Using the Condenser
The Ni-E basically uses a motorized universal condenser that supports all microscopy methods (bright-field, dark-field,
differential interference contrast, and phase contrast). It can also use various manually-operated condensers such as
manual universal condenser.
Use the condenser appropriate for the microscopy method and objective.

Some condensers may have limit in their use depending on the magnification of the objective. See the table below so that
you can use a condenser properly.

magnification, pull out the slide.
For objectives with 2x or 4x
magnification, push in the slide to
prevent vignetting.
