Incident light axis (IL) with 106 z lamp housing
• When a supply unit is used, it is turned on first.
• Activate the incident light axis using the TL/IL
function key. FLUO (Leica DM4000 B/ DM5000 B)
or IL (Leica DM4000 M) appears in the display.
• Insert the reflector for lamp adjustment
(Fig. 45) into the filter turret in place of a filter
cube. (See →
p. 26).
Note the name of the exchanged filter cube.
• Turn the reflector into the light path.
The reflector has reached the correct position
when the name of the exchanged filter cube is
shown in the upper right of the display.
Caution:
Never look directly into the light path!
When switching to the BF or Smith reflectors,
there is a danger of being glared!
For the 106z lamp housing, the direct filament im-
age (for halogen lamps) or direct arc image (for gas
discharge lamps), and its mirror image are focused
separately and adjusted to each other.
On the left side of the microscope, there is an
adjustment window (1.14, p. 12) for mapping the
light source.
While observing the light source in the adjust-
ment window, the lamp is adjusted as follows:
