RFA Systems designs, develops, and manufactures innovative spectroscopy-based optical instruments for: combustion research, remote chemical sensing, industrial process measurement and control, pharmaceutical production control, real-time multi-species molecular gas detection for homeland security and fire-safety applications, and university and government laboratory general R&D. We offer the only commercially available Real-time Fuel Air (RFA) ratio analyzer with millisecond time resolution. Our main product line, the RFA-2000 uses the principle of infrared absorption in conjunction with a small-volume extractively sampled optical cell to provide accurate and high-speed measurements of the fluctuations in fuel-to-air ratios of most hydrocarbons. The RFA-2000 is an alignment-free, rugged and easy to use instrument that has demonstrated itself to be field-deployable and cost-effective. Our new product, the Model R3 Raman engine is a compact and rugged imaging Raman spectrograph with an aperture of f/1.7 which permits a cost-effective and easy-to-use instrument for the measurement of gaseous, liquid, or solid  chemical species using fiber optic probes.

Since its inception, RFA Systems has focused its efforts on the development and manufacture of rugged, "tweak-free", easy-to-use optical instruments for spectroscopic based chemical sensing systems. Our product design philosophy is simple: to provide spectroscopy instruments for research and industrial process control that is rugged, reliable, and most importantly, easy to use. Our company has been delivering high quality products and services with excellent customer satisfaction ever since it was founded in 1998.
