Abstract: Optical cells are described for use in spectroscopy applications. The cells include a series of discrete planar reflectors aligned with one another and spaced apart from one another at each end of the sample cavity. The discrete planar reflectors can be surrounded by transparent windows and divergent energy can be removed from the cell cavity via the windows. The cells can define a unique beam path for the energy beam, and there can be no overlapping optical paths through the cell. The cells can provide well-defined detection signals with very high signal-to-noise ratio.

Abstract: Disclosed are spectroscopy systems and methods. A spectroscopy system can include a reference cell and a multi-pass sample cell. The reference arm can include an etalon and a reference cavity containing a reference gas. A system can include a fractional sublimation cold trap. Detectors of the reference and sample arms can detect both intensity and absorption spectra of impinging beams. A frequency calibration based on a reference absorption spectra can be used to analyze a sample absorption spectrum. The analysis can provide information regarding an absorption band shift of the sample absorption spectrum, said shift being related to the isotope concentration of the sample.

Correction functions provided by the internal calibration process can be applied continuously and across an entire sample spectrum. The intensity response of each spectrometer in a spectrophotometer can also be monitored and continuously corrected for stray light, dark current, readout noise, etc.
