Working with the Microscope
Please read the following instructions to achieve the best microscope observing results.
Setting the interpupillary- and diopter distance (binocular/trinocular type)
Using a binocular tube is less tiring for the eyes than the use of a monocular tube. In order to
obtain a smooth “compound” image as well as the right interpupillary setting, one should go
through the below steps.
Field of view before Field of view after
adjustment adjustment
•
Set the right interpupillary distance by moving the eyepieces towards or away from
each other until a compound field of view is achieved (see drawing above).
•
Close the left side eye and focus looking through the right side eye with the coarse-
and fine adjustment knobs (I)
•
Now close the right side eye and focus the left side tube by means of the dioptric
adjustment ring (B).
This procedure should be followed by each individual user.
Setting the illumination
For optimum effect in contrast and resolution one should follow the below procedure:
Place a specimen on the object stage and focus using the 4x objective, with a fully iris
diaphragm.
•
Turn the condenser in the highest position.
•
Close the iris diaphragm, until it is just visible on the edge of the field of view.
The microscope is properly set for use with the 4x objective. For each other magnification
this procedure should be repeated to ensure the best balance between contrast and
resolution.
