  • Fluorescence-measuring system
    Patent number: 6985225
    Abstract: The invention relates to a fluorescence-measuring system as can be employed for high-throughput screening in drug development. The arrangement for fluorescence excitation contains a two-dimensionally extended sample-receiving device and at least two illumination sources for exciting the fluorescence of the samples. The illumination sources are extended linearly and arranged in such a way that the illuminated area of the sample-receiving device is homogeneously illuminated directly or via deflecting mirrors at an opening angle of ?30°.
