Tube Optics; Operation - Leica DMR Bedienungsanleitung

Operation

Switching on
Turn on mains switch (42.14).
Set selector switch to transmitted or incident
light (42.13). If using a gas discharge lamp: turn
on external switch and check lamp adjustment
immediately (see page 90).
!
Caution:
Leica power units are immune to interference.
Nevertheless we recommend you ignite gas
discharge lamps before switching on the other
components, particularly if your power unit is
not from the Leica range.
Switchable mirrors (3.3, 61.7) only: Switch to left
or rear lamphousing.
Engage or disengage neutral density filter* (42.8,
42.15, 48.23, 65.10, 30.4, Fig. 9), depending on
required brightness.
Adjust brightness with dial (48.24). The numbers
are not absolute values, but merely enable
reproducible settings. The light-coloured dot on
the dial indicates the setting for about 3200 K for
photography on indoor colour film and TV
microscopy. See page 61 for DM RXE stand.

Tube optics

Disengage Bertrand lens (42.2), Switch on tube
factor 1x. If you have HC P (Pol) tube optics, just
switch to tube factor 1x (page 83). See page 67
for how to set tubes and eyepieces.
