Filter system

The XENOTEST BETA is used to simulate the so-
lar or global spectrum with filtered xenon lamp ra-
diation. To realise the various standards and test
specifications a XENOCHROME filter system is
at your disposal.
The XENOCHROME filter system (fig. 18) consists
of a filter lantern (2) with three absorbers (3)
staggered by 120°, and 10 filters (4) with the
corresponding outer cylinder (5).
A) XENOCHROME 270 (I) with quartz glass
cylinder,
B) XENOCHROME 300 (II) with special UV
glass cylinder (Suprax),
C) XENOCHROME 320 (III) with special UV
glass cylinder, (Suprax).

Useful lifetime:
The XENOCHROME filters are very resistant to
ageing, and their recommended lifetime is 25,000
hours. The filters are exchanged as complete set
and for distinction are marked at the lower filter
end with the numbers I,II,III or 270, 300 und 320.
Different irradiance values can be obtained by
varying the optical filter system (see figs. 19 and
20).
Path of radiation:
The fraction of UV and light radiation which come
into contact with the coated filters pass through
the outer cylinder towards the specimen level, while
the IR-radiation parts are reflected and directed
on to the black metal absorber which absorbs them.
The air flow along the xenon lamps and the
absorber plates in the optical filter system
dissipates the heat.
