The radiation
$
is generated by the Xenon-Lamp
#
.
The radiation
$
is filtered through an optical filter
"coated quartz dish"
%.
Note!
There are optional filters (see Chapter 5, „Accessories’)
available for various spectral distributions (see chapter.
4.1.3, „Spectral distribution with additional filters“).
• The UV-component of the radiation, that is directed
upwards, is reflected on the specimens
!
by the
mirrors
&
that are placed above the Xenon lamp
#
.
• The components of the non-dangerous IR-radiation
(heat radiation) are absorbed by an absorber, and re-
moved out of the equipment via the air circuit of the
Xenon lamp.

• The coolant air of the test chamber
!
is sucked in-
ward on the rear side of the equipment (see chapter
3.3, „Rear side of equipment“) through an air filter,
flows through the test chamber and exits at the bot-
tom of the equipment
"
.
• The coolant air of the Xenon lamp
#
is drawn in on
the rear side of the equipment (see chapter 3.3,
“Rear side of equipment”) through an air filter, flows
through the Xenon lamp compartment and exits again
on the exhaust opening on the rear side
$
.
NOTE!
During continuous operation, the hot air emitted by the
air cooling system results in a continuous change in the
labboratory climate.
