Many large scale particle detectors use photons as their primary event detection method, usually detecting numbers of photons and their arrival times. Photons also carry information about an event through their wavelength, polarization, and direction, but often little to none of this information is utilized. In this talk, we introduce the “dichroicon,” a Winston-style light cone comprised of dichroic filters which allows detectors to use the wavelength information encoded in photons. The dichroicon functions as a spectral photon sorter and has a broad range of applications including correction for photon dispersion in large scale detectors, the discrimination between Cherenkov and scintillation light, and new handles on particle ID. This talk will present results that quantify the dichroicon's ability to separate scintillation and Cherenkov light, as well as present simulation results illustrating the impact of dichroicons in next generation neutrino detectors, specifically THEIA.
