Amplifiers - Current and Voltage
Low noise, high speed, wideband, lock-in
Photoreceivers, photodetector modules
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. They also offer OEM versions of every
standard amplifier 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.
Use the FEMTO Selection Guides to help you
choose the best amplifier / photoreceiver for
your application.
