Sample measurement system

摘要

The invention relates to an apparatus and method for optically analyzing 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.

1. An apparatus for optically analyzing samples contained in sample sites of a sample holder by means of fluorescence, comprising
a light source comprising a plurality of individual light sources having narrow wavelength bands, a light source selector for selecting light from one of the individual light sources by selecting and connecting an optical fiber with light from one of said individual light sources, a wavelength-tunable single monochromator for further reducing the wavelength band of the light emitted by said selected individual light source, means for guiding the reduced selected individual light source light to the sample sites of the sample holder, and a detector for detecting light from the sample sites.
