Abstract:
1. A system for alternatively measuring epi-fluorescence or luminescence produced by samples in a sample plate, comprising a first presentation plate for measuring epifluorescence and having an array of silica optical fibres of numerical aperture (NA) of the order of 0.2 for presenting to at least some of the samples in the sample plate at a small spacing therefrom to convey epi-fluorescence from the samples to a CCD camera, and a second presentation plate for measuring luminescence and located immediately adjacent to or in contact with the sample plate, the second presentation plate presenting the ends of a matching array of optical fibres to at least part of the array of samples, each such fibre having an NA greater than 0.2, and the said array of optical fibres from the second plate conveying luminescence emitted by the samples to a CCD camera.
