13 IR source
14 EDL
The radiation emitted by an IR or UV/EDL
source passes an adaptor cell, widening the
beam to completely ll out the analysis cell´s
diameter. At the opposite side of the cell,
another adaptor cell is installed to reduce
the beam to the diameter of the opening in
the chopper.
The detectors are installed at the rear side
of the chopper.
As pyrodetectors are not as
frequency selective as gas detectors, an ad-
ditional lter has to be installed when using
pyrodetectors, limiting the bandwidth of radi-
ation passing the chopper.
