Operation
The table below lists the modes of operation that should be used for particular samples.
Transmittance Single areas of thin solids, fibers and films. The optimal aperture
range depends upon the detector type, as follows:
MCT detector: Between 10
µ
m and 100
µ
m.
DTGS detector: Between 50
µ
m and 200
µ
m.
InGaAs detector: Between 10 µ m and 200 µ m.
Reflectance Single areas of coatings and thick solids. The optimal aperture
range depends upon the detector type, as follows:
MCT detector: Between 10
µ
m and 100
µ
m.
DTGS detector: Between 50
µ
m and 200
µ
m.
InGaAs detector: Between 10 µ m and 200 µ m.
With ATR objective Thick, non-reflecting samples.
NOTE:
In general, the larger the aperture setting, the better the spectral quality. Sample
sizes may be larger than the maximum aperture sizes given in the table above.
