Abstract
A fluorescence measuring unit comprising a monochromatic light source (13), a detector unit (23a, 23b), an excitation beam (13a) going from the light source (13) to the spot (18), an emission beam going from the spot (18) to the detector unit (23a, 23b) and an acousto optic tuneable filter (AOTF) (12), arranged in a non-collinear mode, and such that the excitation beam path and the emission beam path coincide but propagate in the AOTF in opposite directions. An arrangement comprising two laser sources (27) defining two beam paths leading to a common beam path (31) with the features that: a) said laser sources have polarisation planes perpendicular to each other and b) a non-collinear AOTF (29) is placed in the conjunction of said two beam paths and oriented such that, when tuned to the respective wavelength of the laser light from the respective laser source, the laser light from the two sources will pass and exit the second AOTF (29) in one and the same beam path (31).
