Calibration

  • model: (i.e. STS, etc...)

Question

I intend to use spectra from a STS-Vis. This device is spectrally calibrated (in intensity). Where does the calibration is done? Inside the device? In OceanOptics's software?
This is important because I need to use the calibrated version of the spectrum and I then I want to know if python-seabreeze will meet my requirements.

Thanks

Hi @ColinBrosseauAlgolux

I assume when you say that your device is callibrated you mean that an irradiance calibration is stored on your spectrometer?
python-seabreeze's cseabreeze backend let's you read the calibration from the device. But you'll have to write the bit of code that applies the calibration to a measured raw spectrum yourself.
(If I recall correctly, it's just multipling or dividing by the calibration array, so it should be very easy.)

Cheers,
Andreas 😃

Hi @ap--

Thanks for your answer. As long as I can get the calibration from the device it's OK.

Many thanks,
