Abstract
An apparatus and method for imaging a biologic fluid sample quiescently residing within a chamber is provided. The chamber includes a first panel and a second panel, between which the biologic fluid sample quiescently resides. At least one of the first and second panels is flexible. The chamber has one or more fields that are each defined by a cross-sectional area. The apparatus comprises a field illuminator, a chamber flattener, a positioner, and an image dissector. The field illuminator has an objective lens. The chamber flattener has a platen with a window and a cover plate. The chamber flattener is operable to cause the chamber to assume a substantially uniform Z-axis position for substantially all of the fields within the chamber. The positioner is adapted to position the objective lens and the chamber relative to one another. The image dissector is adapted to image the sample residing within the chamber.
