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 structures.
This parameter is referred to as “dullness”.
