FEMTO Messtechnik GmbH is a leading manufacturer of low-noise amplifier modules.
■FWPR-20 - A photoreceiver combined with a low-noise Si/InGaAs photodiode and a very high-gain (maximum: 10^12 V/A) low-noise transimpedance amplifier. - Achieves a very low NEP value (minimum: 0.7 fW/√Hz) and high sensitivity in the femtowatt range. - For detection with the photoreceiver alone, it can detect optical power down to approximately 50 fW, and when combined with a Femto lock-in amplifier, it achieves high sensitivity in the sub-femtowatt range. - Due to its very high sensitivity, it can be used in many applications. - It can be used as an alternative to APD, PMT, and cooled Ge photodiodes without the need for expensive high-voltage power supplies or cooling devices.

basic information
■Si Model FWPR-20-SI - Wavelength range: 320 to 1100 nm - Particularly effective for applications where timing is not critically important, such as photon counters with signal durations of several tens of milliseconds or more. - Achieves high quantum efficiency and S/N ratio comparable to APD-based single photon counting modules. ■InGaAs Model FWPR-20-IN - Wavelength range: 900 to 1700 nm - Convenient for replacing expensive and difficult-to-handle external amplifier-based liquid nitrogen-cooled Ge detector systems. - Equipped with a low-noise, high-gain amplifier signal, allowing the photoreceiver to obtain signals in the volt (V) range on its own.
