Justice League spectral analyzer

The Justice League spectral analyzer is a device in the Hall of Justice that the Justice League use to scan objects (such as paper) to see if any trace particles of something can be found on it, to give a clue were it might have came from.

During the Cosmic Crisis, Batman used the device to scan a piece of paper that had a message from Marvin written on it. The spectral analyzer was able to find traces of coral and volcanic ash.
