TABLE 6.6
GUIDE TO EMISSIVITY VALUES FOR TARGET MATERIALS IN THEIR “USUAL” FORM
ARRANGED BY CLASSES OF MATERIAL
INSTRUMENT SERIES:
MODLINE 4, Series 46
SPECTRUM: 2.0 to 2.6 microns
All specimens in this table are in their common physical form . These materials have negligible transmittance
τ
in their common form. Any difference between the listed Emissivity
ε
and a “perfect” Emissivity of 1.0 is due
to Reflectance
