Abstract
Optical gas refractometry has enabled new pressure standards to be developed based on a dual Fixed Length Optical Cavity (FLOC) system. NIST in partnership with MKS Instruments has created a portable FLOC pressure standard based gas refractivity. A key challenge for accurate measurements is the characterization of cavity distortions when pressurized. A method for determination of the distortion constants will be presented based on using two gasses of known refractive index. Using this two-gas technique, the distortions on the portable FLOC pressure standard are measured to 1 part in 106 (k=1).Proceedings Title
