Optical spectroscopy has the capability to rapidly, objectively, and non-invasively identify material at molecular level. However, spectrometers are often bulky and costly, severely limiting the number and form of applications they can be used for.  With its mini-spectroscopy technology that was designed to support smart, healthy and secure living, ASTRI overcomes those obstacles.

Jewellery businesses, in particular, find it a handy consumer-grade tool. The spectrometer’s size and low cost make it accessible to almost anyone, anywhere, and that’s why it’s used widely to analyse the authenticity of gems.

The spectrometer’s recognition function allows a person to determine whether a diamond is natural or synthetic; whether jade is natural or has been chemically treated; whether a coloured gem is thermal treated; or even if a pearl is saltwater or freshwater in origin.

In the future, the spectrometer could even be made compatible with smartphones that have infrared capabilities, to extract colour and  chemical information from a variety of materials.

The spectrometer can be used on a wide range of daily-life applications, from monitoring the quality of oil and food products, to identifying medication, and even analyse a person's skin condition.

Patent number: US20200025611A1
Patent name: Compact spectrometer having reflective wedge structure

An example of the spectrometer’s application outside the jewellery industry is through the in-line aqueous ion monitor, which is able to constantly measure low-concentrations of ion residue in water. This technology can help save water in the washing process, as well as be useful as an automatic in-line monitoring system in hydroponic-farming. Ultimately, this technology will go a long way in supporting environmental sustainability.
