Jewelry and jade detector

Model: UVN5000

Product Description, Technical Parameters, and Configuration

Product Name: Jewelry and Jade Detector, also known as UV Visible Near Infrared Spectroscopy Detector

Model: UVN5000

The UVN50000 jewelry and jade detector is a spectral analyzer based on measuring the wavelength of total reflection light waves. Its wavelength range is ultraviolet, visible light, and near-infrared, and it can effectively detect the spectral reflection characteristic curves of hundreds of types of jewelry.

Measurement object: Diamond: containing natural diamonds CVD, HTHP, Irradiation treatment, etc; Jade and stones: jadeite, etc; Colored gemstones: sapphire, ruby, turquoise, beryl, etc; Organic gemstones: gold pearls, black pearls, red corals, etc

Technical Specifications:

Detection range: 200-1100nm

Signal to noise ratio (full signal): 450:1

Single measurement time: 2us (with electronic shutter)

Resolution: 0.06-20um optional

Stray light:<0.3%

Sensitivity: 460000 counts/uW

Detector: Hamamtsu 2048 pixel two-dimensional array, 14um * 500um backlit CCD

Light source: A balanced light source optimized for full signal design, with a combination of adjustable tungsten and deuterium lamps. It has a good linear distribution in the full signal area, greatly improving the signal quality in the full spectral range, and providing more accurate and stable test results

Sample cooling: invasive, low-temperature liquid nitrogen sample pool (-196 ℃), effectively reduces the thermal vibration of sample molecules at low temperatures, allowing for clear reproduction of weak absorption peaks that cannot be measured at room temperature

Absorption curve testing and digital spectrum display: The shape of the sample does not affect the test results. After the spectrum testing is completed, in addition to displaying specific absorption peaks normally, the software also provides a special digital light source image for users to compare with the spectroscope image

Stability:>99%

Measurement sampling methods: integrating sphere and reflection

Database: Standard database and expert database, can be upgraded to cloud services (real-time updates)

Sample cavity size: 255x125x70mm

Signal interface: USB 2.0

Product size: 560 * 430 * 280mm

Product weight: 19.5kg

Power supply and output: 220V-50HZ/250W
