ESA's Heart of Glass: Trackinside

What’s the best way to keep track of medicines or luxury goods? Just give them a number, of course. But what if the item you want to keep your eye on is made of glass?

Thanks to a new laser technology developed for space, a Belgian start-up company called Trackinside is now able to inscribe numbers in glass without cracking, heating or leaving any external marks on the glass.

“It’s the only technology that can mark glass without damaging it,” said Jean Michel Mestrez, Trackinside Managing Director.

The low-impact laser inscribes serial numbers inside, rather than on the surface, of the glass used in medical syringes, perfume vials or drinks bottles.

The laser technology was initially developed in Belgium at the Centre Spatial de Liège (CSL), working with the LASEA CSL-spinoff group, which was initially devoted to developing cleaning processes using lasers.

CSL is a partner of the Belgian Space Technology Platform, ESA’s national technology transfer broker.

There, it was created for things like etching the surfaces of lenses and mirrors that would then be used in space telescopes and measuring equipment.

The ‘femtosecond laser’ works much like the laser used in eye surgery, where it beams energy through the surface of the eye to make incisions deep below.
