Precision Wavelength Calibration for UV-visible FTS

Abstract

At the 1995 FTS topical meeting, our group presented a description of issues surrounding calibration of the wavenumber scale of our Chelsea Instruments UV/visible FTS.1 Inconsistencies observed when using wavelength standards from Ar II2 and 198Hg3 formed a large part of that discussion. We have continued to work on this problem, with the intent of resolving these discrepancies and probing the limits of precision of the wavenumber scale in FTS.
