Dear all, I'm building a photoluminescence system, and it seems that because of the optical component's response across my wavelength of interest I'm getting several stray peaks (see picture) [img]http://www.originlab.com/ftp/forum_and_kbase/Images/PL.JPG[/img] I know that the correct data is supposed to be a skewed Gaussian , and the spectrum that I'm getting here is the skewed Gaussian multiplied by the system's response. I tried to eliminate the peak by using either smooth or FFT filter, but it seems that if I don't set the parameters properly it will become a problem later when I need to do peak fitting. Does anyone have any suggestion on what I can do to eliminate the system response using Origin? Currently I'm using OriginPro 2015. Any help is much appreciated.
