What is Fluorescence? The term fluorescence refers to one type of luminescence. Luminescence, broadly defined, is light emission from a molecule. There are several types of luminescence.
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.
