You can use a previous fluorescent bulb spectrum from the same spectrometer to calibrate this spectrum, as long as the device has not been modified.
First, choose a recent calibrated spectrum; the most recent is selected by default:
You must be logged in to copy a calibration.
Use the in-development Spectral Workbench API to run scripts (macros).

The macro publishing and sharing system is under construction. To share your macros, please email the mailing list at plots-spectrometry@googlegroups.com -- ideally with a link to your macro on gist.github.com and it will be added.
You can calibrate with a clear fluorescent spectrum like the one shown here. If the current spectrum is not usable, you can record a new one, and if you do not change your spectrometer, you can use the calibration for subsequent spectra.
First, click on the highest peak of the middle blue band:
To generate data, we look at the brightness of one slice of the image. Here, click on the image to choose which row to sample from.
You must be logged in to choose a sample row.

Nice and clear! I think though that you might be getting blue light from the little LED in the camera. We've discovered that it's a good idea to clip it out or cover it up.
What was your mobile cell type? Did you have any specialized settings to get the quality?
Hi Gents, thanks for the comments, however I'm sorry to disappoint, I don't yet have a spectrometer, I am totally new to this and wanted to check how the upload image feature worked before I purchased a kit so I just saved an existing image from the spectralworkbench site called Plastic to my desktop and then uploaded it.
How do I delete it from here, I can't seem to find a way to delete?
Also do any of you know if this kind of spectography can be used to identify plastic types for scrap recycling, example PET, HDPE, LDPE, PP etc?
I hope it can be used like that -- i think it's worth doing some VIS/NIR full spectrum absorption tests of each type. Where was the original spectrum?
Hi Warren The original spectrum was called "Plastic" it's there on the spectralworkbench.org site, I just took a screenshot and re-uploaded the same thing to test the uploading feature.
