Figure 1

Side view of the imaging apparatus. A SLR camera is mounted on posts in front of the sample, with a dichroic emission longpass filter placed between sample and lens. Two blue LED sources (at 45°angle from the lens-sample path) provide homogeneous excitation light. The cotton boll sample is placed on a rotary stage to allow images to be taken from all sides. A non-fluorescent black cardboard backdrop blocks scattered light and background fluorescence.
