Universidad de Zaragoza (orcid)0000-0002-4746-3139 Dual-Wavelength Measurement System for Absorbance Chemical Sensing 2007 A novel compact dual-wavelength measurement system for absorbance chemical sensing incorporating digital lock-in amplifiers is reported. Its main innovation is the introduction of a reference wavelength to correct the possible non-specific optical changes of the system. The performance of the instrumentation has been tested on a laboratory setup and with integrated optical absorbance sensors.
