OPTICAL SYSTEM FOR CHEMICAL AND/OR BIOCHEMICAL REACTIONS

摘要

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 may include a masking element (5) having an array of apertures (6) through which light from each reaction vessel (3) can escape. A plurality of light waveguides (7) are arranged to guide light from the apertures (6) in the masking element (5) to a light detecting device (10) for detecting the spectra of light substantially simultaneously. One or more further light waveguides (31) may be provided for each reaction vessel (3) for directing excitation light from one or more excitation light sources (32, 33) to the reaction vessels (3).
