DC TO 2 KHZ PICOWATT PHOTORECEIVER
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.
