The OB920
allows automatic acquisition and analysis of time resolved
spectra, fluorescence anisotropy (with polariser option)
and temperature dependence (with cryostat option).
The OB920 consists of the following hardware :
-
Nanosecond pulsed flashlamp,
including driver and start synchronisation
photomultiplier, gas filling and vacuum pumping station
-
Excitation monochromator: 100 mm
focal length low temporal dispersion, high stray light
rejection. Computer controlled wavelength selection,
manual slit selection, wavelength accuracy 1nm
-
Sample chamber with liquid cooled
cuvette holder and temperature monitor,
-
Emission monochromator: 100 mm focal
length low temporal dispersion, high stray light
rejection. Computer controlled wavelength selection,
manual slit selection, wavelength accuracy 1nm
-
Single photon counting stop
photomultiplier
-
TCC900 card for TCSPC data
acquisition
-
Dedicated PC running F900 software
for comprehensive spectrometer control, performance
monitoring, fluorescence lifetime data acquisition and
analysis library
Software Interface :
The F900
advanced software is a user friendly package providing the
user with complete instrument control. The F900 software
controls measurement set-up and data acquisition all
through a transparent menu. Control of the hardware
settings on the TCC900 card are easily accessed through
the F900 software. The software also provides the user
with decay curve analysis for up to four exponential decay
processes.

System Flexibility :
The modular design of every
spectrometer provides maximum flexibility to meet the
requirements for a wide range of applications. We can
offer a range of accessories for use with the instrument
but we also have off the shelf up-grade routes that are
quick and easy to implement.
