5.4 Performing Polarization Examinations with
Transmitted Light
¢
You are using Primotech D/A POL or Primotech D/POL Conoscopy
¢
The sample is illuminated by transmitted light only
¢
No polarizers or analyzers are in the beam path
¢
The objectives are centered (see Centering the Objectives [} 33])
Turn the polarizer ring under the sample to the 0° position.

2 If desired, observe the sample in the polarized light, for example to determine
the fracture direction of a material.
3 Insert the fixed analyzer into the horizontal slot of the intermediate tube.
Alternatively, insert the rotatable analyzer, set to the 0° position, into the slot.
4 Rotate the stage and observe how the sample changes color.
5 To investigate the sample further, insert a compensator in the 45° slot on the
microscope stand.
5.5 Performing Polarization Examinations with
Reflected Light
¢
The sample is illuminated by reflected light only
¢
No polarizers or analyzers are in the beam path
Insert the fixed polarizer into the vertical slot of the intermediate tube.

2 Insert the rotatable analyzer, set to the 0° position, into the horizontal slot of
the intermediate tube.
3 If desired, rotate the sample and observe how the sample changes.
