Abstract: A luminometer includes a movable carrier carrying a number of luminescence collectors arranged in an array for simultaneously detecting the same number of samples received in multiple wells defined in a microplate. An optic fiber optically couples each luminescence detector to an associated charge-coupled device whereby a luminescence signal emitted from each sample is transmitted to the charge-coupled device and converted thereby into a corresponding electric signal. The charge-coupled devices are isolated from each other by partitions, which eliminate undesired interference among the luminescence signals transmitted to the charge-coupled device. A driving unit is provided to move the carrier between rows of the wells defined in the microplate.
