Emissivity is an indicator of how much heat a material can absorb, and if conditions are right reradiate to a cooler body. The emissivity scale ranges from 0 to 1, where 1 is a theoretical black body that absorbs 100% of the energy to which it is exposed and 0 is a perfect reflector that absorbs no energy.

WebObtaining total hemispherical emissivity at high temperatures is difficult. Typically only directional data at specific viewing angles (normal, near normal or at an angle between 45 and 60 degrees) is generated at high temperatures. The calculation of hemispherical emissivity from the directional emissivity is an approximation. WebAn excellent coating for MWIR and LWIR with extremely low reflectance at Acktar's website, ...
