Amplifiers – Current and Voltage – Low noise, high speed, wideband, lock-in
Photoreceivers, Photodetector Module

FEMTO photoreceivers and amplifiers – with or without photodetector modules – are “sophisticated tools for signal recovery” in scientific and industrial applications. They are developed and continually upgraded to be the best products available. FEMTO is a leading manufacturer of high quality low-noise amplifiers.

Products include:

FEMTO offers customized solutions in any quantity.

OEM versions of every standard amplifier can be tailored to meet customer-specific requirements. A common application is the Custom Photoreceiver where a specific photodiode is integrated in the FEMTO amplifier. The noise and capacitive effects of the cable connecting the photodiode are eliminated. This significantly improves the overall performance of the photodiode / amplifier. Please contact us with your needs.
