Abstract:
A system for optically scanning a region comprising a sample of which a chemical composition is to be determined, comprising: a pulsed laser source for emitting a pulsed laser beam; a focusing device for adjusting the position of the waist of the laser beam along an optical path of the laser beam; a deflector for adjusting a propagation direction of the laser beam to a given direction; a controller for varying, via the beam deflector, the propagation direction of the pulsed laser beam according to a predefined beam path and varying, via the focusing device, the given position of the waist of the laser beam along the optical path; and a photodetector for detecting light emitted by a plasma created when a given one of laser pulses has an irradiance is greater than a breakdown threshold, the detected light being indicative of the chemical composition of the sample.
Abstract:
An apparatus (12) for receiving an analyte comprises two opposing housings (16, 18) that clamp onto a substrate (14). One of the housings (18) includes passageways that deliver the analyte and optical signals to the substrate (14). Another one of the housings (16) includes passageways that allow optical signals, which have passed through the substrate (14), to travel to photometric sensors (88) which may be used to study the analyte or its effects. The apparatus (12) may include a light guide (74) that uniformly distributes light from a plurality of point emitters to multiple areas of the substrate (14). The apparatus (12) may include an actuator assembly (20) that opens and closes the two housing (16, 18) to allow for installation and removal of the substrate (14). The substrate (14) may be carried in a cartridge (160) that is removable from the two housings (16, 18).
Abstract:
An inspection system having a light source, a mirror sensor, and an image sensor. The mirror assembly is aligned with the camera; the light is reflected from the container to the camera, and the camera creates multiple images of the container at a viewing angle. The multiple images are analyzed to detect defects.

The instrument may include a light source (11) for emitting a source beam, a first means (7) disposed to be receptive of the source beam, a primary focusing means (3) disposed to focus the excitation beam simultaneously into a plurality of suspensions and being receptive of and passing emission beams, a second means (8) disposed to be receptive of emission beams, an emission focusing means (10) for focusing emission beams, a detector, and a processing means for computing concentration of DNA. The optical system being arranged without a beam splitter (6) but with one or more folding mirrors (5), and with excitation and emission beams being on slightly different optical paths angularly.
Abstract:
An apparatus for simultaneously measuring whiteness and coating amount, according to one embodiment of the present invention, comprises: a light-emitting unit arranged at a predetermined distance from a test piece and irradiating the test piece with light; a filter unit arranged between the light-emitting unit and the test piece and allowing either an infrared ray or a visible ray to selectively pass therethrough; a detection unit arranged at a predetermined distance from the test piece and detecting either the infrared ray or the visible ray to be reflected from the test piece; and a calculation unit connected with the detection unit, calculating the coating amount according to the amount of the infrared ray detected by the detection unit, and calculating the whiteness according to the amount of the visible ray detected by the detection unit. Since the whiteness and the coating amount can be measured by the apparatus for simultaneously measuring the whiteness and the coating amount according to one embodiment of the present invention, work efficiency is increased and capital expenditure for equipment can be reduced.

Abstract:
A sample analyzer has an illuminator for illuminating an assay sample to cause luminescence, and a support for a sample vessel containing the assay sample. The support is adapted to position the assay sample proximate the illuminator. A detector is positioned along an optical axis extending from the illuminator, through the positioned assay sample, to the detector, so as to detect the luminescence from the assay sample. A reflector is removably disposed between the illuminator and the assay sample so as to reflect a portion of the luminescence back through the positioned assay sample toward the detector.
