Emissivity as viewed on the Fuji & Co Piezo Science page
A brief explanation of the topic of emissivity, that gets into the concept of spectral emissivity... a little. It deals with the total emissivity used in radiant heat transfer, but the basic concepts apply at any wavelength. Visit http://www.fuji-piezo.com/emissivi.htm online to read their explanation.
Ultra-thin perfect absorber employing a tunable phase change material
New device hides, on cue, from infrared cameras November 26, 2012 Tunable material developed at Harvard boasts nearly 100% absorption on demand Cambridge, Mass. - November 26, 2012 - Now you see it, now you don’t. A new device invented at the Harvard School of Engineering and Applied Sciences (SEAS) can absorb 99.75% of infrared light that shines on ...
Reflectivity of Mineral Powders

Noncontact multiband emissivity measurements
Proc. SPIE 5124, 240 (2003); doi:10.1117/12.517121 Conference Title: Optoelectronic and Electronic Sensors V Conference Chairs: Wlodzimierz Kalita Abstract Adam Mazikowski Gdansk Univ. of Technology (Poland) During last decade an increasing interest in passive multiband systems for temperature measurement was noted. However, recent studies showed that multiband systems are capable of producing accurate results of non-contact temperature measurement only in limited number ...

MODIS -Moderate Resolution Imaging Spectrometer UCSB Emissivity Library – (an updated link)
The MODIS (Moderate Resolution Imaging Spectrometer) UCSB Emissivity Library is a collection of Emissivity measurements of natural and man made materials that may be used as a source of spectral emissivities at the component level in the TIR BRDF models to calculate the scene emissivities in the split-window channels to be used in the LST ...
Emissivity of Human Skin in the Waveband between 2 & 6 micrometers
From a Nature Article of the same title: By DAVID J. WATMOUGH & R. OLIVER, Department of Radiation Physics, Churchill Hospital, Oxford. Citation: Nature 219, 622 - 624 (10 August 1968); doi:10.1038 Abstract: The emissivity of human skin epsilon(lambda) in the range 2micro to 6micro has recently assumed considerable importance because of the increasing medical use of infrared scanners ...
