FluoroHub
It's true that single photon counting (SPC) systems offer the best overall performance in terms of signal-to-noise, dynamic range, statistical methodology and time resolution. One reason why SPC is not more widely used is because the associated electronics are perceived as being complex and user-unfriendly. There has been a push in recent years towards more user-friendly electronics, but unfortunately these developments have often been at the expense of data quality and system modularity.
Our new FluoroHub offers the best of both worlds - a fully integrated PC-based solution that doesn't compromise your data quality. Having pioneered high quality "out-of-the-box" light sources and detectors for SPC, we applied the same design philosophy to the DataStation FluoroHub, and the result is the most complete and easy to use SPC solution yet!
The FluoroHub is a semi-modular product that brings together the best technology from a number of major manufacturers to achieve the most dependable performance available, with full control under Windows software. The FluoroHub supports all three most commonly used SPC measurement modes:
All FluoroHub settings, such as time range, delay, and peak preset are selected using a tree navigation control pane. Additional hardware (e.g. NanoLED, monochromators, polarisers etc) is controlled using different tabs on the same pane.
The measurement data is managed using intuitive tree navigation in the pane above.
What could be simpler?
We chose the word "FluoroHub" to emphasise that this new product offers more than simply timing electronics. As the diagram opposite shows, the FluoroHub forms the electronic core of our latest generation fluorescence lifetime systems.In addition to four expansion buses, the FluoroHub even includes coaxial delay lines, connections for detector power and laser interlock.Plug-in options include a NanoLED pulsed laser diode control board, and a six channel stepper motor drive board for monochromator and polariser control. These options are fully software controlled and are auto-detected by the DataStation software.
The HORIBA Jobin Yvon IBH FluoroHub... an easy decision
There are currently four plug-in options for the FluoroHub:
More accessories are under development, so watch this space!
The NanoLED is a novel pulsed light source system that uses a variety of light emitting diode (LED) and laser diode (LD) devices to generate picosecond and nanosecond optical pulses over a wide spectral range. LED-based sources generate nanosecond pulses in the UV and visible, while LD-based sources generate picosecond or nanosecond pulses in the violet and red.
The FluroHub-NL NanoLED controller is interfaced to our FMAS software allowing NanoLED settings to be stored with the general instrument configuration. Parameters include repetition rate, synchronisation delay, and synchronisation mode (for selection of internal or external triggering).
When external triggering mode is selected, the repetition rate is controlled by an external signal presented to the synchronisation input. In both synchronisation modes, NIM and TTL-compatible synchronisation outputs are provided for connection to the acquisition electronics. These synchronisation outputs are delayed relative to the optical pulse as determined by the sync delay parameter allowing nanosecond decays to be measured in reversed TAC mode (to maximise the data collection rate). If necessary, the NanoLED operation can be linked to the sample chamber lid microswitches to inhibit emission when the lid is removed.
Note that the FluoroHub can drive LEDs directly to generate microsecond and millisecond excitation pulses suitable for phosphorescence measurements. For more information see FluoroHub-µs below.
This is supplied as standard with our FluoroCube series systems to provide computer control of monochromators, polarisers and sample position.
The range of time-resolution (i.e. time-per-point) settings available using the FluoroHub is sufficient for the vast majority of applications. For applications requiring <7ps/point resolution, specify the FluoroHub-TE time expander option.
The FluoroHub-TE extends the resolution of the FluoroHub's TCSPC electronics to 0.7ps/point.
The standard FluoroHub package includes pulse counting electronics to enable phosphorescence measurements in multi-channel scaling (MCS) mode. Lifetimes from a few microseconds to several minutes can be made in MCS mode in conjunction with a low repetition rate excitation source such as xenon flashlamps, or a nitrogen laser.
As a low cost alternative to the xenon flashlamp and Nitrogen laser, we now offer a range of pulsed LEDs that connect directly to the FluoroHub module's expansion port A. These inexpensive SpectraLED sources are ideal for lifetimes measurements from 100µs and are available at wavelengths from 370nm. The optical pulse duration can be programmed from within DataStation to obtain the optimum pulse duration for each sample. No additional electronics are required.
