Abstract:
The invention relates to an apparatus and method for optically analysing samples contained in sample sites of a sample holder by means of fluorescence. The apparatus comprises a first light source comprising a plurality of individual light sources (41, 42, 43) having narrow wavelength bands, means (45) for further limiting wavelength bands of the light emitted by the individual light sources (41, 42, 43), means (46) for guiding the reduced-wavelength light to the sample sites (49) of the sample holder, and a detector for detecting light from the sample sites (49). According to the invention said means (45) for further reducing the wavelength bands emitted by the individual light sources (41, 42, 43) comprise a wavelength-tunable single monochromator. The invention allows manufacturing of a microplate reader having the capability for fluorescence measurements at a continuous wavelength range, while maintaining the cost of the device at a reasonable level.

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.
