diaphragm lever to the open side ( ).
· Useful information
If you cannot get the sufficient contrast in the phase contrast
observation, you may be able to get the high contrast image

Selecting the objective
Rotate the revolving nosepiece a to engage the objective b with
the magnification to be used for observation in the light path.
If the focal point of the specimen is higher than the
stage surface, the objective
b
may collide with the
stage center plate or the plain stage when the revolving
nosepiece
a
is rotated. In this case, use the objective
with a long W.D.(working distance) or the stage center
plate with a large aperture.
