The FS920P is a modular, computer
controlled L - geometry spectrometer for acquiring steady
state luminescence spectra, time resolved phosphorescence
spectra and the associated decays 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 FS920P
consists of the following hardware :
-
CW 450 Wxenon arc lamp
-
Pulsed Xenon flashlamp under computer
control to measure phosphorescence decays. Pulses 2 to 7
µs with an average power >60 W up to 100 Hz.
-
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 FS920P 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.

Data Acquisition :
The FS920P
incorporates state of the art single photon counting
technology in the form of the PCS900 computer plug-in
card. The PCS900 card is a fast pulse count scalar card
that can operate in two modes one for steady state
acquisition, the other for multi-channel scaling lifetime
acquisition. In steady state mode the card can operate
with count rates of up to 100MHz. For MCS acquisition the
minimum time window is 200ns/channel.
