Whether you are studying photophysics, photochemistry, biophysics, biochemistry or semiconductor physics, the FLS920 will enable you to reliably and accurately measure luminescence in either steady state or lifetime modes. A wide range of digital and analogue detectors allow you to choose your spectral coverage. Additionally, the FLS920 has a large sample chamber that can house a variety of sample holders and accessories.
Advanced software both controls the instrument and allows analysis enabling you to design your experiment from your desktop, watch your profiles build live on screen and comprehensively manipulate and analyse data.
The FLS920 can be configured to include one, two or three operational modes. The available options are a steady state module, a time-correlated single-photon counting (TCSPC) module for lifetimes between 10ps - 50µs and a multi-channel scaling (MCS) module for lifetimes between 400ns – 10s. Fluorescence lifetimes are typically measured by TCSPC, whereas phosphorescence lifetimes are typically measured by the MCS.
The addition of a combined microscope and imaging camera to the FL920 further enhances the capability, allowing measurement of specific points within a sample and for imaging with monchromatic exciation/illuminaton.
Liquid nitrogen and liquid helium cryostats are available as part of the range of temperature-controlled accessories for the FL920. Fully field retrofittable, these cryostats allow fluorescence measurements and temperature maps to be made over the temperature ranges 77 - 300K and 4.2 - 325K respectively. Versions with an upper temperature of 500K are also available.
