Adjusting the Reflected Light/Dark-Field
(1) Application
The reflected light/dark-field method is applied when samples are examined which do not have areas
with different reflectivity (ideal bright-field samples), but which show scratches, cracks, pores (brief:
deflections) on the plane surface. All such light scattering details appear bright in the dark-field while the
reflective plane areas remain dark.
(2) Instrumentation
−
Axio Scope.A1 with adjusted halogen lamp HAL 100 mounted on the reflected light barrel
−
Objectives Epiplan-Neofluar, EC Epiplan-Neofluar, Epiplan with the additional label "HD"
−
Reflector module dark-field ACR P&C for reflected light in the reflector turret/slider
(3) Adjusting the reflected light/dark-field
•
Adjust the microscope as described in chapter
672H672H
4.1.7 for reflected light/bright-field. The field
diaphragm image should lie just barely outside of the edge of the field of view in order to avoid
reflexes.
•
Swing reflector module dark-field ACR P&C for reflected light on the reflector turret in the beam path.
•
Remove condenser slider 6x20 if mounted.
•
Swing in objective position with dark-field objective (HD) on the nosepiece.
•
Open aperture diaphragm fully and switch off or remove neutral filters if applicable.
•
Put down the sample and adjust the focusing if necessary.
