I 0. Zoom Dial
The zoom dial is used to operate the zoom lens built in the microscope. Zoom
magnification ranges from 0.8x to 2x. Tum this zoom dial to set the desired magnification
within the above range.
• Intermediate magnification set by the zoom dial is
effective both to microscopic observation and
photomicrography (35 mm film or large format
film).
• It is not necessary to adjust the magnified
dimensions of the sample image observed with a
micrometer since the intermediate magnification is
equally effective to both the micrometer and sample
image.
• Intermediate magnification is not effective to
observation or photomicrography performed through
the side port.
• The zoom dial clicks at 0.8x, lx, 1.25x, 1.Sx and 2x.
