Abstract
The invention relates to a set-up of measuring instruments for the parallel readout of SPR sensors. The aim of the invention is to provide a measuring arrangement for the parallel readout of a plurality of SPR sensors, wherein the readout process should be terminated within an integration period of less than 30 minutes. To this end, a wavelength-selective component ( ) and an optical imaging system (L , L ) are arranged downstream of a light source ( ). Said optical imaging system (L , L ) is in such a manner that at a first wavelength it guarantees a parallel illumination of the light entrance sides of the waveguides ( ) which are provided with SPR-compatible sensor zones, and that the light emerging from the individual light waveguides ( ) may simultaneously be imaged onto a CCD chip ( ) via an optical system (L ) in such a way that the light emerging from each individual light waveguide ( ) is respectively detectable by several adjacent CCD pixels of the CCD chip ( ), and from these pixel areas a respective light intensity value is calculable by means of image processing software, and, after data storage of an intensity value, a set wave length and coordinate in the waveguide array ( ), an adjustment of the wavelength-selective assembly ( ) to a second, arbitrarily providable, further light wavelength is performable by means of a computer ( ) via a control line ( ).
