From Optical Excitation to Automated Identification
Understand how physical light excites atomic crystal defect centers, disperses into calibrated nanometer channels across a high-resolution spectrometer, and transforms through intelligent algorithms into definitive PASS / NOT PASS screening results.
From Light to Insight
A continuous scientific progression connecting physical optical excitation to definitive screening decisions. Every stage from initial photon delivery to algorithmic interpretation is engineered for absolute repeatability.
Stabilized Optical Excitation
A calibrated optical excitation source delivers stabilized electromagnetic radiation to the stone inside a shielded measurement chamber. Mindron systems employ broadband continuous UV-Vis-NIR light (200 nm – 1100 nm) alongside narrow-band laser wavelengths (405 nm and 532 nm) designed to stimulate absorption, transmission, and photoluminescence without thermal or structural risk to the specimen.
Stabilized photon flux illuminates the diamond table or gemstone facet under shielded chamber optics.
From Spectral Data to Intelligent Identification
Mindron Spectrum systems combine optical measurements with computational models to process complex datasets, compare patterns, and assist with material classification. The analysis is performed automatically, allowing users to receive a simple result such as PASS / NOT PASS without needing to interpret complex spectral data manually.
SPECIMEN ACQUISITION
Loose stone or mounted jewelry placed into shielded optical chamber; sub-second photon integration triggered.
SENSOR INTEGRATION
2048-pixel linear CCD array digitizes spectral response across calibrated 200–850 nm channels.
SIGNAL CALIBRATION & DSP
Real-time thermal dark-current subtraction and 4th-order polynomial baseline deconvolution.
FEATURE DECONVOLUTION
Algorithmic extraction of zero-phonon defect peaks (N3 @ 415.2 nm, SiV @ 737.0 nm, Raman @ 1332 cm⁻¹).
INSTANT VERDICT GENERATION
Automated correlation against Mindron reference library produces clear PASS / NOT PASS determination.
Every Spectrum Reveals the Atomic Lattice
Zero-phonon defect lines, absorption bands, and lattice phonon vibrations create definitive optical fingerprints that differentiate natural subterranean gems from lab-grown synthetics, simulants, and treated stones.
Fundamental optical marker in natural diamond screening. Absent in pure Type IIa, CVD, and HPHT synthetics.
