Related to dominant wavelength: Complementary wavelength, excitation purity

wavelength, dominant (of a colour stimulus, not purple) 

Wavelength of the monochromatic light stimulus that, when combined in suitable proportions with the specified achromatic light stimulus, yields a match with the colour stimulus considered. Note: When the dominant wavelength cannot be given (this applies to purples), its place is taken by the complementary wavelength (CIE). See complementary colour.

The form of regression function of this dependence is L* = exp(-[k.sub.L]d*[x.sub.L]), where [k.sub.L] is the luminance attenuation coefficient, which generally depends on LED colour (dominant wavelength) and fog type, and [x.sub.L] is the fog layer thickness (2 m in this case).
That is, it has been habitual in the scientific-technological community to consider hue perception as strongly determined by dominant wavelength (or chromatic angle.
In addition to its inherent value, this information makes obvious that the colourimetric specification of a basic category can not be made only in terms of dominant wavelength, but must also include lightness and saturation.
The following parameters will be used to perform the colourimetric evaluation: dominant wavelength ([[lambda].sub.D]), purity (p), reflectance (R), CIEu'v' saturation, and CIEu'v' chroma.
In this approach, the WDM interleaver (WDM IL) is used after the DAM to separate the generated dominant wavelengths [16].
Recent advances in materials and manufacture have resulted in the commercial availability of light emitting diodes (LEDs) with narrow spectral distributions, high power, and dominant wavelengths spanning the entire visible spectrum (2).
