Hello Koji,

as promised, I send you the results of the analysis of your last spectrum. I determined the calibration parameters from the Na-lines. After subtracting the background, I transformed all ...

Hi Bill,

very nice spectra Smile It looks that you have improved your calibration. The background (baseline) seems to be correct now. It was worth taking your time. Unfortunately not many spectra fro ...

Hi,
I have to be more precise: I exchanged the Logilink 0001A with another one 0001A which I knew was working because I suspected a faulty video grabber. Both are working on another computer.
