(4) Installing the eyepieces
The 10x (Field No. 20) eyepieces are attached to the
eyepiece tube before shipment.
When changing to a 15x (Field No. 18) eyepiece (optional),
be sure to change both the right and left eyepieces together.
The right and left eyepieces should be of the same
magnification.
Replacement of eyepieces
To remove the eyepieces, loosen the fixing screws for the
eyepieces. The microscope does not come with a
hexagonal wrench (the distance between opposite sides is
2.5 mm) to loosen the fixing screws. Contact your nearest
Nikon representative if you have any questions.
Installation of the eyepieces
(5) Installing the objective
Screw an objective into the revolving nosepiece. Screw the
objective firmly to the end.
First, remove the specimen from the stage and lower the
stage. Remove the objective while holding it by both hands
so that it does not fall, and then install a new objective.
Set the objectives in such an order that the objective
magnification increases as the revolving nosepiece is
turned clockwise (as viewed from the top of the
microscope).
Installation order of the objectives
When you have purchased the microscope as a set, three
objectives are already installed to the revolving nosepiece.
When adding an objective or replacing the objective with
another one, also install it in the magnification order as
described above.
Example of order of installing the objectives
(6) Installing the condenser
The condenser is attached to the microscope before
shipment. The condenser is fastened by a leaf spring,
allowing attachment or removal without the use of tools.
When attaching or removing the condenser, raise the stage
to its maximum height, and lower the condenser to its
minimum height.
The condenser can be removed by pulling it towards you.
To attach the condenser, fit it into the dovetail at the mount,
and push the condenser in all the way.
Note on removing the condenser
If you pull out the condenser with the centering screw fully
loosened, the inner frame of the condenser mount may be
removed together. In this case, put the inner frame back to
the dovetail, and then tighten the centering screw.
Centering work after reattaching the condenser can be
performed without problem.
If the inner frame is accidentally removed
