Fluorescence immersion condenser
N.A.: 1.35 oil
Free working distance: 0.37mm
Use: For fluorescence microscopy in brightfield, with
objectives between 10x and 100x for highest
requirements of brightness and image contrast.
When working with normal light, usable with 4x
objective; the lower condenser turret must be turned
to 4, the frosted auxiliary lens.
Brightfield immersion condenser
N.A.: 1.30 oil
Free working distance: 0.42mm
Use: this condenser can also be used for normal
contrast fluorescence and fluorescence microscopy.
It gives a pale cast to the image background. Can be
used for fluorescence work with 10x to 100x
objectives. When working with normal light, usable
with 4x objective; the lower condenser turret must
be turned to 4, the frosted auxiliary lens.
Phase ring knob with phase and anoptral rings
This turret contains the phase and anoptral rings
that are inserted into the relay path. For the 10x
objective use the phase ring 10 or anoptral ring 10A.
The rings for other objectives are also marked with
the objective magnification. In the knob position 0
(red dot) the beam path is empty.
Ring aperture for contrast fluorescence
There are specially designed UV-transmissive ring
apertures, allowing the brightfield immersion
condenser to do contrast fluorescence. The rings are
included in the lower condenser turret. When
changing objectives, each should be centered to the
image of the corresponding ring diaphragm.
Otherwise it will need to be centered as on page B6.
Blocking filter slide for transmitted-light
fluorescence
The blocking filter slide is inserted from the right in
the transmitted-light optics carrier. The spring plate
on the front of the optics carrier is pulled slightly out
and the empty slide removed. The colors of the
notch filters must be visible from the front.
Lamp shade
The lamp shade protects the observer from stray UV
light. It is magnetically attached below the body of
the microscope stand.
UV light blocking tube
The light tube is placed on the light well of the
microscope base plate and protects from UV glare.
In addition, it can be used to hold various light filters
with a diameter of 50mm.
