Mission Impossible? Measuring Signals Below the Noise Floor with a Lock-In Amplifier
3 October 2017
This article is brought to you by:
Measuring optical signals in the femtowatt (10-15) to nanowatt (10-9) range can be a daunting task. In order to achieve significant improvements in noise rejection we need to turn to a lock-in amplifier, which can improve noise rejection by 3 orders of magnitude or more.

Monitoring Water Quality with Fluorescence Spectroscopy
4 September 2017
This article is brought to you by:
Fluorescence spectroscopy has been used to characterise natural organic matter (NOM) in water. Excitation-Emission maps reveal the nature and concentration of NOM in river water and can be used as a routine analysis technique in water treatment facilities.

Tunable, narrow bandwidth mid-IR laser sources for compact trace gas analysis systems with ppb sensitivity
10 June 2016
This article is brought to you by:
The ultimate instrumentation for trace gas analysis and detection in air quality monitoring as well as industrial process control would be one that can simultaneously provide a sensitive, selective, and fast, multi-gas measurement with wide dynamic range all in a compact and robust system. One of the few such promising technologies that can deliver these requirements is laser based photoacoustic spectroscopy (PAS).
