Black light-absorbing

The sample is a single sheet o1 paper backed by black, light-absorbing surface. 

Spray one half of the target sample with flat black (light absorbing) paint, or cover it with black masking tape or some other substance of known high emissivity. 

Etched beryllium light absorbers are somewhat more robust than Martin Black 54 but, as shown m Fig. 10, are meffective above certam wavelengths. Moreover, both beryllium and aluminum are sensitive to envuonmental degradation and may degrade thermally due to their low melting temperatures. 

Light-absorbing Carbon carbon particles in the atmosphere that absorb light. Black carbon. 

Light-absorbing pigments differentiate rod cells for black-white vision and three types of cone cells for color vision 807... 

The most commonly used black pigments are carbon blacks. In addition to being efficient light absorbers, some varieties of these small-particle-size materials impart electrical conductivity and thixotropy to paints. The... 

Ultraviolet Light Stabilizers. Both titanium dioxide and carbon black are strong ultraviolet light absorbers and effective in protecting the PVC. For ultraviolet light absorption in transparent PVC oi foi impiovement of pigmented systems, various derivatives of benzotnazole are used. 

Awareness of the obvious overhead heaters, radiators, drafts, leaking roofs, light/heat/cold from windows, metal buildings, black bodies (absorb heat).
