Spectrally shaped & optimized light source
The GemmoSphere™light source has been spectrally shaped with a special set of optical filters for enhancing both blue and near infrared areas of the spectrum. Additionally a series of balanced UV-sources are used for increasing the amount of UV-radiation. Finally, material with excellent UV- and blue light reflection properties has been used for manufacturing the integrating sphere.
The image on left shows the difference between the raw spectra of regular halogen source used in most similar products (yellow line) and GemmoSphere's spectrally shaped light source (green line).
As a result of this spectral shaping we are happy to offer a gemology- oriented spectrometer producing noise-free results for the whole 365 - 950 nm measurement range. The maximum noise-free absorption is about 3.0 (1/1000th of light passing trough the sample) at the UV & visible areas of the spectrum, and about 2.0 at the NIR-area.
