Patent ID: 10823680

Abstract:
A diamond identification apparatus relates to the field of examining natural and synthetic diamonds. The claimed apparatus for identifying a cut diamond comprises a measurement location with a measuring aperture at which the cut diamond to be examined is fixedly positioned; a movable optical system including a spectrometer, two sources of radiation at wavelengths of 250-280 nm and 350-380 nm, respectively, said two sources of radiation and the spectrometer being connected to the measurement location by optical fibres for inputting radiation into the cut diamond and by an optical fibre for outputting radiation from the cut diamond; and also a source of laser radiation at a wavelength of 532 nm and a microcontroller, wherein the cut diamond is positioned at the measurement location in such a way that the table of the diamond faces the measuring aperture of the measurement location, and the culet of the diamond is situated directly above the measuring aperture to which the optical fibres for inputting radiation and the optical fibre for outputting radiation are connected, and wherein the microcontroller is configured to control the alternate operation of the sources of radiation in a set time sequence, the movement of the optical system to allow the input of radiation into the cut diamond, and the processing of the spectrometer data.
