Amplifiers - Current and Voltage
|
| 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.
Electro Optical Components ships all FEMTO orders |
|
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, balanced and custom photoreceivers (with or without photodetector modules)
- Lock-in amplifiers
- Remote Power Supply
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.
