A method and apparatus for determining a cell volume of a red blood cell is provided. The method includes the steps of: a) depositing a sample into an analysis chamber, the chamber defined by an first panel interior surface, a second panel interior surface, and a known or determinable height, which height is such that at least one red blood cell subject to a sphering agent assumes a partially compressed spherical shape in contact with the interior surfaces; b) imaging the at least one partially compressed spherical red blood cell contacting the interior surfaces, and producing image signals; c) determining a radius of the partially compressed spherical red blood cell from the image signals; and d) determining a volume of the imaged red blood cell using the determined radius.

Method and apparatus for determining mean cell volume of red blood cells

A line confocal microscope system, comprising an illumination system with a source of collimated light and a line forming optics arranged to provide a line shaped illumination area to be scanned over a sample, an image receiving system, and two or more objective lenses that are interchangeable in the optical path to provide different magnification, wherein the objective lenses have different aperture diameters, and the illumination system comprises a beam shape transformer arranged in between the source of collimated light and the line forming optics to selectively transform the cross-sectional shape of the collimated beam of light transmitted to the line forming optics to a predetermined shape in response to the back aperture diameter of the objective lens that is arranged in the optical path.

A method and an apparatus for imaging a biologic sample is provided. The apparatus includes at least one light source, at least one lens array, at least one image detector, a positioning system, and an image processor. The lens array has a plurality of lengthwise extending rows, which rows are successively arranged in a widthwise direction. Each row has a plurality of micro lenses, with each micro lens having a resolution field. Each micro lens is adapted to receive light from the illuminated region of the sample and to produce a beam of light. Each row includes a first micro lens and the first micro lens in each successive row is offset from the first micro lens in the previous row by a predetermined amount extending in the lengthwise direction. The offset between successive rows aligns the resolution fields of the micro lenses to collectively create a continuous resolution field across the length of the lens array. The positioning system moves the lens array and image detector relative to the sample, or vice versa, or both. The image processor produces an image signal indicative of the illuminated region of the sample produced from data signals from the image detector.
