FluoroHub-NL: A plug-in NanoLED card with full software control
| 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.

FluoroHub-SD: Six channel stepper motor drive card
 |
This is supplied as standard with our FluoroCube series systems to provide computer control of monochromators, polarisers and sample position. |
FluoroHub-TE: Time expander option
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.
SpectraLED: Plug-in LEDs for phosphorescence steady-state excitation
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.
