Hi, thanks for reporting. For the first and second, did you have the "vertical" checkbox checked? Perhaps for one but not the other?
For the calibration itself, you need to choose a cross section that intersects the spectrum at your desired height. Then there will be a marker for cross section on the image. As it is now, it's sampling the top row of pixels. I'm going to create a feature request that for vertical images, it uses the middle row of pixels. That may work better for folks using a foldable spectrometer:
Is this a question? Click here to post it to the Questions page.
"vertical" checkbox (of SpectralWorkbench upload page) checked in the three tests.
Now, rotating and cutting the test 1 image, I did two uploads with:
...see You that the result of B2 and G2 should be close to 435.83nm and 546.07nm, but these are my results:
Test 4: B2 = 1198.37nm and G2 = 1599.49nm
Test 5: B2 = 113.13nm and G2 = 514.11nm
I think I can get two conclusions, that is, I have two variables influencing my results:
The score remains the same regardless of the length of the image. Maybe the DVD I used is not appropriate for the spectral kit 3.
The length of the image modifies the wavelength. I'm in trouble with the dimensions.
I bought "Diffraction Gratings 1000 line/mm" but not yet received.
