Leica M Series User Manual
Transmitted-light control
The transmitted-light base TL BFDF has a slider
that automatically moves the deflection mirror
in the base when moved. The mirror is kept in
the correct position at all times and permits
smooth changeover between bright field and
opaque transmitted light.
Bases
Bright field
Bright field is suitable for examining translu-
cent objects featuring contrasting structures.
The object is directly illuminated from below
and is seen in its natural colors against a bright
background.
Move the slider backwards until the desired
effect is achieved.
Inclined transmitted light
Transmitted light that traverses the object
obliquely will produce effects advantageous for
observing semitransparent, opaque objects.
Slowly pull the slider towards yourself until
the desired effect is achieved.
