Leica TL RCI: Methods in Transmitted Light

Vertical bright-field illumination
Suitable for stained amplitude specimens with
sufficient contrast.
The light beams are deflected vertically through
the specimen. This results in an accurate bright
field with maximum brightness.
Leica M Series User Manual
Inclined transmitted light
Suitable for semitransparent, opaque speci-
mens such as foraminifera and fish eggs. Move
the deflection mirror until the desired data are
visible.
Bases
Single-sided dark field
Suitable for fixed specimens and fine structures.
The flatter the angle at which the light beams
are deflected into the specimen plane, the
darker the substrate appears. A dark field-like
transmitted light is created. Outlines, fine edges
and structures are bright, in contrast with the
dark background, through diffraction of the
light beams on the dark background.
