1. A device comprising:
a detector surface configured for supporting biological or chemical samples;
a sensor array comprising light sensors and light guides;
wherein the light guides receive excitation light and emissions signal light from the detector surface, wherein the light guides extend toward respective light sensors of the sensor array and comprise filter material, and wherein the filter material comprises a dye having a transition metal, and wherein the transition metal has an absorption spectral profile overlapping a fluorescence emissions spectral profile of the dye.
