OPTICAL SYSTEM FOR CHEMICAL AND/OR BIOCHEMICAL REACTIONS

摘要

PROBLEM TO BE SOLVED: To provide a method for simultaneously distinguishing and detecting different wavelengths of light emanating from a number of different reaction vessels.SOLUTION: An apparatus for detecting spectra in light emanating from chemical or biochemical reactions occurring in at least one reaction vessel (3) of a plurality of reaction vessels is disclosed. Each reaction vessel (3) has a receptacle portion having an emitting area from which light can emanate. The apparatus includes a masking element (5) having an array of apertures (6) through which light from each reaction vessel (3) can escape, and a plurality of light waveguides (7) are arranged to guide light from the apertures (6) of the masking element (5) to a light dispersing device (8) for dispersing the light from each waveguide (7) into a dispersed spectrum. A light detecting device (10) detects specific spectra in the dispersed spectra of light substantially simultaneously.SELECTED DRAWING: Figure 1
