Optical properties luminous solids

Light Transmittance (luminous transmittance, light transmissivity) The ability of a material to pass incident light through it, whether specular or diffuse. ASTM (www.astm.org) prescribes several tests of this property in plastics. Transmissivity is the ratio of the intensity of the transmitted light to that of the unreflected incident light. See also Opacity. (Fox AM (2001) Optical properties of solids. Oxford University Press, UK)... [Pg.427]

Luminance is the intensity of emitted radiance per unit solid angle and frequency. It is sometimes called spectral radiance, or radiant flux. Emissivity is a property of a sample measured at standard conditions. The sample must be thick enough to be both optically opaque and smooth [63]. In the case of a perfect black body, the sample cannot be reflective. This property is not composition or geometry dependent even a heated pinhole cavity will show a good black body curve. [Pg.104]
