The invention relates to an illumination module for color display, preferably for use in data or video projectors as well as rear projection television sets, in which the light from at least three luminescent diodes (LEDs) or LED arrays of the base colors red, green and blue is collimated at a point provided for connection to a display unit and ranged on an optical axis of the illumination module. An LED or an LED array of a base color with a beam path (Lr) oriented in the direction of the display unit is arranged on the optical axis of the illumination module. For the purpose of color mixing, the LEDs and LED arrays of the other base colors are attached in such a way tat their beam paths (Lg, Lb) are laterally input in sequence under input angles (&#x3b1;, &#x3b2;) of &#x3c;90 degrees into the beam path (Lr) of the first base color.

The invention relates to a surface plasmon resonance sensor for the simultaneous measurement of a plurality of samples present in fluid form. The aim of the invention is to provide such a sensor which can be arranged into a defined array and where the surface plasmon resonance sensors can be produced using technology which is simpler and more economical than those produced according to the prior art. To this end several strip-like optical wave guides ( ) are arranged on a planar support ( ) at a defined distance to each other in such a way that their front faces ( ) are flush with opposite sides ( ) of the planar support ( ). Each strip-like optical wave guide ( ) in a section which is to be brought into contact with the fluid samples has at least one thin metal layer ( ) which permits the excitation of surface plasmons. Means ( ) are provided for which separate the measurement zones of the individual thin metal layers ( ) from each other in such a way that each of the optical wave guides ( ) can be assigned to only one sample.
