Reflected-Light Polarization - Detection of Bireflection and Reflection Pleochroism
Application
Polished sections of ores, coals, ceramic products, certain metals and metal alloys display a different
reflection behavior, depending on the orientation of the crystals or the object details. Therefore, this
technique also represents a further contrasting method.
Bireflection
•
Set the microscope as usual for examinations in reflected-light brightfield (see section 3.2.1)
•
Pull out plane-glass pushrod (3-3/
1
).
•
Insert polarization slider (3-3/
3
) until stop.
•
Insert analyzer slider (3-3/
4
); adjusting lever in center position.
•
Close aperture diaphragm (3-4/
7
) by 2/3 of its diameter.
−
The object displays bireflection if any object details feature differences in brightness and color
which vary when the stage is rotated.
Reflection Pleochroism
•
Pleochroism can be recognized by color changes in the object after stage rotation (reflected-light
polarizer slider (3-3/
3
) pushed in, analyzer slider (3-3/
4
) pulled out). (Rotary
λ
-compensator pulled out)
