Abstract

In a luminescence detecting apparatus and method for analyzing luminescent samples, luminescent samples are placed in a plurality of sample wells in a tray, and the tray is placed in a visible-light impervious chamber containing a charge coupled device camera. In the chamber, light from the luminescent samples pass through a collimator, a Fresnel field lens, an infrared filter, and a camera lens, whereupon a focused image is created by the optics on the camera. The use of an infrared filter suppresses stray IR radiation resulting from plate phosphorescence (which can result in abnormally high backgrounds and/or alteration of the image received by the camera).
