2.2.2 Wavelength and Scales
Standard scales for wavelength are the classic SW and LW and the modern W
a
..
W
e
.
The “classic” scales have following ranges:
• Shortwave (SW) = 0.3 .. 1.2 mm
• Longwave (LW) = 1.2 .. 12 mm
The “modern” scales have following ranges:
• W
a
= 0.1 .. 0.3 mm
• W
b
= 0.3 .. 1 mm
• W
c
= 1 .. 3 mm
• W
d
= 3 .. 10 mm
• W
e
= 10 30 mm
These scales (and many more) can be activated in the instrument.
2.2.3 Measurement of Dullness
Structures smaller than 0.1 mm influence visual perception, therefore the wave-
scan uses a CCD camera to measure the diffused light caused by these fine struc-
tures.
This parameter is referred to as “dullness”.
