Introduction
MFPF System Overview
The MultiFrequency Phase Fluorometer (MFPF) is a flexible platform for measuring luminescence
lifetime, phase and intensity. The MFPF is a compact, self-contained, frequency-domain luminescence
monitor that uses LED excitation and photodiode detection with filter-based wavelength selection for
easy experimental set-up and control. Because the unit is self-contained, it is invariant to fiber bending
and stray light, and has a wide dynamic range of optical intensity as well as low optical and electronic
crosstalk, and low drift and phase noise. Therefore, the MFPF is especially useful for oxygen sensing
applications where sensitivity to drift is important and where sample set-ups must be left undisturbed for
long periods of time.
