Abstract:
An apparatus for detecting light transmitted from a substrate having a plurality of sample sites, the apparatus comprising:a stage for supporting the substrate, the stage being configured to move the substrate in a first direction so that the sample sites pass sequentially through an examination region delimited by a detection initiation position and a detection termination position;a detector configured to detect light;an optical relay structure configured to transmit light from a sensed volume within the examination region to the detector, the sensed volume being smaller than the examination region; andan automated scanning mechanism configured to move the sensed volume in the first direction between the detection initiation position and the detection termination position;wherein the sensed volume tracks a first sample site as it moves between the initiation position and the termination position, so that light transmitted by the first sample can be detected by the detector.
