Overview and concept of LT-FCM. (a) Schematic drawing of the optical setup of the LT-FCM. Optical components are indicated: (D)M refers to (dichroic) mirrors, BP/LP to band pass/long pass filters, ND to the neutral density filter, and BS to the beam splitter. The detection channels are LT (lifetime), SSC (side scatter), FL1/2 (fluorescence). Details on the optical components can be found in the Supplementary Information, Table S1. (b) Block diagram of the novel signal processing unit for single photon lifetime analysis for LT-FCM. (c) Visualisation of lifetime encoding with beads: Each code should exhibit similar spectral properties but differ in the decay kinetics from the other codes.
