FS5 Spectrofluorometer
FS5 Spectrofluorometer
The FS5 Spectrofluorometer is a compact, high-performance benchtop system designed for the comprehensive characterisation of fluorescent and phosphorescent samples. Since its launch in 2013, the FS5 series has become a trusted solution for fluorescence research, contributing to thousands of scientific publications worldwide.
The FS5 v2 Spectrofluorometer is the latest evolution of the FS5, offering enhanced performance and expanded capabilities to meet the growing demands of modern photoluminescence spectroscopy.
Equipped with top-tier optical components, photon-counting sensitivity, and fluorescence lifetime capabilities, the FS5 excels in both rapid routine analysis and sensitive research tasks.
This compact benchtop instrument adapts seamlessly to your needs, offering flexibility with multiple source and detector configurations without expanding its footprint. As standard, the FS5 v2 includes a photon-counting PMT detector for visible-range fluorescence spectra and an absorption detector. It can be easily upgraded to perform NIR measurements up to 1650 nm, time-resolved fluorescence or phosphorescence, photoluminescence quantum yields, and anisotropy.
