Low noise amplifiers, 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. FEMTO Ultra Low Noise Current Amplifier Current Amplifier with 400 MHz Bandwidth 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.
