Request InfoPicoQuant GmbHPicoQuant GmbH has released Version 3.3 of its FluoFit multiexponential fluorescence decay fit software for PCs. Supporting Windows 95 and up, it implements an iterative reconvolution of the instrument response and the observed fluorescence decay with nonlinear error minimization. Parameters and options can be manually adjusted; the fit limits can be adjusted by graphical sliders. User preferences can be stored and retrieved, and numerical and graphical results can be printed and saved for reference.See full productRelated content from Photonics MediaPHOTONICS HANDBOOK ARTICLESPhotonics HandbookFluorescence Lifetime Imaging: Choosing the Best ApproachThe term fluorescence is often applied as a synonym for photoluminescence, although luminescence actually covers fluorescence and phosphorescence.
