Leica DMIL Mode D'emploi page 13

Incident-light fluorescence facility*
The microscrope version with incident-light
fluorescence facility contains the integrated
fluorescence axis and the lamp holder for
mounting of a lamp housing.
Fluorescence filter block slide*
The fluorescence filter block slide holds up to 3
fluorescence filter blocks. The filter block slides
can be moved to three alternative switching
positions.
One position of the slide can also be used as a
bright-field position by leaving it empty (no filter
block inserted).
Lamps and lamp housings* for the
incident-light fluorescence facility
For incident-light fluorescence, an additional
illumination is required. On the DM IL, all lamp
housings of the 106 and 107 ranges can be used.
Depending on the version used, the controls for
the lamp housings are located on the right or left
side.
The LH 106 and LH 107 lamp housings are only
used with a 12 V/100 W halogen lamp which can
be centred in the X/Y plane. Both lamp housings
are not equipped with a reflector but have
diffusing screens, heat-absorbing filters and
focusable aspheric collectors.
The LH 106z lamp housing is similar to the LH 106
lamp housing but has a reflector which can be
centred and focused. It also contains a 4- or 6-
lens collector (quartz collector on request).
The following lamps can be used with their
special sockets:
Halogen lamp, 12 V/100 W
Hg ultra-high pressure lamp 50 W, AC
Hg ultra-high pressure lamp 100 W, DC, without igniter
Hg ultra-high pressure lamp 100 W, DC, with igniter
Xe ultra-high pressure lamp 75 W, DC, with igniter

This requires to raise the microscope stand with a base to
increase the necessary clearance.
Power unit*
An external power unit is used to regulate the
lamp for incident-light fluorescence and the
corresponding lamp housings.
Modulation slide or phase contrast slide*
The modulation slide or phase contrast slide is
part of a constrasting method, either Integrated
Modulation Contrast (IMC) or phase contrast.
The same slides are used for the S 55 and S 90
condensers, however, with different phase
rings.
If no phase slide or modulation slide is used, it is
also possible to insert an empty slide into the
corresponding holder on the condenser.
IMC modulator*
For the Leica Integrated Modulation Contrast
technique, the IMC modulator is provided in the
microscope stand. (→ p. 47 Operation of IMC).
In the standard version, all DM IL microscopes
are equipped with an empty slide.
