Thanks for your question. When you have multiple spectrometers connected to ENLIGHTEN, the software will display the data in one graph on the main acquisition screen, such that you can see all the data at the same time. The spectra are by default going to be offset from each other to some extent, as we do not “stitch” or concatenate data in our software. In your example of a VIS and NIR device, the two spectrometers would have different sensor types (Silicon and InGaAs) and correspondingly different gains, well depths, and quantum efficiencies. There would be a step difference in the arbitrary y-axis counts of these two sensors relative to each other. When you save the data from these units, the data will be saved in individual files so that the identifying header information is maintained for each unit with info such as serial number, TEC temperature, integration times, etc.. For this stitching and other advanced data work, our customers typically post-process their data in a secondary analysis program, such as R, Matlab, or even just Excel. The reason for this is they wish to maintain the original raw data, and any technique to merge spectra from two different units will create some loss of data fidelity. In other words, feedback from the largest portion of our customers is they prefer to do spectral stitching themselves and know exactly what is happening with the data.

That's the great thing, Keeya - this software is free, and it works with all of our spectrometers! You can download it from our ENLIGHTEN software page at wasatchphotonics.com/product-category/software/

Great news! Our ENLIGHTEN software is free, as are our SDKs for writing your own spectral acquisition code in a variety of programming languages.
