When in place insert eyepieces in the eyetubes of the binocular body and mount the objectives on the
centering objective nosepiece, starting with the lowest magnification, but positioning the 10X in the fixed
(not centerable) opening. Then position the others to the right in order of increasing magnification.
Note: It is important that you change magnifications by rotating the milled nosepiece ring, not by
grasping and pulling the objective barrels. Doing this puts strain on the objective housings which can
cause some decentering.
A focusable cross-line eyepiece should be used in the slotted eyetube. Make sure that it is Keyed
into the slot in the eyetube, as its orientation is important and should not change. The cross-line should
be sharply focused by turning the focusing ring.

IMPORTANT!
Before plugging the illuminator into any electric outlet, make sure that transformers and illumination
bases supplied to you are suitable to the current available (See voltage indication at the bottom of limb).
The ML9400 series polarizing microscope features an in-tube, slide-in Bertrand Lens. Fitted with it is a
field-limiting aperture which allows isolation of small features in the center of the field. Thus the
characteristic interference figures for small crystalline elements can be observed and studies. These
effects only occur when both analyzer and polarizer are in the optical path, the polarizer being set at 0
degrees. The in-tube design of the Bertrand Lens makes it possible to use it equally well with binocular,
trinocular and monocular bodies.

OPTICAL SET-UP AND TRANSMITTED LIGHT ILLUMINATION
A sensitive tint plate (first order red) and mica 1/4 wave plate are supplied with the ML9400 series
polarizing microscope as standard. These are fitted in plates with standard DIN dimensions, sliding in a
slot cut in the tube just above the objective nosepiece.
(1)Turn on the Transmitted Light Illuminator by turning the Switch . Place the specimen slide you wish
to examine on the microscope stage and rotate the 10X objective into position for focus.
(2) Move the substage condenser up to its top position, using the rack and pinion focusing control .
Check to make sure that both the field iris and the aperture iris are fully open.

(3) Focus down on your specimen slide until detail can be seen. Adjust the brightness of the in-base
light source, using the intensity control knob , left-hand back on the base.
BINOCULAR ADJUSTMENT
Comment: Using a binocular body is much more efficient and less tiring than a monocular body, but it
must be adjusted correctly. When it is perfectly adjusted the images coming from the two eyepieces are
fused into one better image in eyes of the observer.
PHOTOGRAPHY AND TELEVISION
PHOTOGRAPHY
Photographic documentation of microscope visual images is most conveniently achieved by using the
trinocular (photo-binocular) bodies for use with 35mm SLR Camera or PMX100 Large Format Camera.
In the case of the ML series of biological, metallurgical and polarizing microscopes a trinocular body is
equipped with a sliding switch-over beam-splitter component which either (1) allows all of the light to go
to the visual eyepieces or (2) directs 80% of the image-forming light upwards to the film plane of a
35mm SLR camera, while still sending 20% of the light to the binocular eyepieces.
In the system the MA150/50 or MA150/60 Camera Attachment should be used with the SLR camera of
your choice. Please note that one of the large range of T2 Adaptor Rings suiting to your camera should
be ordered separately.
These adaptor rings are intended to compensate for the small differences in effective distance of the
film plane in your camera - so as to ensure that photographs are optimally sharp, and achieved without
wastage of film in trial shots and experimentation.
In addition special low-power camera eyepieces (2.5X, 3.3X and 5X) are available and recommended these will give you maximum field coverage on your specimen while using the convenient and
economical 35mm film format.

CENTERING OF OBJECTIVES
When the microscope is shipped to you the objectives are factory par-centered. Therefore, check and
make sure that the objectives have been precisely seated on the optical axis. If it is even lightly off axis
the centering is required with the Hexagon keys supplied in the following way:
(1) Focus down on your specimen through the 10X objective mounted in the non-centerable locked-up
opening, aside from the other floating centerable nosepiece holes, and memorize the point of the
specimen appearing just on the eyepiece cross-line center.
(2)Turn the nosepiece and bring the next higher power objective to the position, and focus on the
specimen if necessary, and see whether the pinpoint of the specimen you memorized before is located
just at the cross point of the mark.
(3)In case the memorized pinpoint is
seen away from the cross point, it
must be brought to the cross point by
the use of the provided two Centering
Screws, which can be inserted into
the key holes on the nosepiece ring
and turned to move the pinpoint to
the cross point.

(6)Raise or lower the substage condenser so as to
focus the field iris as sharply as possible in the plane
of your specimen. When this is done open out the
field iris until it is just outside the field of view.

(7)Removing one of the eyepieces, observe the disc of light coming from the back of the objective in
use. Close down the aperture iris , using the lever on the substage condenser, until only about 70%80% of the disc of light observed remains visible. (Note that the microscope is now set up for use with
the 10X objective. Similar adjustments to those mentioned above should be made when using any of
the objectives required.)
(8)Regarding the note above, if you choose the 100X objective, immersion oil must be applied to the
specimen slide so that, when this objective is swung in and focused, both the specimen slide and the
100X objective are in good, bubble-free contact.
(9)The tension control knob is provided to
allow the individual user to adjust the focus
tension to his/her own preference. Tension may
be increased by turning the knob with a
counterclockwise motion. A lighter tension may
be set by turning clockwise.

The Analyzer is mounted in an in-tube slider which moves the analyzer in and out of the optical path.
When “in”, and with the substage polarizer also “in” and set at 0 degrees, these elements are said to be
“crossed” and the field of view is said to be “extinguished”. In this condition the field of view is dark except for optically active elements in the field, which rotate the angle of polarization and thus become
visible against a dark background. This is the basic advantage of a polarizing microscope.

optics.
Store the microscope in a safe, clean place when not in use for an extended period of time.
CLEANING
Clean exposed lens surfaces carefully with a pressurized air source, soft brush or clean soft cloth. Too
much finger pressure may damage lens coatings.
Immersion oil should always be promptly cleaned from high power oil immersion objectives after every
use.
