Leica M Series User Manual 15
Leica engineers were careful to ensure that the
new M series – like its predecessors – remains
compatible with existing series. This means
that objectives, bases, tubes and so on can be
reused.
Objectives
All new objectives of the M series are parfocal,
meaning that when used with the objective
nosepiece, they can be replaced while keeping
the specimen in perfect focus.
If you prefer, you can continue to use the previ-
ous objective series. In this case, parfocality is
no longer guaranteed.
Tubes
The interface between the optics carrier and
the tube has remained the same, so exist-
ing tubes fit the new M series. The new tubes
are designed for eyepieces with field number
23, while the predecessor models were only
designed for field number 21, resulting in a
smaller object field.
Eyepieces
However, the new M-series eyepieces models
have an audible and tangible click to provide
immediate feedback in case of accidental
adjustment.
