FIRST IN PHOTONICS
Signal Recovery designs, manufactures and sells lock-in amplifiers, signal averagers, amplifiers, light choppers, signal multiplexers, and specialized counters.
The model 5105 was a compact dual-phase lock-in amplifier which is no longer manufactured by Signal Recovery. The system has been superceded by the model 7230 digital signal processing (DSP) lock-in amplifier.
Over the past few decades, the Signal Recovery Models 5209 (single-phase) and 5210 (dual-phase) have become the benchmark lock-in amplifiers against which others are judged. They are widely referenced in technical publications describing a diverse range of research applications including optical, electrochemical, electronic, mechanical and fundamental physical studies.
