There are countless methods to analyze Materials. One method is to use photons. The start-up ‚Photonic Insights‘ provides sensors which are able to characterize a material without laboratory preparation.

“With low-resolution spectroscopy, it is not possible to get the exact waveform that corresponds to what materials are. Instead, it is an approximation. This spectrographic reading correlates to a value, therefore it does not mean it is the exact value. That difference is important for researchers, but for practical applications, it is not. A fingerprint is a representation that points to an actual value.

The sensors are able to characterise a material without laboratory preparation. If I need to tell you what is in the cup of tea you are having, I can send it to a lab. After that, you would know exactly what was in there, but it would cost a lot of money, and the sample would be destroyed. With spectroscopy, we are able to scan and take a reading. We illuminate the sample. The sample remains intact, and I can tell you various characteristics of it: the chemical composition, how much water is in there, how much caffeine is in the tea, I can even fingerprint it.“ Mike Richardson, Photonics Insights
