The Sloan/SDSS filter passbands are approximately disjoint.
This offers (in theory) the opportunity of imaging in several of the
bands simultaneously, via dichroic beamsplitting.
(One could do the same in the non-disjoint Johnson/Cousins
passbands by accepting a two-way split betwen disjoint pairs,
i.e. between B and R or V and I.)

ANDICAM is an example of simultaneous multi-band imaging, doing
a two-way split between the IR and "visible".

If you have experience with splitting within the visible, particularly
using the Sloan passbands, I would be interested in hearing
about your approach and results.
