Abstract
A Surface Plasmon Resonance (SPR) biosensor system comprising: a SPR sensor surface, an illumination unit arranged to direct a wedge shaped beam of light at a line shaped detection area on the SPR sensor surface transverse to the direction of propagation of light, and a detection unit with detection optics for directing light reflected from the SPR sensor surface onto a two-dimensional optical detector unit such that the angle of reflection is imaged along one dimension and the width of the detection area along the other, wherein the illumination unit is arranged to selectively direct the wedge shaped beam of light at two or more spaced apart line shaped detection areas on the SPR sensor surface transverse to the direction of propagation of light.
