Abstract
Optical detection apparatus for chemical analyses of small volumes of samples has light sources (21) to emit induction light, a measuring cell (7) for the sample, photoelectric sensing elements (22) to receive light coming form the sample in the measuring cell (7), as well as beam-conducting means for the induction light or the light from the sample. In the apparatus, several essentially planar, laminar components (2-7) are arranged in a sandwich structure, whereby the components (2-7) contain the light sources (21), the measuring cell (7), the photoelectric sensing elements (22), and also the beam conducting means.
