camSPECS
In order to measure the spectral response of a camera, we have the camSPECS spectrometer. It uses 56 filters going from 380nm-1100nm.
If you are using this device for the first time, we recommend you to follow this step-by-step tutorial.
The original instruction manual can be found here.
Update: We had the whole unit recalibrated as there were some errors at certain wavelengths. You find the latest software along with the latest recalibration files here.
Measured Spectral Responses
You find a list of measured spectral sensitivities for different camera/filter pairs.
For your convenience, you can also download a zip-file for a specific camera model to get all measured spectral sensitivities along with the plots:
