Abstract: The present embodiments relate to a modular system to sort and analyze melee sized gemstones in an automated manner. The system can use a rotating tabletop design to separate gemstones for individual analysis and sorting. For instance, a feeder subsystem can obtain gemstones, and a singulation subsystem can orient the gemstones for further processing. The gemstone can move between subsystems due to the rotation of the table. A set of metric subsystems disposed about the table can process aspects of the gemstone to derive metrics for the gemstone. Further, a sorting subsystem can sort the gemstone into a corresponding bin based on the derived metrics for the gemstone.

Abstract: Systems and methods used to illuminate samples are disclosed. An illumination system includes a stage to support a sample thereon, a first electromagnetic (EM) radiation source to provide first EM radiation, a second EM radiation source to provide second EM radiation, and optical equipment to combine at least a portion of the first EM radiation with at least a portion of the second EM radiation to provide combined EM radiation to the stage to illuminate the sample. A method of illuminating a sample includes illuminating a first input of a dichroic beam splitter with white light from a white light emitting diode (LED), illuminating a second input of the dichroic beam splitter with ultraviolet (UV) light from a UV LED, and directing combined light from an output of the dichroic beam splitter toward the sample.
