B&W Tek's GemID identification software allows you to navigate your GemRam™ Raman spectrometer using user-friendly icons and instructions. You can easily choose to verify a known gemstone or identify an unknown gemstone by measuring the spectrum of the gemstone, then comparing it with that of the GemExpert library included in the software. You can also view the general spectra and results of your measurement independent of the library, or add an unlimited amount of your spectra to the library to use for future comparisons.
B&W Tek's exclusive GemID identification software, preloaded in every GemRam™, is powered by GemExpert's spectral library of nearly
400 different gemstones. The library contains gemstone spectra for all classes, including: borates, carbonates, halides, native elements, oxides, phosphates, silicates, sulfates and sulfides. Different varieties of each gemstone from around the world are also available in the GemExpert library. Each entry within the library includes the commercial name, a picture of the gemstone, the country of origin, and other information that will assist with quickly identifying and verifying gemstones.
Raman Gemstone Identification System
The GemRam™ is a lightweight, portable Raman spectrometer dedicated to both the verification of known precious and semiprecious gemstones as well as the identification of unknown gemstones. It utilizes a spectrum stabilized 785nm diode laser and a high resolution TE cooled spectrometer to provide spectral accuracy and repeatability, all within a compact system that can easily be carried between locations.
The system comes equipped with B&W Tek's proprietary GemID identification software, powered by GemExpert. The software not only includes a spectral library of nearly
400 different gemstones, but also allows unlimited space to add user defined spectra at any time.
Purchase of the GemRam™ includes an X-Y-Z positioning stage for accurate and repeatable measurements, a fiber optics probe, as well as a netbook computer, preloaded with GemID software and GemExpert's spectral library, all in a convenient and durable carrying case.
