Abstract: A microscopic object collecting method collects a plurality of microscopic objects dispersed in a sample. The method includes: irradiating a thin film with a plurality of laser beams, the thin film being provided on a bottom surface of an collection container containing the sample, the plurality of laser beams being separated from each other; and heating the sample with the plurality of laser beams to generate a plurality of microbubbles corresponding to the plurality of laser beams and to generate heat convection in the sample. An interval between adjacent two laser beams of the plurality of laser beams is narrower than a distance that allows three larger microbubbles to be virtually arranged in a gap between two microbubbles corresponding to the two laser beams, each of the three larger microbubbles being the larger one of the two microbubbles.

Abstract: A light-emitting module includes a substrate, a surface light-emitting element, and an optical waveguide. The surface light-emitting element includes light sources and is attached to the substrate. The optical waveguide is attached to the surface light-emitting element in a state in which the optical waveguide covers the light sources. The optical waveguide extends in an axial direction with a refractive index distribution in a radial direction. The optical waveguide condenses light beams emitted from the surface light-emitting element.

Abstract: A biosignal sensor includes a substrate, first light-emitting elements, second light-emitting elements, and light-receiving elements. The light-receiving elements are positioned individually spaced apart by different distances from the first light-emitting elements and the second light-emitting elements and receive light from the first light-emitting elements and the second light-emitting elements. The plurality of light-receiving elements are linearly or substantially linearly aligned in an X direction. The first light-emitting elements and the second light-emitting elements are located at positions different in a Y direction from positions of the plurality of light-receiving elements.

Abstract: A light-emission-side prism accommodates a light-emitting element and is disposed in a light-emission guide hole extending in a light-emission axis direction. A light-reception-side prism accommodates a light-receiving element and is disposed in a light-reception guide hole extending in a light-reception axis direction. The light-emission-side prism has a total-reflection surface that causes light from the light-emitting element to be directed in the light-emission axis direction and a lens surface that causes light emitted from the total-reflection surface to be condensed. The light-reception-side prism includes a lens surface that causes scattered light entering from a smoke monitoring area in the light-reception axis direction to be condensed and a total-reflection surface that causes light condensed by the lens surface to be directed toward the light-receiving element.

Abstract: A microscopic object detection system includes a collecting kit and a detection device. The collecting kit has a thin film for converting light into heat and is configured to be capable of holding a sample on the thin film. The detection device detects a plurality of microscopic objects in the sample by collecting the plurality of microscopic objects dispersed in the sample with the collecting kit. The detection device includes a laser module, an optical receiver, and a controller. The laser module emits a laser beam with which the collecting kit is irradiated. The optical receiver detects the laser beam from the sample held by the collecting kit and outputs a detection signal thereof. The controller calculates an amount of the plurality of microscopic objects collected in the sample based on a change of the detection signal over time.

Abstract: A method of collecting resin beads includes first to fourth steps. The first step is a step of preparing a sample on a thin film provided on an upper surface of a substrate. The second step is a step of irradiating the thin film with a laser beam and a laser beam with the laser beam and the laser beam being distant from each other. The third step is a step of producing a microbubble at a position irradiated with the laser beam and producing a microbubble at a position irradiated with the laser beam, by heating the sample by irradiation with the laser beams. The fourth step is a step of collecting a plurality of resin beads in a region between the microbubble and the microbubble by producing convection of the sample in a direction perpendicular to a direction of alignment of the microbubble and the microbubble.

Abstract: A laser module includes a plurality of light emission regions and the plurality of light emission regions emit a plurality of laser beams. An optical waveguide and a lens condense the plurality of laser beams to an identical focal point. An adjustment mechanism is configured to adjust relative positional relation between the sample stage and a condenser lens (the optical waveguide and the lens). A controller is configured to switch between a single-point irradiation mode and a multi-point irradiation mode. The single-point irradiation mode refers to a mode in which the adjustment mechanism is controlled such that the focal point of the plurality of laser beams falls on the thin film. The multi-point irradiation mode refers to a mode in which the adjustment mechanism is controlled such that the focal point does not fall on the thin film.
