Abstract
Systems and methods here may be used for capturing and analyzing spectrometer data of multiple sample gemstones on a stage, including mapping digital camera image data of samples, for both reflective and transmission modes.
Claims17
A system for reflectance spectrometer analysis, the system comprising:
- a computer with a processor and memory, in communication with a spectrometer and a light source;
- a reflectance subsystem including,
- a bifurcated reflectance subsystem fiber bundle with a probe end mounted on a reflectance subsystem bracket frame connected to a vertical track, wherein the vertical track configured to allow the reflectance subsystem probe end to raise and lower over a reflectance subsystem stage, wherein the stage configured to hold a sample gemstone table-side down;
- wherein a first of the bifurcated reflectance subsystem fibers is in communication with the light source and a second of the bifurcated reflectance subsystem fibers is in communication with the spectrometer.
