Latest innovation from FEMTO Messtechnik GmbH - Picowatt Photoreceiver from 320nm to 1060nm and 900nm to 1700nm

21 Nov 2017

The new picowatt photoreceiver series PWPR-2K with switchable gain (109 V/A, 1010

V/A) and a bandwidth from DC to 2kHz is the perfect choice for cw-measurements,

time resolved signal acquisitions and highly sensitive modulated measurements, in

addition to precise and fast cw-measurements.

Particularly the combination with lock-in amplifiers results in ultra-sensitive

measurement systems being almost immune to disturbances from external sources. In

this way the PWPR-2K can easily detect optical powers from about 100fW up to 10nW.

Offering both free space and fibre coupled formats, both Si and InGaAs PIN diode

options are available. Carefully designed EMC housings include fixing holes for both

laboratory and OEM constructions.

The output voltage range is up to +10V, with an offset adjustment by a potentiometer.

The photoreceiver includes output short-circuit protection. As is standard for all

FEMTO products, a power supply with ±15V via 3-pin Lemo® socket, PS-15, is

supplied separately.
