Incident-light fluorescence illumination*
To obtain a brighter image for incident-light
fluorescence applications, the Leica DM IL
microscope is preferably fitted with mercury
and Xenon gas discharge lamps but can also be
operated with a 12 V/100 W halogen lamp.
Performance data of lamp housings
106 lamp housing*
The 106 lamp housing is fitted with a 12 V/100 W
halogen lamp. The lamp holder can be centred
in the x/y plane. The aspherical collector can be
focused. The 106 lamp housing does not have a
reflector but is fitted with a diffuser disc and a
heat-absorbing filter.
106 z lamp housing*
Same as 106 lamp housing but with centrable
and focusable reflector and 4- to 6-lens col-
lector. A quartz collector is available on request.
The following lamps can be used, each with the
corresponding special lamp holder:
– Halogen lamp 12 V/100 W
– Hg ultra-high pressure lamp 50 W (AC)
– Hg ultra-high pressure lamp 100 W
(DC, stabilised)
– Hg ultra-high pressure lamp 100 W
(DC, stabilised Type 103 W/2)
– Xe ultra-high pressure lamp 75 W
(DC, stabilised)

107/2 lamp housing
The shield connection of the lamp housing is
screwed down to the equipontial bonding point
on the 12 V/100 W power unit. This lamp housing
for incident-light and transmitted-light operation
has a 1-lens fixed collector and a fixed 12 V/
100 W lamp.
Note:
The LH 105 lamp housings have been replaced
with the LH 106 lamp housings. However, they
are compatible to the LH 106 lamp housings and
can also be used.
