Condensers (3-1/23)
Depending on their type, condensers (3-7/1) are
equipped as follows:
− 5- or 6-position turret for:
brightfield: H
phase contrast: Ph0, Ph1, Ph2, Ph3 with
centerable stops
interference contrast: DIC
Varel contrast: Var1, Var2
− Aperture diaphragm (iris stop). Use knurled
knob (3-7/2) to open and close the aperture
diaphragm.
− Turn the turret wheel (3-7/4) to swing the
brightfield insert or the contrast stops into the
beam path.
− The brief description of the set turret position
(e.g. H) is displayed to the user at the front.
− Condensers for Varel contrast are equipped
with a knurled knob (3-7/3) which allows the
position of the Varel stop to be changed when
the Varel turret position has been set. The lever
(3-7/5) permits switching between Var1 and
Var2.
− The condensers 0.35 and 0.55 for phase
contrast require the use of one SW 1.5 Allen
screwdriver each (plugged in at 3-8/1) to center
the phase stops.
☞
The condenser turrets feature the so-called automatic diaphragm mechanism, i.e. the aperture
diaphragm (iris stop) is opened completely when a phase stop position is switched on. When a
new turret position is switched on, the aperture diaphragm is automatically reset to its last
opening.
