6.3 Tube and Eyepieces
Note:
For fluorescence applications, install the fluo-
rescence illuminator first → p. 26.
The tube is mounted to the stand either directly or
with the use of intermediate modules. It is fas-
tened in place with the side clamping screw
(11.1).
• Loosen the clamping screw (11.1) on the
stand.
• Insert the tube in the circular receptacle
(dovetail ring).
• Retighten the clamping screw (11.1).
• The eyepieces are inserted into the eyepiece
tubes on the tube.

6. Assembling the Microscope
6.4 Objectives
Always only use Leica objectives of tube length
× (infinity)! The standard thread is M25. The ob-
jectives should be arranged so that the magnifi-
cation increases when the objective nosepiece
is rotated clockwise.
!
Attention:
Lower the specimen stage as far as possible be-
fore assembling the objectives. Close vacant
threads in the nosepiece with dust protection
caps!
For Leica DM3000 only:
According to your equipment, the individual ob-
jectives have already been assigned certain po-
sitions at the factory.
A listing of the exact positioning of the objec-
tives is part of your supply (identification sheet).
The front control panel (Fig. 12) features six
black keys for direct selection of an objective.
Adhesive labels with the corresponding objec-
tive magnification are attached below the ob-
jective keys. (Additional adhesive labels are
supplied.)
It is recommended to insert the objectives only
after the connection to the power supply is es-
tablished → p. 33.
