Frank Korte and Günter Kamlage of Micreon GmbH created this 2 milimeter-wide glasses using laser. From the press release:
Micreon GmbH, the latest spin-off company of the LZH, focuses on micro processing using state-of-the-art laser technology. The company is the first to use ultra short pulse lasers for the manufacture of highly-precise components. Any material can be processed by ultra short pulse lasers without any damage, and, in addition, precisions of less than one thousandth millimetre can be achieved.
To illustrate the great opportunities of laser precision processing, the Micreon team have manufactured a glasses frame for a housefly. It may well go unnoticed by the layman, but the funny example of a housefly wearing designer glasses demonstrates the large potential of micro system technology for high-tech products.
