Abstract: A fluid analyzer includes an optical source and an optical detector defining an optical beam path through an interrogation region of a fluid flow cell. Motion control devices determine position of the interrogation region. Flow-control devices conduct analyte and reference fluids and manipulate fluid flow in response to control signals to position a fluid boundary across the interrogation region. A controller (1) generates a time-varying motion modulation signal to move the interrogation region across the fluid boundary, (2) samples an output signal from the optical detector at one time in which the interrogation region contains more analyte fluid than reference fluid and at a time at which the interrogation region contains more reference fluid than analyte fluid, thereby generating corresponding output signal samples, and (3) determines from the output signal samples a measurement value indicative of an optically measured characteristic of the analyte fluid.

Abstract: A fluid analyzer includes an optical source and detector defining a beam path of an optical beam, and a fluid flow cell on the beam path defining an interrogation region in a fluid channel in which the optical beam interacts with fluids. One or more flow-control devices conduct a particle in a fluid through the fluid channel. A motion system moves the interrogation region relative to the fluid channel in response to a motion signal, and a controller (1) generates the motion signal having a time-varying characteristic, (2) samples an output signal from the optical detector at respective intervals of the motion signal during which the interrogation region contains and does not contain the particle, and (3) determines from output signal samples a measurement value indicative of an optically measured characteristic of the particle.

Abstract: A fluid analyzer includes an optical source and an optical detector defining an optical beam path through an interrogation region of a fluid flow cell. Flow-control devices conduct analyte and reference fluids through a channel and the interrogation region, and manipulate fluid flow in response to control signals to move a fluid boundary separating the analyte and reference fluids across the interrogation region. A controller generates control signals to (1) cause the fluid boundary to be moved across the interrogation region accordingly, (2) sample an output signal from the optical detector at a first interval during which the interrogation region contains more analyte fluid than reference fluid and at a second interval during which the interrogation region contains more reference fluid than analyte fluid, and (3) determine from samples of the output signal a measurement value indicative of an optically measured characteristic of the analyte fluid.

Abstract: A tunable laser has a solid state laser medium having an optical gain region and generates coherent radiation through a facet. A lens collects the coherent radiation and generates a collimated light beam. Components of an external cavity include a reflective surface and an optical filter, the reflective surface reflecting the collimated beam back to the lens and the laser medium, the optical filter positioned between the reflective surface and the lens and having two surfaces with a thermally tunable optical transmission band within the optical gain region of the laser medium. The optical filter (1) transmits a predominant portion of the collimated beam at a desired wavelength of operation, and (2) specularly reflects a remaining portion of the collimated beam from each surface, the collimated beam being incident on the optical filter such that the reflected collimated beams propagate at a non-zero angle with respect to the incident collimated beam.
