Regarded as a complete laboratory in one instrument, the FLS920-st offers ultimate sensitivity with high spectral resolution and excellent stray light rejection
The FLS920-st is a modular, computer controlled L - geometry spectrometer for acquiring steady state luminescence spectra, time resolved fluorescence spectra and the associated fluorescence decays in the ultraviolet - visible - near infra red spectral range with single photon counting sensitivity. The steady state mode uses a single photon counting, fast photon counter scalar PC plug-in card for steady state measurements. This card operates with count rates up to 100MHz . For fluorescence lifetime acquisition the system employs the technique of Time Correlated Single Photon Counting: this technique is widely accepted to be the method of choice for maximum sensitivity, dynamic range, accuracy and precision. The sensitivity of the system guarantees a signal to noise ratio of 6000:1 for water Raman spectrum measured with excitation at 350 nm, emission at 397 nm, with a 1 second integration time and 5 nm spectral bandwidth.
The configuration of the FLS920-st consists of the following hardware:
In keeping with the modularity of the FLS920-st spectrometer, the F900 advanced software is a user friendly package. Irrespective of the system configuration and accessories, the F900 software provides the user with complete control. Measurement set-up and data acquisition is made through a transparent menu system and the measurement modes within the software reflect the system configuration by means of a simple operating environment. Control of the hardware settings on both the TCC900 and the PCS900 data acquisition cards are easily accessed through the F900 software.
The modular design of every spectrometer provides maximum flexibility to meet the requirements for a wide range of applications. We offer a wide range of accessories for the FLS920-st together with a range of standard upgrade options for this spectrometer.
The FLS920-st incorporates state of the art single photon counting technology in the form of the TCC900 and PCS900 computer plug-in card. The PCS900 card is a fast pulse count scalar card that can operate with count rates of up to 100MHz. The TCC900 card is our PC plug-in card for Time Correlated Single Photon Counting Data Acquisition. TCSPC is widely accepted to be the method of choice for maximum sensitivity, dynamic range, accuracy and precision.
