A particle recovery device for recovering particles contained in a liquid sample, the particle recovery device comprising:

Particle recovery device and particle recovery method

A measurement device includes an acquisition unit and a calculation unit. The acquisition unit acquires a first image obtained by image-capturing liquid containing tangible components flowing through a flow path and a second image image-captured simultaneously with the first image and having an image-capturing magnification higher than the first image. The calculation unit sorts, by using clipped images obtained by clipping the tangible components included in the first image and the second image, the tangible components into different types, and that calculates, by using a total number of the tangible components clipped out of the first image and included in a specified category as well as a ratio of a number of each of the tangible components of the different types clipped out of the second image and included in the specified category relative to a total number thereof, the number of the tangible components included in the specified category.

Measurement device and measurement method

Detection and analysis of a tangible component in a sample are implemented at lower cost. Provided is an analysis apparatus including a flow cell which includes a flow path for a sample, a branch section configured to cause light having passed through the flow path to branch at least to a first optical path and a second optical path, a first imaging section and a second imaging section configured to capture images of the sample in the flow path by using the light in the first optical path and the light in the second optical path, and a controller configured to process the captured images. The first imaging section and the second imaging section capture images that have the same angle of view but have different characteristics.

Analysis apparatus and analysis method

A plurality of images of a sample are simultaneously captured at different focal lengths by a plurality of cameras. An analysis apparatus includes: a branch section configured to cause light passing through the sample containing a material component to branch off into a plurality of optical paths; a plurality of imaging devices for simultaneously capturing images of the sample in a flow path at different focal points by using the light caused to branch off into the plurality of optical paths; and a controller configured to process the captured images.

Analysis apparatus

Sensitivity is increased by enhancing the fluorescence collection efficiency while suppressing the increase in size of an objective lens. An objective lensis structured to have a convex lens partin a center portion and to have a truncated conical cylindrical bodyaround the convex lens part. Therefore, a fluorescence component b having too wide an emission angle to fit in the convex lens part, of fluorescence emitted from a sample, can be collected by total reflection on an outer peripheral surfaceof the cylindrical body. Thus, even light having too wide an emission angle to be collected by a normal convex lens can be collected. As a result, it is possible to suppress the increase in size of the objective lens, to enhance the fluorescence collection efficiency, and to prevent the S/N ratio from being decreased by the existence of undetected fluorescence that is blocked by a prism. This can realize a fluorescence information reading device having high sensitivity.

Fluorescence information reading device and fluorescence information reading method

A first lens configured to convert light from the objective lens into parallel light includes a concave lens part having a concave curved face in a center portion of a flat face, and a convex lens part having a convex curved face around a flat face. Further, the first lens includes first and second regions configured to diverge light through the flat face and the concave curved face and a third region configured to collect light through the convex curved face and the concave curved face. When the sample is on a sample table and sealed in a two-dimensional electrophoresis substrate, light totally reflected by a side surface of the objective lens enters the second region. In contrast, when the sample is directly on the sample table, the light enters the third region.

Optical unit, fluorescence detection device, and fluorescence detection method

A camera flash comprises a light guide arranged to extract light at least through one surface; and one or more light sources arranged, in use, to emit light into the lightguide. Each light source is an LED or a laser diode. The camera flash is connectable, in use, to drive circuitry, the drive circuitry being for driving the light source(s) to emit a pulse of light. The waveguide spreads out the light from the light source(s), so that a flash of light from the camera flash does not present a safety risk, while minimizing loss of the light from the light source(s). The camera flash can thus provide a high overall optical output, spread over an extended area (as defined by the waveguide). The lightguide may for example be disposed around a camera module of a mobile telephone camera.

Camera flash, a camera, and a method of generating a flash

An optical pickup device includes: a splitting section for splitting a beam; a light-receiving section for receiving the split beams. The light-receiving section includes: a tracking-use main light-receiving region and tracking-use sub light-receiving regions, and auxiliary light-receiving regions. Each of the auxiliary light-receiving regions receives only a light beam reflected off a recording layer other than a recording layer subjected to an information writing/reading process. A light-receiving area of each of the auxiliary light-receiving area is smaller than a light-receiving area of each tracking-use light-receiving region. Further, an optical pickup device includes: a splitting section for splitting a beam; and a light-receiving section for receiving the split beams. The light-receiving section includes a sub light-receiving regions for receiving tracking-use sub beams. The tracking-use sub beams are arranged so as not to allow entering of a focusing-use main beam reflected off a non-targeted recording layer.

