Multi Frequency Phase Fluorometers
The Multi Frequency Phase Fluorometer (MFPF) is an instrument platform for measurement of luminescence lifetime, phase and intensity. The MFPF product line’s flexibility enables you to assemble a versatile fluorescence development platform at an economical price point. Rugged electronics, simplified algorithms, modular plug-and-play design, and easy to use interface make the MFPF a cost effective tool for laboratory use. The MFPF fluorescence development platform allows researchers and scientists to focus on data solutions in biology, medicine, environmental science, and chemistry applications without the need of an extensive background in electronics, high speed data acquisition, digital signal processing, and/or optical engineering.

The MFPF family of products provides for:
- Fluorescence lifetime measurements that are unaffected by fiber bending, stray light and intensity
- Wide dynamic measurement range of lifetime and optical intensity
- Flexible configuration using SMA terminated fibers (glass and plastic)
- Digital lock-in type measurement giving minimal phase noise
- Electronics designed to insure low phase drift
Available in single channel or dual channel.
