FEATURES
Ultra-low noise, NEP ≤ 10 fW/√Hz
Si and InGaAs models cover the wavelength range from 320 to 1700 nm
Bandwidth DC to 2 kHz
Transimpedance gain switchable 109 V/A, 1010 V/A
Free-space input 1.035′-40 threaded, alternatively 25 mm diameter unthreaded
Easily convertible to fiber optic input (FC and FSMA) with optionally available screw-on adapters
MEASURING SMALLEST OPTICAL SIGNALS FROM DC TO 2 KHZ
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. In this way the PWPR-2K can easily detect optical powers from about 100 fW up to 10 nW.
COMPATIBILITY WITH OPTICAL BENCH (FREE SPACE) AND FIBER OPTICS
The PWPR-2K photoreceivers are factory equipped with an optical free-space input. There is the choice between a 1.035′-40 threaded flange (FST) and a 25 mm unthreaded flange (FS). Both types offer a broad compatibility with optical standard accessories like tubes, lenses, cage systems and optical adapters from various manufacturers. The threaded free-space input (FST) e.g. can be easily converted to an optical fiber input by screwing the optionally available fiber adapters (PRA-FC and PRA-FSMA) on it.
The relatively large area detectors make optical alignment easy in free-space applications and ensure a very high and stable coupling efficiency when using the optionally available fiber optic adapters PRA-FC and PRA-FSMA.
All PWPR-2K photoreceivers feature both UNC 8-32 and M4 tapped holes for mounting on metric and imperial threaded standard posts.
