Abstract
A line scanning arrangement for imaging microarrays includes a line illuminator that converts output from one or more lasers to a radiation line. The laser output passes through a single mode fiber and a module that converts the laser light to the radiation line. The line is confocally directed to sites on the microarray, and retrobeams returned from the sites are collected on an imaging detector. The microarray is moved in the imaging apparatus so as to progressively illuminate an array or matrix of sites for imaging.
