Femto-watt photoreceiver (FWPR series)

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.
