Photoreceivers

Femtowatt (ultra low noise min. NEP 0.7fW/√Hz), variable gain (10E3 to 10E11 V/W) and fixed gain photoreceivers offer a solution to measuring fast and precise small optical signals. By combining a low noise transimpedance amplifier with a silicon or InGaAs photodiode a broad wavelength range from 190nm up to 1700nm is covered. Ideal for all lab scenarios, fibre alignment, fast power monitoring, testing laser diodes, linearity measurements over 10 decades, and industrial control and aligment are just a few applications.

Femtowatt Photoreceiver Series FWPR-20

Ultra-low-noise photoreceivers for direct detection of optical powers as low as 50 femto Watts.

The FWPR-20 series Photoreceivers combine low-noise Si or InGaAs photodiodes with a specially designed transimpedance amplifier with extremely high gain of up to 1012 V/A and very low noise. This unique combination results in a photoreceiver with Femtowatt sensitivity due to its exceptional low NEP of minimum 0.7 fW/√Hz. Direct detection of optical powers down to ca. 50 fW is possible and when combined with an optional FEMTO Lock-In Amplifier even sub-Femtowatt sensitivity can be achieved.

Applications include fluorescence measurements, spectroscopy, electrophoresis, chromatography, alternatives to photomultiplier tubes (PMTs), Avalanche Photodiodes (APDs) and Liquid Nitrogen Cooled Germanium Photodiodes.
