PWPR-2K-SI Photodetector

Introduction:
Piva Photoreceiver PWPR-2K Series
The PWPR-2K photoreceiver is factory-equipped with an optical free-space input. Options are available between a 1.035″-40 threaded flange (FST) and a 25 mm unthreaded flange (FS). Both types offer broad compatibility with optical standard accessories such as tubes, lenses, holder systems, and optical adapters from various manufacturers. For example, the threaded free-space input (FST) can be easily converted to a fiber optic input by screwing on optionally available fiber adapters (PRA-FC and PRA-FSMA), ensuring very high and stable coupling efficiency.

Product Features:
Ultra-low noise, NEP less than fW/√Hz
Si and InGaAs models cover a wavelength range from 320 to 1700 nm.
Bandwidth DC to 2 kHz
Switchable transimpedance gain 10⁹ V/A, 10¹⁰ V/A
Free-space input 1.035″-40 thread, optional 25 mm diameter unthreaded
Optionally available screw adapters for easy conversion to fiber optic input (FC and FSMA)

Applications:
Spectroscopy, reflection and transmission measurements
Time-resolved optical pulse and power measurements
Light source characterization
High-sensitivity applications using chopper modulation
Optical front-end for oscilloscopes, A/D converters, and lock-in amplifiers
