definition |
UV intensity (RUV) |
percentage reflectance (%) of UV reflection band |
VIS intensity (RVIS) |
percentage reflectance (%) of VIS reflection band |
total intensity (Rtotal) |
area under reflectance graph (from 300 to 700 nm) |
UV hue (λ(RUV)) |
spectral position of UV band peak: wavelength (nm) of maximal reflectance in UV range (300–400 nm) |
VIS hue (λ(RVIS)) |
spectral position of VIS band peak: wavelength (nm) of maximal reflectance in VIS range (400–700 nm) |
band separation (λVIS–UV) |
wavelength difference (in nm) between UV hue and VIS hue |
