Leica TL ST Transmitted Light Base: Operation
Light intensity control
The left control adjusts the intensity of the
12 V/20 W halogen illumination.
1. Switch on the illumination of the base at
the power switch.
3. Focus on the specimen.
3. Set the illumination to the desired intensity
using the left control.
Control of the transmitted light
The TL ST transmitted light base has a slider that
automatically moves the path-folding 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. 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 provide additional resolution and
information when observing semitransparent,
opaque objects.
★ Slowly pull the slider towards yourself until
the desired effect is achieved.
