AI Technical Summary

Technical Problem

Existing gem testers have accuracy problems when detecting natural diamonds and synthetic diamonds, especially the inability to effectively distinguish natural diamonds from CVD/HPHT moissanite silicon carbide, and the deterioration of the ultraviolet light source will affect the test results.

Method used

A gem test device was designed, using a dual detection mechanism of long-wave and short-wave ultraviolet light. The UVA/UVC LED unit is combined with a quartz light guide column, and the central control unit is used to coordinate the test process to ensure the independent configuration and isolation of the ultraviolet light source and avoid deterioration. , and thermal conductivity test is performed through thermal conductivity.

Benefits of technology

Accurate distinction between natural diamonds, moissanite, CVD/HPHT diamonds and other gemstones is achieved, ensuring the stability and accuracy of the test results, avoiding early deterioration of ultraviolet light sources, and improving the reliability and economicality of the tester.

Abstract

A gem test device and method, the gem test device comprising a test circuit, a housing accommodating the test circuit, and a test probe unit extending out of the housing, the test circuit comprising a UVA / UVC module, a heating system adapted to emit UVA LED light and UVC LED light to a gem to be tested, and adapted to apply heat to the gem to be tested, a test end of a quartz light guide column is in contact with a to-be-tested gem, UVA LED light and UVC LED light penetrate through the to-be-tested gem and then are reflected, guided and focused on a UVA / UVC optical sensor, and meanwhile, a heat pipe surrounding the quartz light guide column applies heat generated by a heating system to the periphery of the to-be-tested gem; through the mechanism, the measured gemstone can be divided into diamond / cultivated diamond / moissanite / red sapphire or gemstone with thermal conductivity / cubic zirconium oxide or glass.
