Femtowatt Photoreceiver

Application Suggestions
Fluorescence Measurements
NIR Spectroscopy
Electrophoresis
Chromatography
Replacement of Photomultiplier Tubes (PMTs), Avalanche Photodiodes (APDs) and Cooled Ge Photodiodes
The PDF series of Femtowatt Photoreceivers combine selected ultra low noise Si or InGaAs photodiodes with a specially designed transimpedance amplifier offering extremely high gain of up to 1012 V/A. This results in a unique photoreceiver with Femtowatt sensitivity due to an exceptional low minimum NEP of 1.4 fW/Hz1/2. This allows direct detection of optical powers of about 10 fW. When combined with a lock-in amplifier, it is possible to detect optical power down to sub fW levels.
