The right way to do that would be with FTIR or Raman spectroscopy, and this sensor is capable of neither.
At best, this is an ersatz replacement for the tunable filter on a hyperspectral imaging system. There are some advantages (off hand, acquisition rate is a big one) to a more diverse mosaic filter, but other than in using QDs as the actual filter medium, this idea is not at all new.
