Description Returns the human eye's scotopic response at a given wavelength.
Syntax r = Scotopic ( wavelen )
Parameters r (Double) The scotopic response at the given wavelength.
wavlen As Double The wavelength in microns.
Remarks This function computes the human eye's scotopic response value at the given wavelength in microns. The scotopic response is the relative response of the average human eye at low (or dark adapted) illumination levels.