Optical pickup unit and optical pickup device having same and information writing/reading device having same

An optical pickup device has a semiconductor laser emitting light which is in turn branched via a diffraction grating into at least three beams of light including a main beam and two sub beams which are in turn condensed via an objective lens on an optical disk at a guide groove and reflected by the optical disk to provide three reflections of light which are in turn received by detectors, each divided into two regions, respectively, to generate a tracking error signal. The diffraction grating is divided into three regions including a first region, a second region and a third region located intermediate therebetween, each having a periodical structure out of phase, the periodical structure having grating grooves in a direction determined depending on the phase of the second region to incline relative to a direction perpendicular to the guide groove of the optical disk.

Optical pickup device recording and/or reproducing information on and/or from a plurality of kinds of recording media

There is provided an optical pickup apparatus that can obtain a stable servo signal by reducing stray light generated by diffraction in a recording layer other than a recording layer on which light is condensed. A hologram element provided in an optical pickup apparatus for recording information onto a recording medium and/or reproducing information on the recording medium by use of light includes fourth and fifth divisions where at least first-order diffracted light among diffracted light beams obtained by reflection and diffraction on a recording layer other than a light-condensed recording layer on which light is condensed by an objective lens so as not to be directed toward first and second light-receiving elements for detecting focus position information and third to eighth light-receiving elements for detecting track position information.

Optical pickup apparatus

An optical pickup includes a hologram element. The hologram element is provided with a hologram pattern including a splitting section for focus which splits light used for the detection of an FES and a splitting section for tracking which splits light used for the detection of a TES. The splitting section for tracking is formed in a region excluding a region interposed between a first virtual straight line and a second virtual straight line. The first virtual straight line is drawn on the hologram element in parallel to an X direction and passes through an optical axis of reflected light entering the hologram element in a state where the objective lens is in a neutral position, and the second virtual straight line is drawn in parallel to the first virtual straight line, while being spaced at a distance d from the first virtual straight line.

Optical pickup

Regional borderlines that are the borderlines between the first region and the second region on a diffraction grating of an optical pickup partially overlap a group of y-axis parallel borderlines that are borderlines between pattern A and pattern B that are parallel to a direction parallel to the y-axis.

An optical pickup converts a laser beam from a semiconductor laser () into a parallel ray with a collimator lens (), and divides it into a main beam (), a sub-beam (+1st order component) (), and a sub-beam (&#x2212;1st order component) () with a gradient multiple-division type phase difference grating (). After passing through a beam splitter (), an objective lens () condenses the light beams on a track () of an optical disc (), and the reflected light that has passed through the objective lensis reflected at the beam splitter () and is guided into optical detectors (A,B, andC) by a condensing lens (). Accordingly, in a tracking error signal detecting method using the push-pull signals of the main beam and sub-beams, an offset produced by an objective lens shift or a disc tilt can be cancelled at low cost without lowering the efficiency of using light.

A low-cost, high-mass-productivity catalytic combustion apparatus having a construction that permits easy maintenance is realized. There is provided a catalytic combustion apparatus in which, by means of a combustion chamber having a fuel supply portion and a combustion air supply portion on the upstream side thereof and a combustion gas exhaust port on the downstream side thereof and a catalytic combustion portion with an upstream surface and a downstream surface provided in the combustion chamber, the upstream surface and the downstream surface being substantially parallel to each other, a fuel-air mixture supplied to the interior of the combustion chamber is caused to react to liberate heat. The catalytic combustion apparatus includes a heat exchange portion, which constitutes part of walls of the combustion chamber, and a fin-type radiant heat-receiving portion, which protrudes from the heat exchange portion into the combustion chamber and being provided in the vicinity of the catalytic combustion portion. In this catalytic combustion apparatus, the surface of the fin-type radiant heat-receiving portion and the surface of the heat exchange portion face in the same direction.
