2. The correct eye point
The eye point is the distance from the eyepiece to the user’s
pupil. To obtain the correct eye point, move the eyes towards the
eyepieces until a sharp image is reached at a full field of view
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. 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
