Procedure
1. If using the objective position with a DIC position, remove the DIC slider, if necessary.
2. Swivel the Pol objective
1
into the beam path.
3. Swing the DIC P&C reflector module
2
or the Pol P&C reflector module into the beam
path. Slide the analyzer slider
4
into the compartment.
4. Alternatively, slide the analyzer slider
4
and the polarizer slider
5
into their compart-
ments, if applicable.
5. Place the sample on the rotary stage Pol
3
.
6. Swivel in the objective with the desired magnification.
7. Focus the sample.
8. Turn the rotary stage Pol to examine the sample in the polarization contrast.
à
The sample appears in polarization contrast while turning the stage.
9
A sample is bireflectant when the sample details show differences in brightness and color
which change when the stage rotates. For samples with low bireflectance we recommend us-
ing the analyzer with a rotatable lambda plate.
9
Pleochroism is present when the color of the sample changes as soon as the stage rotates
(overhead polarizer is turned on, analyzer is turned off).
5.5.7 Setting Up for Reflected Light Fluorescence Microscopy
The present section applies to the following microscope type:
§
Axioscope 5 TL/FL (430035-9061-000)
For more information about the method, see chapter
Reflected Light Fluorescence Microscopy
WARNING
Hazardous light emission
The light source belongs to Risk Group 3 as specified in IEC 62471 and emits LED radiation and
UV radiation. Skin or eye injury can result from the exposure.
4
Avoid any eye and skin exposure to the light-emitting aperture of the light source.
4
Avoid exposure of skin to the radiation. Use suitable protective equipment/protective
clothing if required.
4
Before installing or removing the light source always make sure it is switched off.
NOTICE
Property damage due to heat emission
Microscope lamps emit a lot of heat which could damage the heat-sensitive fluorescence fil-
ters.
4
Do not remove the heat protection filter when using a fluorescence filter.
Info
The adjustment of reflected light fluorescence is facilitated by starting with an objective of av-
erage magnification, e.g. EC Plan-Neofluar 20x/0.50, and a sample of high fluorescence.
Demonstration samples can also be used for the start-up.
