Transmitted-light Base TL ST: 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.

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.

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.
