Nikira Labs - Model OEA - Optical Extinction Analyzers - Brochure

Nikira Labs’ Open-Path Optical Extinction Analyzers (OEAs) are the next generation instruments for visibility and aerosol studies. They measure the optical extinction and visibility in air with unprecedented accuracy. By combining open-path cavity ringdown measurements with a patented self-referencing scheme, the analyzer is able to measure the optical extinction due to ambient aerosols with high precision, minimal sample handling, and little to no drift. The OEA-532 was compared to the Optec NGN-2a Nephelometer in Christman Airfield (Fort Collins, CO). The results showed that the OEA-532 provides much faster data and is able to observe more rapid changes in optical extinction.
