The tiny, relatively inexpensive devices could be used for customized astronomy research

Summary:
     Researchers are designing new ways to make spectrometers that are ultra-small but still very powerful, to be used for anything from detecting disease to observing stars in distant galaxies.
 Seems a clever way to do, see picture of it here:

I cringe at the meaningless and incongruous comparison of a
resolution figure with the width of a hair. Anyway, better
resolution and smaller size inevitably go at the cost of
sensitivity. I don't see these things being of any use in
astronomy, although they may be useful in setups where the
light intensity is plenty.
