Optical sorter ASDI 500

The ASDI-500 is able to detect and extract synthetics and simulants as small as half a millimetre in diameter, at the astounding speed of 700 stones per hour. Developed to protect the integrity of the watch and jewellery industry, the ASDI-500 automatically sorts very large quantities of batches of round colourless polished melee, detects and extracts synthetics and simulants from among the natural diamonds. The ASDI-500 is the only such system operating today that has the degree of precision to handle stones as small as 0.50 mm (500 microns - hence the name) to 3.80 mm in diameter at an unmatched speed of 700 stones per hour. Simply place the batch - several thousand diamonds - in the hopper, enter the analysis data (weight, diamond reference number, etc.), and on the touch screen click on "START". The analysis cycle starts with an automated internal calibration - less than one minute - on a reference diamond included in the instrument. All analysis results are stored and retrievable at any time. Analysis is optimized by our extremely fast BE66 robot with a positioning accuracy of 5 microns. It automatically counts and places all analysed stones in one of the bins: "natural,"refer", "imitation" or "unanalysed". Developed in collaboration with the Swiss Gemological Institute - SSEF, the ASDI-500 is manufactured and commercialized by UNIMEC SA. BASEL, SWITZERLAND – OCTOBER 24, 2022: The Swiss Gemmological Institute SSEF and UNIMEC SA, a robotics company also headquartered in Switzerland, have announced the release of the ASDI-500, a new version of the Automated Diamond Spectral Inspection device.
