Abstract: Aspects of spectrometer reference calibration are described. In one embodiment, a diagnostic measurement for evaluation of an aspect of calibration in spectroscopy is performed. A result of the diagnostic measurement is analyzed to determine a deviation from an expected result. Based on the analysis, a correction algorithm may be applied to the aspect of calibration, in view of the deviation. In some embodiments, a product model diagnostic measurement is also performed for further evaluation of the aspect of calibration. A result of the product model diagnostic measurement is analyzed to determine a product model deviation from an expected result of the product model diagnostic measurement, and a product model correction algorithm is applied, if necessary. According to aspects of the embodiments described herein, using reference standards permits reconstruction of calibration parameters without any need for a master instrument or other forms of calibrated reference instrumentation.

Abstract: Aspects of a tandem dispersive range monochromator and data knitting for the monochromator are described herein. In one embodiment, the monochromator includes a tandem diffraction grating, a grating drive motor that rotates the tandem diffraction grating to provide, by diffraction of broadband light, first dispersed wavelengths of light and second dispersed wavelengths of light, a detector that detects a first reflection from the first dispersed wavelengths of light and a second reflection from the second dispersed wavelengths of light, and processing circuitry that knits together data values from the first reflection and data values from the second reflection to provide a spectrum of combined data values. By using a tandem diffraction grating having different dispersive surfaces, measurements of relatively high precision and quality may be taken throughout a wider spectral range, and the measurements may be knitted together to provide a spectrum of combined data values.
