Abstract
An absorption spectrometer with self-referencing calibration takes two measurements along a first and second path having different distances through a sample while largely preserving all other aspects of the optical path and system constant. Comparing these two measurements allows extraction of the spectrum largely free from instrument-specific artifacts.
