Abstract:
1. A scanner comprising: an illumination source; at least one substrate containing a sample that is selectively illuminated by the illumination source; a receiver that receives light from the sample; optics that direct light from the illumination source to the substrate and back from the substrate to the receiver; a processor that adjusts a gain level of the receiver and controls the optics and the illumination source to effectuate a scan of the sample on the substrate; wherein the processor is adapted to initiate the optics, illumination source, and receiver to effectuate an under-sample scan at an initial gain level and determine an illumination level read by the receiver; wherein the processor is adapted to adjust the gain level of the receiver based on the determined illumination level; and wherein the processor is adapted to initiate the optics, illumination source, and receiver to effectuate a final scan at the adjusted gain level if the adjusted gain level is within a predetermined range.
