A new laser technology has been developed by the Belgian company Trackinside; one that can inscribe glass without heating, cracking or leaving any unwanted marks. Jean Michel Mestrez, Managing Director of the company, stated that it is “the only technology that can mark glass without damaging it.”
The device was originally created for etching the surfaces of mirrors and lenses, with hopes to improve telescopes and other measuring equipment, but the technology also has many other uses. With it, you can mark syringes and medication capsules as they are manufactured, as well as keep track of them. It can also be used as a protection against counterfeiting.
The ‘femtosecond laser’ functions in a similar way to those used in eye surgery. It directs energy through the surface of the eye in order to make incisions far beneath it.
