The DIRC-principle (detection of internally reflected Cherenkov light) allows a very compact approach for particle identification detectors. The PANDA detector at the future FAIR facility at GSI will use a Barrel-DIRC for the central region and a Disc-DIRC for the forward angular region between 5 and 22 degrees. It will be the first time, that a Disc-DIRC is used in a high performance 4π detector. To achieve this aim different designs and technologies have been evaluated. So far two prototypes have been built and were successfully tested during beam times at DESY and CERN. Their results will be presented. An overview of the technical challenges and the evolution of various design options of the PANDA Disc DIRC detector is given and the capabilities of this novel detector concept will be highlighted.
