TCSPC Lifetime Fluorometer

High performance and flexible fluorescence lifetime spectrometer for fast and efficient acquisition of TCSPC lifetime data

The DeltaFlex offers the ultimate in flexibility.

This system is designed for the measurement of luminescence lifetimes ranging over 11 orders of magnitude, without the need to change cables or cards. The heart of the system is the DeltaHub timing electronics, which offers nearly lossless counting and allows for the measurement of lifetimes from 25ps to 1 second.

Our new F-Link bus brings simplicity to modularity. Simply add any component to the instrument and the system automatically detects the new addition making it accessible from the software.

Finally, with biological probes and applications such as photovoltaics moving further into the NIR, capability for time-resolved measurements in this range is very important.  The DeltaFlex can couple with a range of NIR detectors to offer a solution.

The DeltaFlex system uses our interchangeable range of DeltaDiode excitation sources, DeltaHub timing electronics and PPD picosecond detection modules.  Add excitation and/or emission monochromators for wavelength selection and complete spectral collection such as TRES.

The DeltaFlex can be easily upgraded to incorporate motorized devices through the F-Link spectrometer bus.

    • Steady-State


Compact, affordable and modular fluorescence lifetime spectrometer – time correlated single photon counting for any lab

The DeltaPro has taken the complexity of time correlated single photon counting (TCSPC) and made it simple and affordable. Any lab can exploit the power of fluorescence dynamics using TCSPC. This system enables the seamless measurement of luminescence lifetimes from picoseconds to 1 second, using our DeltaHub timing electronics.

The DeltaPro takes advantage of interchangeable pulsed laser-diode and LED light-sources. The NanoLED and DeltaDiode range of sources cover discrete emission wavelengths from 250 nm to the near-IR and enables measurement of lifetimes from ps to µs. By simply adding a SpectraLED source to the system, lifetimes of µs to 1 second can be measured. Lifetimes ranging over 11 orders of magnitude measured with one compact and affordable system.

The DeltaPro system is modular. It can easily be upgraded to incorporate motorized devices, such as automated focusing and motorized polarizers through the F-Link spectrometer bus.
