Zeiss Optoplex NGQ files may have a row with explicit wavelength values – or not.
If wavelength information is present there is an empty line before and after the row with wavelength values. We rely on the assumption that the generated wavelength values are equidistant.
In the case of missing wavelength information we count the number of spectral points. It is assumed that the first one belongs to a wavelength of 380 nm, and that the difference between neighbored points is always 5 nm.
Our software can now import NGQ files both with and without wavelength row.
