Abstract: An optical component group for use in a spectrometer module of a system for measuring whole-blood hemoglobin parameters or whole-blood bilirubin parameters. The optical component group includes a light dispersing element and an achromatic lens assembly disposed between the light dispersing element and a light entrance port of the spectrometer module where the achromatic lens assembly is thermo-compensating permitting thermal expansion and contraction of the achromatic lens assembly in a linear direction where the linear directions is also transverse to a light beam from the light entrance port through the achromatic lens assembly and to the light dispersing element and back through the achromatic lens assembly.

Abstract: Aspects of a micromirror spectrophotometer assembly are described. In one example case, an instrument includes a diffraction grating to disperse broadband light over a range of wavelengths, a detector, a digital micromirror device (DMD) configured to scan through and reflect at least a portion of the range of wavelengths toward the detector, and a base platform having a number of integrally formed assembly mounts. The assembly mounts are formed to align and secure the diffraction grating, the detector, the DMD, and other optical components of the instrument in a predetermined arrangement. The instrument can also include a reference paddle having a reference material for calibration of the instrument, and a rotatable sample tray to rotate a sample placed on the sample tray for measurement.

Abstract: Methods and systems for spectrometer dark correction are described which achieve more stable baselines, especially towards the edges where intensity correction magnifies any non-zero results of dark subtraction, and changes in dark current due to changes in temperature of the camera window frame are typically more pronounced. The resulting induced curvature of the baseline makes quantitation difficult in these regions. Use of the present disclosure may provide metrics for the identification of system failure states such as loss of camera vacuum seal, drift in the temperature stabilization, and light leaks. In system aspects of the present disclosure, a processor receives signals from a light detector in the spectrometer and executes software programs to calculate spectral responses, sum or average results, and perform other operations necessary to carry out the disclosed methods. In most preferred embodiments, the light signals received from a sample are used for Raman analysis.
