Leica DM100 User Manual 18
The objectives are already installed
on the Leica DM100 at delivery. The
following description shows how to (un)install
the objectives if they have to be removed for
cleaning or replaced by other objectives.
Your Leica DM100 is normally supplied
with objectives of magnification levels
4×, 10×, and 40×. The 100× objective, which is
also used for oil immersion, can be retrofitted
at any time.
Always turn the objective nosepiece by
its knurled ring. Never turn the objective
nosepiece by using an objective as a handle.
Removing Objectives
1. Unscrew the objectives to remove them.
The Proper Sequence
When inserting the objectives, you can
begin with any available space on the
microscope. Continuation of the sequence,
however, has to be selected such that the
magnification always increases when turning
clockwise:
