Correlation timing electronics convert intensity data into correlation functions and diffusion coefficients, which yield hydrodynamic radius via the Stokes-Einstein equation. Multiangle DLS measurements provide robust size distributions for polydisperse samples using Cumulant or CONTIN analysis methods.Photon Number Resolution: Background and State-of-the-Arthttps://www.swabianinstruments.com/zh/knowledge/concepts/pnr-background-state-of-the-art/Mon, 01 Jan 0001 00:00:00 +0000https://www.swabianinstruments.com/zh/knowledge/concepts/pnr-background-state-of-the-art/Photon Number Resolution (PNR), the ability to distinguish how many photons are impinging on a single photon detector within a defined time window, can be achieved through pseudo-PNR, where photon numbers are statistically inferred, or intrinsic PNR, where photon numbers are measured directly from the detector signal.Time-Correlated Single Photon Counting (TCSPC)https://www.swabianinstruments.com/zh/knowledge/concepts/tcspc/Mon, 01 Jan 0001 00:00:00 +0000https://www.swabianinstruments.com/zh/knowledge/concepts/tcspc/Time-Correlated Single Photon Counting (TCSPC) is a technique that measures the precise arrival times of individual photons emitted by a sample following an excitation with a pulsed light source.
