The FS920 is a modular, computer controlled L - geometry spectrometer for acquiring steady state luminescence spectra in the ultraviolet - visible - near infra red spectral range with single photon counting sensitivity. It combines ultimate sensitivity with high spectral resolution and excellent stray light rejection.

The configuration of the FS920 consists of the following hardware :

• CW 450 W xenon arc lamp

• Excitation monochromator: 300mm focal length, Czerny-Turner design triple grating turret facility with computer controlled wavelength selection and computer controlled continuously adjustable slits. Stray light rejection 1:105 , resolution down to 0.05nm

• versatile sample chamber with integral controller, safety shutters, signal attenuator and filter holders

• Emission monochromator: 300mm focal length, Czerny-Turner design triple grating turret facility with computer controlled wavelength selection and computer controlled continuously adjustable slits. Stray light rejection 1:105 , resolution down to 0.05nm

• single photon counting stop photomultiplier

• PCS900 card for single photon counting data acquisition

• Dedicated PC running F900 software for comprehensive spectrometer control, performance monitoring, fluorescence spectral data acquisition, correction and analysis library.
   

Software Interface  :

In keeping with the modularity of the FS920 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 the PCS900 data acquisition cards are easily accessed through the F900 software.
