Abstract
The invention relates to a surface plasmon resonance spectrometer comprising a radiation source that emits substantially monochromatic radiation, a sensor surface, an optical arrangement for lighting the sensor surface by the radiation emitted from the radiation source such that surface plasmons can be created in the sensor surface, a detector having a plurality of image elements and observation optics for depicting the radiation reflected by the sensor surface on the detector, characterized in that the resolution capability of the observation optics and of the detector is larger than the resolution that can be obtained by the deflection-limited radiation source.
