Lens filtration

[Kerrowman]

Hi there,

I have been using my Mavic Mini for photogrammetry to create 3D models of archeological sites for several years and now want to try some multispectral imaging using filters over the camera lens.

Of particular interest are the red and near-infrared parts of the spectrum for changes to chlorophyll in vegetation.

To arrange the right filtration I need to know what the camera lens already filters out e.g wavelengths below 350nm and above 750mm (my guesses) and similarly for any filters used over the sensor itself.

Does anyone have any information on this as DJI has so far failed to respond?

Thanks

You might need to upgrade to a different drone maybe.

For cost reasons I am trying to avoid that and filtration options are a valid route to multispectral imaging - but it depends on what the lens and any sensor filters are already doing, or not - hence my question.
