Apparatus for fluorescent imaging of cotton bolls. The sample is placed on a rotary stage (A) to allow the acquisition of multiple images to cover the entire surface. A light-emitting diode array (B) provides ultraviolet excitation light. Fluorescent emission passes through a longpass filter (C) that blocks UV light and reaches the SLR camera (D).
