Gem UV-100 is based on the principle of spectral measurement, and uses the spectral absorption characteristics of different gemstone materials in the ultraviolet visible near-infrared band to quickly and non destructively detect the species, genesis, and optimized processing characteristics of gemstones. Integrated design of the whole machine, built-in high-performance embedded host and high-definition capacitive touch screen; Integral sphere and external fiber optic probe dual optical path one key cutting meet the testing needs of samples in different scenarios, shapes, and sizes.

Performance characteristics

New generation FFT-CCD detector
Adopting the FFT-CCD surface array detector from Hamamatsu Corporation and TEC cooling (up to -15 ℃), the detector has lower noise and is more conducive to low light detection; By processing the pixel points of the area array CCD, the sensitivity and signal-to-noise ratio (>1000:1) are greatly improved, and the processing speed is also increased.

Full signal balanced light source
To compensate for and improve the trough in the light source curve between ultraviolet and visible light, a customized dichroic filter is used to superimpose ultraviolet and visible light, thereby achieving light source balance; In order to match the peak shape of ultraviolet light sources, the intensity of visible light sources is adjustable.

Integral sphere and reflective measurement
The instrument supports two measurement methods: integrating sphere and reflective (external reflective fiber), which can be freely switched through an electric switch; Most samples can be measured using an integrating sphere. For particularly large samples or dense small particle samples, using a reflective fiber optic probe for measurement is more convenient.

Liquid nitrogen sample pool (optional)
Optional liquid nitrogen sample tank; Low temperature conditions can effectively reduce the thermal vibration of sample molecules, allowing for clear reproduction of weak absorption peaks that cannot be measured at room temperature; Especially due to the absorption peak caused by crystal lattice vacancies, the absorption intensity will increase by orders of magnitude; The 41nm absorption peak of irradiated diamonds.

Comprehensive rapid detection software system
Comprehensive fast detection software, supporting free switching between fast detection and scientific research modes with external screens or hosts
The software supports multi-channel measurement and multi terminal control; Customizable measurement modes, such as diamond phosphorescence testing
CIE chromaticity measurement: standard chromaticity measurement function, used for measuring and grading gemstone colors, supporting data group export/import
Database: Built in common gemstone standard library, supports custom library and automatic retrieval matching; The historical database supports data group storage, import/export, facilitating daily data management and accumulation, and can be imported into the standard library; Cloud database support, real-time updates
