    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 (12) includes an image sensor (28), an illumination source (14), a refractive, optical element (24A), a mover assembly (24C) (29), and a control system (30). The image sensor (28) acquires data to construct a two-dimensional spectral image (13A) during a data acquisition time (346). The illumination source (14) generates an illumination beam (16) that illuminates the sample (10) to create a modified beam (16I) that follows a beam path (16B) from the sample (10) to the image sensor (28). During the data acquisition time (346), the control system (30) controls the illumination source (14) to generate the illumination beam (16), and controls the image sensor (28) to capture the data. Further, during the data acquisition time (346), an effective optical path segment (45) of the beam path (16B) is modulated.

    Abstract: Spectrally analyzing an unknown sample (10A) includes (i) providing a spatially homogeneous region (10B) of the unknown sample (10A); (ii) directing a plurality of interrogation beams (16) at the spatially homogeneous region (10B) with a laser source (14), (iii) acquiring a separate output image (245) while the unknown sample (10A) is illuminated by each of the interrogation beams (16) with an image sensor (26A); and (iv) analyzing less than fifty output images (245) to analyze whether a characteristic is present in the unknown sample (10A) with a control system (28) that includes a processor. Each of the interrogation beams (16) is nominally monochromatic and has a different interrogation wavelength that is in the mid-infrared spectral range.

    Abstract: An imaging and capture micro-dissection microscope (12) for spectrally analyzing a sample (10) and isolating a region of interest (210) in the sample (10) includes (i) a stage (26A) that retains the sample (10); (ii) an analysis laser assembly (14) that generates a coherent interrogation beam (16A) that is directed at the sample (10), the interrogation beam (16A) having a center wavelength that is in the infrared region; (iii) an image sensor (24A) that receives light from the sample (10), the image sensor (24A) capturing image information that is used to identify the region of interest (210) in the sample (10); (iv) a separation assembly (18) that separates the region of interest (210) from the sample (10) while the sample (10) is retained by the stage (26A); and (v) a capturing assembly (20) that captures the region of interest (210).
