An emulsion under test must always be exposed to light of the correct wavelength and wavelength range.
Sequential systems are defined by a field of view, wavelength range and surface data.
The copper spectral overlapping interference for lead by full wavelength range direct reading ICP-AES:An experimental study
It is an effective method for the control of sensitivity in different wavelength range that desensitizing dye is added to the spectral sensitized emulsion.
