Incident light redistribution to compensate for radial gradient in detector

Abstract From the Canadian patent

Nonuniformities in the efficiency of detection of individual fluorescing reaction mixtures in a well plate with a two-dimensional array well array are corrected. The nonuniformities arise both from the stimulation pattern and the detection pattern, and are corrected by adding additional segments to a pair of segmented mirrors. The additional segments are oriented to direct light to the outermost reaches (i.e. the four corners) of the array and thereby produce a stimulation pattern that has a greater intensity in the outermost regions. This compensates for a radial decline in the efficiency of the detector in detecting the emissions from the well plate the radial decline , being an …
