3. Adjusting the diopter
This chapter is only applicable for bino and trino’s
•
Set diopter adjustment ring to zero (I)
•
Close the left eye and focus the right tube by adjusting the coarse- and fine adjustment knobs (O)
•
Close the right eye and focus the left tube with the diopter adjustment ring
This procedure should be followed by each individual user. When more users are working on the same microscope it is
recommended to remember your own diopter setting for a quick set-up during new microscopy sessions
Abbe condenser
Beneath the object stage an Abbe condenser N.A. 1.25 is mounted (on all models except the MB.1001 and MB.1005-X
models, which have a fixed 0.65 condenser). The condenser can be adjusted in height by moving the lever beneath the
(mechanical) stage (N). By adjusting the condenser you can focus the light on the specimen for an optimized contrast.
The condenser is factory pre-centered. If needed, the following procedure can be followed to center the condenser
A.
Move the condenser to its highest position
B.
Select the 4x objective and place it into the light
path and focus the specimen
C.
Slide the lever to adjust the diaphragm to the
smallest position
D.
Adjust the condenser height to the point where
the image is the sharpest
E.
Adjust the center adjustment screws using an
allen key and move the image of the condenser
ring to the center of the field of view
F.
Open the diaphragm gradually
G.
The condenser is centered correctly if the image
remains in the center when you open the
diaphragm
Use of the S100x oil-immersion objective
Some Euromex MicroBlue microscopes are equipped with an S100x N.A. 1.25 oil immersion objective. Please follow the
instructions below on how to use this objective:
1.
Remove the dust protection cap from the revolving nosepiece to mount the S100x objective (the objective can
be premounted)
2.
Focus the image with the S40x objective
Turn the revolving nosepiece so the S100x objective almost reaches the click-stop
3.
Put a small drop of immersion oil on the center of the slide (always use Euromex Immersion oil)
4.
Now turn the S100x objective so that you feel the click stop
5.
The front lens is in contact with the immersion oil
6.
Look through the eyepiece and focus the image with the fine adjustment knobs
7.
The distance between the lens of the objective and the slide is very small!
8.
In case there are small bubbles visible, turn the S100x objective a couple of times from left to right so that the
front of the objective moves in the oil and the bubbles will disappear
9.
After using the S100x objective, loosen the slide protection handle and turn the table with the course
adjustment knobs downwards until the front lens doesn’t touch the oil any longer. Clean the front lens of the
S100x objective
