• Switch transmitted-light illumination ON by
pressing the lower knob (Fig. 26/1).
• With the transmitted light ON, turn this knob to
adjust the illumination intensity.
• Adjust the bright field (BF) by pushing the
sliding knob (Fig. 26/2) into its rear position
(BF).
• Turn the sliding knob (Fig. 26/2) to swing the
clear or diffuse mirror into position or to adjust
the inclination angle.
Clear mirror for high-contrast bright
field, diffuse mirror for homogenous
bright field.
• Change over to dark field illumination (DF) by
pushing the sliding knob (Fig. 26/2) into its
front position.
• Turn the mirror until the specimen structures
are brightly lit against the dark background.
By pushing the sliding knob (Fig. 26/2)
into a central position and by tilting the
mirror, oblique light effects (RC) are
created which are very well suited to
display non-coloured specimens.
