A micro-wave ray is a fictional item featured in comic book titles published by DC Comics. It is part of DC's Pre-Crisis Earth-One continuity and relates to the Superman family of comic book titles.
The micro-wave ray was a technological device that could alter the size and density of a volume of matter, reducing it in size. It was developed by Superman and used in the Fortress of Solitude. The ray's primary purpose was to reduce Superman and others in size so that he could visit the bottled city of Kandor.
Supergirl once used the micro-wave ray to defeat a member of the Superman Revenge Squad named Blymm, who had infected her with Virus X. [1]
