Everything that concerns the open-source Raman spectrometer
Hi, I am trying to calibrate the spectrometer but I am running in some trouble. I have the HG-2 calibration lamp from Ocean Insight. But when I try and calibrate the spectrum received only shows limited spectral lines. Is there any possibility to manually set the wavelength of specific spikes? The software does not handle the big gap between the spikes.
Attached should be the emission lines from the light source, yet the other image is what is measured on the sensor. Through some analysis, the leftmost emission line should be the one at 546.074nm as this can be filtered away by the dichroic lens. Is there any way to manually set the emission lines on dedicated emission lines?
I think I finally got to a point where I calibrated my spectrometer, now for a primary test with Ethanol I do get a result as follows. This does not look promising if I compare it against the data from the performance page of the starter edition on the website. Any idea why it is so different?

could you click on the icon with the red/green/yellow blocks (win95 defragment icon) and send a picture ? I'd like to check centering of the beam. If you can take a full screen image (full roi) with spinview that would also help.
