
10x/20x/40x phase contrast objectives. Po-
sitions without ring diaphragm can be used
for bright field observation.
Insert the phase contrast slider (I) into the
corresponding slot of the condenser (II). The
label of the slider should face the user.

You can insert the phase contrast
slider from either side of the condenser.
Make sure that the phase contrast
slider is always fully aligned in the
light path. An audible "click" indi-
cates the phase contrast slider and the
optical axis position are accurate.
