PWPR-2K Picowatt Photoreceiver With Switchable Gain

PWPR-2K Picowatt Photoreceiver with Switchable Gain

Introducing: FEMTO’s picowatt photoreceiver series PWPR-2K with switchable gain (109 V/A, 1010 V/A) and a bandwidth from DC to 2 kHz.

It is the perfect choice for cw-measurements, time resolved signal acquisitions and highly sensitive modulated measurements.

Other features of the PWPR-2K photoreceiver include: ultra-low noise and NEP ≤ 10 fW/√Hz.  Si and InGaAs models cover the wavelength range from 320 to 1700 nm.

In addition to precise and fast cw-measurements, the relatively large bandwidth from DC to 2 kHz also allows time-resolved and modulated measurements. Particularly, the combination with lock-in amplifiers results in ultra-sensitive measurement systems being almost immune to disturbances from external sources. Used this way, the PWPR-2K can easily detect optical powers from about 100 fW up to 10 nW.
