[Procedure for attaching the DIC module on the condenser, dark-field module, and 2-4x
auxiliary lens]
Holes (5), (6), and (7) have their positioning pin and module fixing screw.
• First check that the tip of the module fixing screw is not inside the hole. If it is inside, place that hole into
the optical path, lift the Ph module centering knob at right rear of the condenser, and turn the centering
screw to loosen the module fixing screw. After it is loose, pull out the knob and restore it to the original
position.
• Determine the orientation of the module so that the positioning pin on the hole can be inserted into the
groove on the opposite side of the surface with the module name and attach the module. As the grooves
for the dark-field module and 2-4x auxiliary lens are wider compared to the pin, they do not need a strict
orientation, unlike the DIC module on the condenser.
• Bring the attached hole into the optical path, turn the centering screw, and tighten the module fixing screw
to secure. After it is tightened, pull out the knob and restore it to the original position.
[Attaching PH module]
Holes (2), (3), and (4) have a spring.
• First check that the tips of the two Ph module centering screws are not inside the hole. If it is inside, place
that hole into the optical path, lift the Ph module centering knob at right and left rear of the condenser,
and turn the centering screw to loosen the module fixing screw. After it is loose, pull out the knob and
restore it to the original position.
• Place the module with its name facing up.
• Place it into the hole by pushing the spring away.
(3) Attach the nameplate sticker.
Affix a nameplate sticker for each module to the turret perimeter. Arrange stickers so that, when the
condenser is attached to the microscope, the module name currently in the optical path is always indicated
by the sticker at the front position. (i.e., stickers are put across from the corresponding module)
Put the sticker [O] for the empty hole.
Put the sticker [NR] provided with the DIC module when [NR] type of DIC module on the condenser has
been attached. This sticker is not provided with the universal condenser.
