com and entering available or desired data for one of more of the following criteria: product code; product name; color description; 1* a* b* color space value; solar reflectance (TSR/SRV); thermal emittance (TE); solar reflectance index (SRI); and Energy Star and/or CRRC listing.
The light reflectors were made applying this coating material to an aluminum substrate; their diffuse reflectance was measured and found to vary from 97% to 100% for 0.
In mathematical terms, these programs very coarsely sample the spectral power distributions of the light sources and the spectral reflectance and transmittance distributions of the surface materials.
Our objectives were to: (1) describe reflectance characteristics of the Golden-winged Warbler throat patch, and (2) ascertain if these characteristics correlated with indices of male quality, which would suggest a possible signal function.
A high reflectance over a broad spectral range of 250-2500 nm increases optical efficiency.
The medium and coarse resolution satellite systems, such as MODIS (Moderate Resolution Imaging Spectroradiometer), produce almost continuous data over the whole Earth and thus the information on reflectance seasonal changes at a coarse scale and in large territories is relatively well represented.
The Evolution 600 offers accessories for analyzing solid samples, including a diffuse reflectance accessory, a VN absolute specular reflectance accessory and a solid sampling accessory.
where Rs is an average value of absolute reflectance values as measured on a surface of the coating layer in a wavelength range of 2400 to 2000 nm.
