Picowatt Photoreceiver from 320 nm to 1060 nm and 900 nm to 1700 nm
The new picowatt photoreceiver series PWPR-2K with switchable gain (109 V/A, 1010 V/A) and a bandwidth from DC to 2 kHz 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 100 fW up to 10 nW.
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.
