DeltaPro
TCSPC Lifetime Fluorometer
The DeltaPro is a compact, modular, and affordable time-correlated single-photon counting (TCSPC) fluorescence lifetime spectrometer for any lab. It enables seamless measurement of luminescence lifetimes ranging from 25 ps up to 1 second—covering 11 orders of magnitude—in a single system with fast acquisition and simple USB connectivity. Easily upgradable via F‑Link for accessories like motorized polarizers and focuses, it supports filter-based wavelength selection and various light sources from UV to NIR.

Applications of DeltaPro
PL-upconversion
Frequency upconversion from NIR to visible using lanthanide based nanomaterials. Lanthanide based nanomaterials exhibits a unique fluorescence anti-Stokes shift enabling conversion of NIR into visible shorter wavelengths.
Local viscosity determination
Certain fluorescent molecules known as molecular rotors, can be employed to estimate the nanoscale viscosity in micro heterogeneous systems by measurement of their fluorescence lifetime.
