1. Limb 8nd Focusi"9 Mech..,ism
The limbissecurely attachedtothe
sturdy base and supports the observa-
tion tube, stage, condenser, revolving nosepiece and focusing mechanism.
The focusing mechanism includes
the
coarse and fine adjustments and an
automatic pre-focusing lever. This lever
is
providedtoprevent possible
contact between specimen and objective as well as
to
simplify coarse
focusing.
The
leverislocked after coarse focus has been accomplished.
This prevents further upward travel
of
the stage and automatically pro-
vides a limiting
stopifthe stageislowered then raised again.
The
automatic pre-focusing lever does
not
restrict fine focusing.

Condenser
The condenser may be mounted
on
the
condenser
mount
by first
inserting
the
condenser into
the
condenser
mount
from below, aligning
the
positioning
dotsonthe
condenser and condenser mount, and then
clamping with
the
clamping screw. Condenser centration can be
accomplished by means
of
two
centering knobs. Vertical movement
of
the
condenser can be adjusted by
the
condenser height adjustment knob.
The condenser
has an excellent resolving power,
dryoroil immersion,
from
4x
to
100x magnification objectives.
When
using
the
100x
objective,
the
distance between condenser and specimen should be
filled with immersion oil.
Note:
For use with
the
achromaticlaplanatic condenser N.A. 1.40, the
filter
mountisplacedonthe
light exit of the illuminator base, while
either
the
Abbe N.A. 1.25orN.A.

condenser incorporates its
own filter mount. When
the
N.A.

condenserisused for super
