摘要： Systems and methods here may be used for a setup of image capturing of a gemstone, such as a diamond, exposed to different light sources. Some examples utilize a setup that both sends light and captures the image through multiple dichroic beam splitters at pre-selected timing. The multiple light source and multiple dichroic beam splitter arrangement allows for multiple gemstones to be analyzed using multiple methods with minimal moving, changing, or adjusting the equipment for different samples.

摘要： Systems and methods here may be used for automated capturing and analyzing spectrometer data of multiple sample gemstones on a stage, including mapping digital camera image data of samples, applying a Raman Probe to a first sample gemstone under evaluation on the stage, receiving spectrometer data of the sample gemstone from the probe, automatically moving the stage to a second sample, using the image data, and analyzing the other samples.

摘要： Systems and methods here may be used for a setup of fluorescence image capturing of a gemstone, such as a diamond placed on a flat stage. Some examples utilize a setup that both sends light and captures the image from the table side of the gemstone by passing ultraviolet (UV) light between 10 nm and 400 nm to the gemstone and capturing the excited fluorescence image for analysis through a dichroic beam splitter. In some examples, the cutoff is 300 nm. The dichroic beam splitter arrangement allows for the camera to focus on the same interface of the stage and gemstone over and over for ease of use and without moving, changing, or adjusting the equipment for different samples.
