Call for data for survey of CCD spectrometers.

Do you have a CCD spectrometer?

If you do, would you please collect two fluorescent lamp spectra and send me the data in ascii format.

One with the 546nm just a little bit below saturation and another at about 1/4 of that intensity.

Thank you.

Hi, in case you are interested, I am posting similar topics, but with a lot more detail on reddit (as "u/Instrumentationist"). And of course, there is the "readme" on github,

github.com/drmcnelson/TCD1304-Sensor-Device-with-Linear-Response-and-16-Bit-Differential-ADC

TCD1304 or S11639-01

Why you might choose the TCD1304 over the S11639-01 in most instances.

1) TCD1304DG $18 on Digikey, vs $200 to $450, and not found even on octapart.

2) Response spectrum, S11639-01 left, TCD1304DG right - self explanatory.

Linear reproducible response in CCD spectrometers.

Hi, the repo for the TCD1304 with linear response is recently updated and now pretty much complete. There will be one more addition on "carry over", and then that's it.
