@ Analyzer, Polarizer and Reticles
• Hold each slider with its indications facing up
or toward you, and insert it into the
corresponding port.
• When not in use, insert their corresponding
dust-tight sliders respectively into the above
ports. This prevents dust or dirt coming into
the microscope base.
• The polarizer slider with or without the first
order red compensator can be inserted into its
port either from the right or left side of the
microscope. It is advisable to insert the slider
from the side where the stage movement
knobs are not located. This makes the
operation of the polarizer easier.

@ Photomicrographic
Attachment (option)
Refer to the instruction manual of your photo­
micrographic attachment on its assembly or on
how to perform photomicrography with that
attachment.
If an additional photomicrographic attachment is
required besides the photomicrographic system
built in the microscope base, mount one to the
side port.
• Fix the viewfinder, the FM-mount, the dark
box and other components to the main unit of
the photomicrographic attachment by referring
to its instruction manual.
• Detach the cap from the side port tube. Insert
an PL projection lens into the side port tube.
Push in the projection lens into this tube until
it reaches the limit. Slightly tighten the
projection lens fixing screw with the
hexagonal screwdriver to fix this lens.
• Face the viewfinder of the assembled
photomicrographic attachment toward the
front of the microscope. Insert the assembled
attachment into the side port tube. Confirm
that the attachment reaches the limit in this
tube, and tighten the photomicrographic
attachment/fV adapter clamp screw to fix that
attachment.
