    Abstract: A fluid analyzer (214) that analyzes a sample (12) includes an analyzer frame (236); a test cell assembly (242) that receives the sample (12); a laser assembly (238) that generates a laser beam (239A) a signal detector assembly (232) and a self-check assembly (230). The self-check assembly (230) includes (i) a check frame (230A); (ii) a check substance (230E) with known spectral characteristics; and (iii) a check frame mover (230B) that selectively moves the check frame (230A) between a self-check position (231 B) and a test position (231 A) relative to the analyzer frame (236). In the self-check position (231 B), the laser beam (239A) is directed through the check substance (230E) to evaluate the performance of the fluid analyzer (214). In the test position (231 A), the laser beam (239A) is directed through the sample (12) in the test cell assembly (242) to evaluate the sample (12).

    Abstract: A spectral imaging device (1312) for capturing one or more, two-dimensional, spectral images (1313A) of a sample (1310) including (i) an image sensor (1328), (ii) an illumination source (1314), (iii) a beam path adjuster (1362), and (iv) a control system (1330). The illumination source (1314) that generates an illumination beam (1316) that is directed along an incident sample beam path (1360) at the sample (1310). The beam path adjuster (1362) selectively adjusts the incident sample beam path (1360). The control system (1330) controls (i) the illumination source (1314) to generate the illumination beam during the first capture time, (ii) the image sensor (1328) during the first capture time to capture first information for the first spectral image (1313A), and (iii) the beam path adjuster (1362) to selectively adjust the incident sample beam path (1360) relative to the sample (1310) during the first capture time while the image sensor (1328) is accumulating the information for the first spectral image (1313A).
