Abstract:
This detection device has a holder, light irradiation unit, angle adjustment unit, light receiving sensor, light receiving optical system, optical filter, and a control unit. The light receiving optical system guides light from a detection chip to the light receiving sensor. The optical filter is disposed in the light receiving optical system, blocks a part of plasmon scattered light, and passes, out of the light emitted from the detection chip, a part of the plasmon scattered light, and fluorescence emitted from a fluorescent material. The light receiving sensor detects the fluorescent light, and the part of the plasmon scattered light, which have been emitted from the detection chip and passed the optical filter. On the basis of the detection results of the plasmon scattered light, the control unit controls the angle adjustment unit, and adjusts the incident angle of the excitation light to a predetermined incident angle.

Abstract:
The invention relates to the detection of sparks in a channel where material flows. A spark sensing device is positioned in connection with channel where material flows in a flowing direction. The spark sensing device comprises a sensor element and an optical element that transfers a radiation of a spark to the sensor element. The optical element is made of optically transparent material. The optical element is such that it shapes the collection beam of the sensor element to be asymmetrical whereby the viewing angle of the sensor element is wider in a direction transverse to the flowing direction than in the flowing direction.

Abstract:
A method and an apparatus for imaging a biologic sample is provided. The apparatus includes at least one light source, at least one lens array, at least one image detector, a positioning system, and an image processor. The lens array has a plurality of lengthwise extending rows, which rows are successively arranged in a widthwise direction. Each row has a plurality of micro lenses, with each micro lens having a resolution field. Each micro lens is adapted to receive light from the illuminated region of the sample and to produce a beam of light. Each row includes a first micro lens and the first micro lens in each successive row is offset from the first micro lens in the previous row by a predetermined amount extending in the lengthwise direction. The offset between successive rows aligns the resolution fields of the micro lenses to collectively create a continuous resolution field across the length of the lens array. The positioning system moves the lens array and image detector relative to the sample, or vice versa, or both. The image processor produces an image signal indicative of the illuminated region of the sample produced from data signals from the image detector.
Abstract:
There is disclosed a double beam differential fluorimeter requiring no light chopper and characterized by unusually small cell volume and high optical efficiency. The instrument comprises a bifurcated conical light tunnel having highly reflecting internal surfaces. A transparent tube passes through each side of the bifurcated light tunnel, one for containing a sample fluid, the other for containing a reference fluid. A light source directs ultraviolet radiation into the large end of the conical tunnel. A pair of photodetectors are positioned at the small end of the tunnel, together with an ultraviolet blocking filter. Each detector is responsive, respectively, to fluorescence from the sample and reference fluids. An electrical bridge circuit compares the intensities of the fluorescence derived from the sample and reference fluids.

There is set forth herein a light energy exciter that can include one or more light sources. A light energy exciter can emit excitation light directed toward a detector surface that can support biological or chemical samples.
Abstract:
The present invention provides a multi-channel fluorescence detecting system for detecting a plurality of fluorescence labeled analytes. The multi-channel fluorescence detecting system comprises a light source, a light filter device, a dual branch light guide tube, and a detector. The light source comprises a plurality of sub light sources for respectively providing an excitation light. The plurality of sub light sources are a plurality of single color Light emitting diodes (LEDs) which can be selectively turned on or off. The light source generates a plurality of lights with full width at half maximum (FWHM) wavelengths formed in a non-overlap manner. With the disposition of the plurality of sub light sources, the accuracy for detecting the specific analytes is raised, the light flux with a specific wavelength band is effectively raised (without raising the light flux of the full wavelength band), the structure is simplified, and the manufacturing cost is decreased.
