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:
- Current amplifiers – fixed & variable gain transimpedance amplifiers – TIA
- Voltage amplifiers – low frequency, wideband and logarithmic voltage amplifiers
- High Speed GHz amplifiers
- Custom amplifiers
- Photoreceivers – ultra-fast fixed & variable gain, custom photoreceivers (with or without photodetector modules)
- Balanced Photoreceivers
- Lock-in amplifiers
- Remote Power Supply
- Amplifier Interface Software
- Amplifier Accessories
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.
