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: An assembly (10) for generating a laser beam (12) includes a beam steering assembly (18); a laser assembly (16) that is tunable over a tunable range; and a controller (20). The laser assembly (16) generates a laser beam (12) that is directed at the beam steering assembly (18). The controller (20) dynamically controls the beam steering assembly (18) to dynamically steer the laser beam (12) as the laser assembly (16) is tuned over at least a portion of the tunable range. As a result thereof, the laser beam (12) is actively steered along a desired beam path (12A) while the wavelength of the laser beam (12) is varied.
