Measurement of Fluorescence Lifetimes

Hamamatsu Photonics has released Quantaurus Tau, a compact easy-to use system for measuring the fluorescence lifetime of photoluminescent materials in thin film, powder, solid, or liquid form from sub-nanoseconds to the millisecond range, with single-photon-counting sensitivity.

Liquid samples can be cooled down to -196°C. Seven LEDs allow sample excitation from 280 nm to 630 nm. The dedicated software includes a variety of measurement and analysis functions and allows fitting of up to five exponentials. Furthermore, Quantaurus-Tau features optional add-ons for performing phosphorescence measurements
