UV Fluoresence Spectroscopy – Gemology

UV Fluorescence Spectroscopy Kit for Gemology – Complete Luminescence System by Thunder Optics

Discover one of the most effective and accessible spectroscopy solutions for fluorescence analysis in gemology. This complete UV fluorescence kit is designed to reveal the luminescent properties of precious and semi-precious stones, using targeted 370 nm UV excitation for optimal contrast and accurate identification.

What’s Included in the Kit:

Choose between two spectrometer configurations:

• ✅ O Spectrometer — a high-end, research-grade instrument equipped with a Hamamatsu S11639 linear CCD detector, delivering exceptional sensitivity and resolution, ideal for advanced gemological analysis.

• ✅ M Spectrometer — an entry-level, affordable alternative, built on the Sony IMX detector, offering good sensitivity and reliable performance for most standard fluorescence applications in gemology.

Also included:

• ✅ UV Light Source (370 nm) — available in fixed or variable power versions

• ✅ Bifurcated Y Optical Fiber Probe — for simultaneous excitation and signal collection

• ✅ M Stand (optional) — for precise and stable alignment of your spectrometer and sample

➡️ Each component is also available for purchase separately. Visit their individual product pages for full specifications, pricing, and availability.

Ideal for Fluorescence Analysis of:

• Natural and synthetic gemstones

• Luminescent stones such as diamond, ruby, spinel, fluorite, opal, and more

• Identification of trace activators (e.g. chromium, rare earth elements, organic dyes)
