Installing The Objectives - Optika Italy IM-5 Serie Manual De Instrucciones

7.1 Installing the objectives

1. Turn the coarse focusing knob
nosepiece reaches its lowest position.
► For a safe transport, the nosepiece is
placed in the lowest position and the
tension adjustment collar
ed to the appropriate tension when the
microscope leaves the factory. (Fig.1)
2. Screw the lowest magnification objective
on to the nosepiece from the right side,
then turn the turret clockwise. Install the
other objectives in the same way, following
the sequence from low to high magnifica-
tion.
► Note: the objectives can also be in-
stalled through the stage opening.
(Fig.2)
► Clean the objectives regularly. In inverted
microscopes, the objectives are very sen-
sitive to dust.
► To prevent dust and contamination from
entering the microscope, cover all the un-
used holes with dust caps
► When operating, use the low magnification
objective (4x or 10X) to search and focus
the specimen, then switch to higher magni-
fications.
► When switching between objectives, slowly
turn the nosepiece until it clicks. The click
means that the objective is in the right posi-
tion, in the center of the light path.
7.2 Installing the stage extension
and the mechanical stage
The stage extension can be installed on either
side of the stage to enlarge the working sur-
face. The mechanical stage must be installed
on the right side of the microscope.
1. Installing the stage extension: screw the
bolts on to the extension, then mount the
extension from below the stage. (Fig.4)
2. Installing the mechanical stage: as for the
extension, the mechanical stage is fixed
with two bolts under the stage. (Fig.5)
