Abstract
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.
