conducts scientific research and high-tech developments in the field of natural and technical sciences, development and production of the AVRORA DIAMOND INSPECTOR (ADI) line of devices for identification and technological use of diamonds.

INNOVATIVE PORTABLE DETECTOR TO IDENTIFY PRECIOUS STONES

The ADI-S2 photoluminescence spectral analyzer is an innovative portable detector with a remote active optical probe designed for spectral measurements of the photoluminescence of diamonds, polished diamonds, and other precious minerals. The device allows you to explore both individual crystals and other objects included in jewelry. The result of the work of ADI-S2 is the determination of the sample belonging to diamonds of natural or synthetic origin (grown using HPHT or CVD technology), the isolation of crystals of moissanite, cubic zirconia, and imitators, as well as the determination in automatic and/or manual modes of other features of the samples, such as synthetic treatment, irradiation, etc.
The ADI-S2 can be used both completely offline with the results displayed on the display, and in conjunction with a PC, which allows the operator to independently explore the spectra. In the automatic mode of operation of the device, the operator is not required to have special knowledge and training for the full use of the device. To excite luminescence, the ADI-S2 uses three independent sources with different energies, including the LWUV excitation source, which causes effective photoluminescence of natural diamonds with characteristic optical centers, which significantly expands diagnostic capabilities and significantly reduces identification time.
The integral set of parameters obtained during measurement allows the identification of samples by belonging to a particular type.

* The technical specifications of the device can be changed or adapted to the customer's requirements.

Professional instrument for the analysis of luminescence plots with wide optical capabilities. The device is designed to study the luminescence plots of natural diamonds, polished diamonds, diamond plates, crystals of synthetic (CVD or HPHT), as well as imitators and precious minerals of all shapes and sizes (up to 25mm). To excite the photoluminescence of samples, three independent radiation sources are used in the device: 365, 254 and 225 nm, and the first two have adjustable intensity. The optical system of the device allows you to analyze both the entire sample as a whole and its individual areas in optical magnification. The device and software have implemented functionality for full-fledged operator work with scaling, positioning, exposure, colors and other features.

IDENTIFIES:
— Natural diamonds.
— Treated diamonds.
— Lab-grown diamonds (CVD, HPHT).
— Allows a detailed study of the luminescence pattern.
— Sizes of analyzed samples starting from 0.005 carats.
— It is possible to analyze the luminescence of other minerals.
— The luminescence pattern is displayed on the monitor screen.

Identification is performed by the operator on the monitor screen by analyzing fluorescence and phosphorescence patterns during excitation in the optical bands: LWUV, SWUV and EGUV.
