"This prismatic scanner is just a more powerful version of the camera's filter."
Barry Allen to Mirror Iris West-Allen[src]

A prismatic filter is a device that can detect mirror duplicates. It is an upgraded version of the filtering technology in Kamilla Hwang's camera.

History

At some point, McCulloch Technologies developed the device as part of their experiments.

In 2020, the prismatic filter came into possession of Eva McCulloch, who gave it to her mirror duplicate of Iris West-Allen. When Barry Allen suspected that "Iris" was not who she seemed, he used the prismatic filter to reveal her true form. However, Eva had reprogrammed the device so that it would "reveal" Barry as the duplicate instead. He was locked up by Cecile Horton and Nash Wells, but later released.[1]
