The Inspectrum provides a convenient and portable way to perform optical spectroscopy on gems. It illuminates a gem under evaluation with white light and then analysing which wavelengths have been transmitted or absorbed after interacting with the gem.
The instrument comprises a visible light spectrometer combined with a 405 nm laser and white light source. It provides both fluorescence and transmission spectra from gems.
The Inspectrum has been specifically designed for use with facetted diamonds, especially for the detection of lab-grown and treated diamonds. It is unique in several respects:
A PC is required to interface with the spectrometer and to be able to save spectra as txt files and be able to compare with some reference spectra.
Examples of a PL and transmission spectrum are shown opposite.
