Equipment Name: Diamond Rapid Identification Instrument

Purpose: Based on the principle of spectral measurement, effectively targeting natural diamonds（IaType, colorless-Light yellow series) for rapid screening, can be used to synthesize diamonds（CVD、HTHP）Distinguish it from other diamond imitations; The instrument is compact and portable, suitable for testing in different places.

Equipment performance, technical requirements, and technical parameters:

1）Scope of application: Colorless or nearly colorless diamonds;

2）Detection range:0.01-10Carat, naked or set diamond;

3）Judgment basis: Measurement of diamondsN3Color center absorption spectrum;

4）Result judgment: Software intelligent discrimination; containN3Color center diamonds pass, other diamonds (synthetic diamonds and imitation diamonds) do not pass; The test results are output in both graph and speech formats, and the graph can be saved and exported;

5）Passing rate:98%above;

6）Testing time: single time100Continuous testing within milliseconds;

7）Testing method: Reflection measurement; The fiber optic probe is fixed inside and can be removed for handheld testing;

8）Integrated instrument design (with built-in sample stage, calibration module, fiber fixing device, and testing and monitoring module), no need for external equipment or accessories, compact and portable;
