Abstract:
1. Apparatus for monitoring light emanating from an array of reaction vessels in which a chemical or biochemical reaction is occurring, said apparatus comprising: an array of reaction vessels, each reaction vessel comprising a receptacle portion having an interior volume in which a chemical or biochemical reaction may occur and in which volume the light may be produced, the reaction vessel having an emitting area from which at least part of the produced light can emanate; a light detecting device for detecting one or more wavebands of at least part of the light produced in the interior volumes of all of the reaction vessels where light is produced; a first set of light waveguides comprising at least one light waveguide for each reaction vessel in the array of reaction vessels, each light waveguide arranged to guide at least part of the light produced in the interior volumes of a respective reaction vessels and emanating from the respective reaction vessel to the light detecting device, whereby at least a part of the produced light emanating from all of the reaction vessels where light is produced is detected substantially simultaneously by the light detecting device, each light waveguide having a first end arranged adjacent a corresponding emitting area of a respective reaction vessel, and a second end arranged for providing at least part of the light emanating from the respective reaction vessel to the light detecting device, wherein the first ends of the first set of light waveguides are arranged in an array arranged adjacent the array of reaction vessels; at least one excitation light source for providing excitation light; and a second set of further light waveguides for guiding excitation light from the at least one excitation light source to all of the reaction vessels substantially simultaneously, the second set of further light waveguides comprising at least one further light waveguide for each reaction vessel in the array of reaction vessels, each further light waveguide having a first end arranged adjacent a respective reaction vessel and a second end arranged for receiving at least part of the light from the at least one excitation light source.
