Request InfoPicoQuant GmbHPicoQuant GmbH has introduced version 1.2 software for use with its HydraHarp 400 time-correlated single-photon-counting system. The program provides a real-time correlator for fluorescence correlation spectroscopy (FCS) that calculates two autocorrelations and the cross correlation between two photon streams simultaneously. The new release supports Windows 7 and the latest HydraHarp hardware, with up to eight timing input channels. Each channel produces 1-ps resolution at a processing rate of 12.5 million counts per second per channel. All channels operate independently but with a common...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2023 IssueSingle Photon Counting UnitThe PicoHarp 330 from PicoQuant is an event timer and time-correlated single photon counting (TCSPC) unit made for scientific researchers and professionals in photonics and related disciplines....Promoted Content February 2024 IssueSee3CAM_50CUG: High-Sensitivity Medical Camera for Noiseless Imaginge-con Systems See3CAM_50CUG is an all-in-one camera solution for medical applications.
