Abstract

A detection system is described allowing scanning of an excitation irradiation beam over a substrate (8) for detecting luminescence sites. The scanning thereby is performed by using an optical deflector (5) for varying an angle of incidence of the excitation irradiation beam on a single focusing element (7) on an irradiation path between the deflector (5) and the substrate (8). By varying the angle of incidence on the single focusing element (7), the focus point of the excitation irradiation beam is shifted in the focal plane of the focusing element (7), where the substrate (8) is positioned. The latter allows fast scanning of the excitation irradiation beam. In a preferred embodiment, an additional scanning motion in a substantially different direction is furthermore superimposed, resulting in the possibility for scanning an appropriate area of the substrate (8). The additional scanning motion may be obtained using a split optics system, whereby substantially only the single focusing element (7) and the optical deflector (5) are moved with respect to the substrate (8), whereas other optical components typically are fixed with respect to the substrate (8) during the scanning.
