Fluorescence is delivered from the sample to the detectors via 5 fiber optics corresponding to the excitation laser. The fibers terminate in fixed-alignment assemblies known as trigons and octagons. Long-pass dichroics pass the signal around the assembly, extracting longer wavelengths first, and proceeding to shorter wavelengths. Detectors within a trigon or an octagon are labeled alphabetically, with detector "A" detecting the longest wavelength and detector "C" (trigon) or "H" (octagon) detecting the shortest.
