8. Operation
8.8 Eyepieces
Note:
The eyepiece’s aperture protector must be re-
moved or folded back, during microscopy while
wearing eyeglasses. We recommend removing bi-
focals and spectacles with progressive-addition
lenses when using the microscope.
• For the adjustable tubes with documentation
output, choose the 100% VIS position.
Eyepieces with inlaid reticle
• Focus the reticle by adjusting the eyelens.
• Focus on the object through this eyepiece.
• Then, close that eye and focus on the object
by adjusting only the second ocular.
Correction for Vision Problems
• With your right eye, look through the right eye-
piece and bring the specimen into sharp fo-
cus.
• Then, with your left eye, view the same speci-
men and rotate the left eyepiece tube until the
object is brought into sharp focus. Do not
change the Z position in the process!
Note:
We recommend running a teach-in via the Leica
Application Suite (LAS) software when using eye-
pieces not included in the scope of delivery. This
will ensure that the total magnification shown in
the LeicaScreen is correct.
8.9 Objectives
Changing objectives
Leica DMI3000 B and Leica DMI4000 B:
Select objectives manually with the objective
turret.
The objective turret of the DMI4000B is coded
so that the selected objective is shown on the
display.
Leica DMI6000 B:
The objectives can be selected with the function
buttons on the stand or the SmartMove, or by
manually turning the objective turret. When
changing objectives manually, please ensure
that the turret clicks into position.
The positions of the objectives in the objective
turret have been specified at the factory and
must be observed when installing the objec-
tives.
(→ also see Objectives, p. 43).
When selecting an objective, the microscope
automatically selects:
• the optimal setting for the field diaphragm
• the optimal setting for the aperture diaphragm
• the light intensity for the current contrast
method
The objective magnification and total magnifica-
tion are displayed on the LeicaScreen.
