    Abstract: A flow cell assembly (16) for a fluid analyzer (14) that analyzes a sample (12) includes (i) a base (350) that includes a base window (350B); (ii) a cap (352) having a cap window (352B) that is spaced apart from the base window (350B); and (iii) a gasket (360) that is secured to and positioned between the base (350) and the cap (352), the gasket (360) having a gasket body (360A) that includes a gasket opening (360B). The gasket body (360A), the base (350) and the cap (352) cooperate to define a flow cell chamber (362). Moreover, an inlet passageway (366) extends into the flow cell chamber (362) to direct the sample (12) into the flow cell chamber (362); and an outlet passageway (368) extends into the flow cell chamber (362) to allow the sample (12) to exit the flow cell chamber (362).

    Abstract: A spectral imaging device (12) includes an image sensor (28), a tunable light source (14), an optical assembly (17), and a control system (30). The optical assembly (17) includes a first refractive element (24A) and a second refractive element (24B) that are spaced apart from one another by a first separation distance. The refractive elements (24A) (24B) have an element optical thickness and a Fourier space component of the optical frequency dependent transmittance function. Further, the element optical thickness of each refractive element (24A) (24B) and the first separation distance are set such that the Fourier space components of the optical frequency dependent transmittance function of each refractive element (24A) (24B) fall outside a Fourier space measurement passband.

    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).

    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 follow a beam path (16B) from the sample (10) to the image sensor (28). The refractive, optical element (24A) is spaced apart a separation distance (42) from the sample (10) along the beam path (16B). During the data acquisition time (346), the control system (30) controls the illumination source (14) to generate the illumination beam (16), controls the mover assembly (29) (24C) to modulate the separation distance (42), and controls the image sensor (28) to capture the data.

    Abstract: A laser source (340) that generates an output beam (354) that is directed along a beam axis (354A) that is coaxial with a first axis and orthogonal to a second axis comprises a first frame (356), a laser (358), and a first mounting assembly (360). The laser (358) generates the output beam (354) that is directed along the beam axis (354A). The first mounting assembly (360) couples the laser (358) to the first frame (356). The first mounting assembly (360) allows the laser (358) to expand and contract relative to the first frame (356) along the first axis and along the second axis, while maintaining alignment of the output beam (354) so the beam axis (354A) is substantially coaxial with the first axis. The first mounting assembly (360) can include a first fastener assembly (366) that couples the laser (358) to the first frame (356), and a first alignment assembly (368) that maintains alignment of the laser (358) along a first alignment axis (370) that is substantially parallel to the first axis.
