Abstract
The sensor based on the surface plasma resonance phenomenon includes a light-transparent part 3, against which the surface of a material layer 4 lies, in which the surface is capable of resonating with electromagnetic radiation incident on it. Layer 4 on its opposite side can be brought into contact with the material being investigated. The wavelength of the light emitted from the same light source 1 is variable and the point of the light source from which the light beam is directed along a fixed path toward layer 4 is fixed relative to the surface of layer 4. An arrangement 8 to record the intensity value of the light reflected from the surface at different wavelengths is connected to detector 7 and connected to light source 1 is an arrangement for automatic scanning of a specified wavelength range at high speed, preferably in a second, by means of light source 1, which arrangement synchronously cooperates with the recording device 8. <IMAGE>
