TCSPC Lifetime Fluorometer

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.

Fluorescence Anisotropy Studies
Fluorescence Anisotropy Studies
Polarized light striking a fluorescent molecule results in polarized fluorescence. This polarized emission gradually returns to unpolarized fluorescence depending on rotational diffusion and other factors. Anisotropy is directly related to the polarization, and is the ratio of the polarized light component to the total light intensity.

The Measurement of Singlet Oxygen Lifetime Sensitized using Rose Bengal
The study of singlet oxygen (1O2) is of interest, principally, as it is a highly reactive species. It can be produced by photosensitisation, usually of a molecule such as a dye or porphyrin. Thus, by the appropriate selection of sensitiser, the presence of oxygen and light, 1O2 can be selectively generated. From a biological aspect it has the ability to damage and destroy cells, which has lead to interest in its use as an anticancer agent in photodynamic therapy (PDT).
