20100252748 | Multi-Purpose Measurement System - The invention relates to an apparatus for optically analysing samples contained in sample sites of a sample holder, the apparatus comprising a first light source and at least one second light source, a monochromator having an input to which first light source is optically connected or connectable and an output for monochromatized light, light guiding means for guiding light originating from the first and from the at least one second light sources to the sample sites, and a detector for detecting light from the sample sites. According to the invention, the apparatus further comprises a light relay comprising a first input optically connected to the output of the monochromator, at least one second input optically connected or connectable to a second light source such that the light from the second light source by-passes the monochromator, and a first output for guiding light from selected input of the light relay to the sample sites. By means of the invention, a versatile sample analyser can be achieved in a cost-effective manner. | 10-07-2010 |
20110049385 | Sample Measurement System - 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 having narrow wavelength bands, means for further limiting wavelength bands of the light emitted by the individual light sources, means for guiding the reduced-wavelength light to the sample sites of the sample holder, and a detector for detecting light from the sample sites. According to the invention said means for further reducing the wavelength bands emitted by the individual light sources 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. | 03-03-2011 |

20090130772 | Apparatus and method for collecting data on light-emitting reactions - The invention concerns an apparatus and a method for collecting data on a set of light-emitting molecular reactions. The apparatus comprises a holder for a reaction vessel comprising a plurality of reaction spaces containing first reaction substance, feeder for supplying second reaction substance to said reaction spaces for initiating said reaction set, and a plurality of light detectors for measuring light emitted from said reaction spaces in synchronized relationship with said feeding. According to the invention, at least two of said light detectors are arranged on opposing sides of the reaction vessel and being adapted to simultaneously measure different properties of the reaction set, that is, different wells or wavelengths, for example. The invention allows doubling the measurement speed in aequorin-based intracellular Ca-measurements. | 05-21-2009 |
