    Hello,

    is it possible in any configuration to get the SWIR and VNIR signals in parallel?

    Kind regards

      Andreas,
      Unfortunately there is no way to sync up the two images because the cameras for each have different imaging sizes. The SWIR camera has a smaller field of view.
      But do you mean the joining just the spectrum in the graph?

      Thank You,
      Jamie

      Hello Jamie,

      I want to have the whole spectrum from 400 nm to 1700 nm. I am interested in signals that appear in both ranges. So, e.g., when one spot on the glas slide gives a signal at 520 nm, I am interested in the signal of the same spot at for example 1300 nm.

      Thank you in advance

      Andreas

        Andreas,
        You may be able to take a spectra from the VNIR image and a spectra from the SWIR image and overlay them in the same plot but I am not sure.
        I will ask!
        Thank You!

          Andreas,
          Because the spectral resolution is slightly different for each system it does not seem possible to combine the VNIR-SWIR spectra in ENVI.
          But this may be possible to do in Excel. You can export any spectra in ENVI as ASCII data.
          In Excel you can combine the 2 spectra and plot them.
          Let me know if this works as I have never tried this!
