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.
