Abstract
A fluorescence imaging assembly including an imaging apparatus having an enclosure wall defining a view port into a light-tight imaging compartment thereof. A specimen platform is positioned in the imaging compartment having a support surface facing toward the view port. An illumination assembly includes a light source and a frame disposed in the imaging compartment. The illumination assembly is positioned proximate to and substantially peripherally encircling the view port. A bundle of fiber optic strands extends into the imaging compartment wherein proximal ends of the strands are in optical communication with the light source and distal ends thereof terminate at the frame to emit a conical directional beam of light onto the specimen platform. The distal ends of the fiber optic strands are sufficiently spaced peripherally about the view port such that the plurality of directional beams collectively illuminate the specimen platform in a substantially uniform manner.
