    Is there a factory determined RGB Ratio for the STXL-11002? If not, is there a utility to determine this? Thank you. Alan

    Hi Alan, I'm just another customer. Assuming you have a mono sensor, it's dependent on the filters you have, as well as on the quantum efficiency of the chip at different wavelengths.
    You can find data on the QE (quantum efficiency) here:

    You'll also need to know the transmission characteristics of the filters you have.
    Best to calibrate on a daylighted 18% grey card or star like our sun.
