Abstract

An apparatus that automatically captures, stores and analyzes images of crystallization experiments contained in a number of crystallization plates. The apparatus includes a plate nest capable of accommodating protein crystallization plates of a plurality of different types, image acquisition optics, including an objective lens and an image capturing device, for focusing an image of a crystallization well, a light source including a bright field illumination device and a dark field illumination device, a nest positioning controller for moving the position of the plate nest with respect to the image acquisition optics to align various selected wells with said objective lens for imaging of the content of the wells. A database stores experiment information associated with each of the crystallization plates, the experiment information including identification of specific crystal forming parameter values, each of the crystallization plates is identified in said database by a unique identification code. A crystallization imaging controller controls crystallization imaging by retrieving the experiment information for each crystallization plate inserted into the apparatus, and controlling the nest positioning controller and the image acquisition optics in accordance with the retrieved experiment information. The apparatus captures multiple images of each crystal site using different light source and polarization conditions, and processes the multiple images to form extended fused images of each crystal site.
