Abstract
An optical system with an optical fibre bundle 11 having a hollow input terminal 13 for measuring the degree of polarisation of the polarised light from fluorescence in instruments for chemical/clinical analyses on microplates is described. The system substantially comprises: a light source 1 of low power and low intensity, interference filters 3, 9 for selection of the excitation and emission wavelengths, a rotating polariser 5 on the excitation channel and a fixed polariser 12 on the emission channel, separate optics to guide the excited polarised light, an optical fibre bundle 11 designed to collect the polarised light from fluorescence back-diffused by the sample contained in a well P in microplate, a photomultiplier PMT for reading the modulated light signal. <IMAGE>
