Abstract

A method for identifying images of wells in an image of a well-bearing object such as multiwell plates or picowell carriers is disclosed using optical properties of the well-bearing object. An observation component, such as a camera, is used to approach focus of a focal point of a feature of the well-bearing component such as a well-bottom or well-wall or intersection of wells. An image of the focal point is acquired. The image of the focal point is then used as a reference point or used to define a reference point from which to identify the image of the well in the image of the well-bearing component and from which to delineate the borders of the well. In an aspect of the present invention, the well-bearing object is used as a wave-guide. Light escaping from a surface of the well-bearing object through discontinuous features such as well-intersections and well walls is used to delineate the borders of wells on the well-bearing object. Also disclosed is a multiwell device and a use thereof for the study of cells wherein bottoms of the wells are configured to focus light emitted from within a well and passing through the well bottom.
