5.8 Adjustment of the illumination for incident light
Just like the components of transmitted light illumination, those of reflected light
illumination can be adapted to different application requirements.
The following components are available:
Luminous field diaphragm and aperture diaphragm
The two shutters have the same functions as explained in the transmitted light setting
(
see section 5.7
). These shutters are opened and closed using the levers located on
the top of the incident light unit.
Color filter
The color filter slider contains two round openings. One with integrated blue filter and
one empty. This slider has the inscription "2" and must therefore be brought into the
insertion point also with "2" as the inscription. Depending on the requirements, one of
the two openings must be engaged in the beam path.
Polarization unit (analyzer / polarizer)
In order to bring the analyzer into the beam path, the analyzer slider must be brought
into the insertion point on the side below the microscope head so that the integrated
rotary wheel points outwards in order to be able to set the desired alignment of the
analyzer. If the analyzer is not to be used, it must be completely removed from the
instrument, unlike the other sliders.
The polarizer slider contains two round openings. One with integrated polarizer and
one empty. This slider has the inscription "1" and must therefore be brought into the
insertion point also with "1" as the inscription. Depending on the requirements, one of
the two openings must be engaged in the beam path.
Diffuser
Directly behind the lever of the aperture diaphragm is a small insertion point for the
diffuser. It is integrated in a round opening of a small black slider. This slider can be
inserted to let the light of the LED diffuse evenly.
