2.5.7 14x40 mm stop sliders for aperture
and field diaphragms
To adjust the reflected light beam path using the
KÖHLER method, one 14x40 mm stop slider
(
723H
Fig. 2-15/ 4 ) mounted in the upper part of the
stand is required to function as a field diaphragm
(
F ) and another to function as the aperture
diaphragm (
A
).
•
To open the diaphragm, turn the knurled wheel
(
724H
Fig. 2-15/ 1 ) up.
•
To close the diaphragm, turn the knurled wheel
(
724H
Fig. 2-15/ 1 ) down.
•
To center the diaphragm to the beam path,
adjust the centering screws (
725H
Fig. 2-15/
2
and
3
)
with an Allen wrench (AF 3).
NOTE
When applying fluorescent light, you may want to mount an FL attenuator (if not pre-
installed) on the level of the aperture diaphragm in order to attenuate the fluorescence
radiation.
