  • Applied Photonics, Jenoptik Make Glass-Cutting Partnership Deal
Nov 2005
SCOTTSDALE, Ariz., and JENA, Germany, Nov. 21 -- Laser-based solutions providers Applied Photonics Inc. of Scottsdale and Jena-based Jenoptik AG GmbH are combining resources to advance laser technology applications for cell phone manufacturers and for cutting flat-panel display glass in an effort to bring the new technology into the marketplace faster.

Applied Photonics has developed a patented method for making full laser cuts in attached or "laminated" display glass of 0.4- to 0.7-mm thickness with a laser, while Jenoptik is contributing its laser machines and laser systems engineering and manufacturing skills in the flat-panel display industry. Under the agreement, they will translate the new laser technology of cutting display glass to production hardware to meet display industry cleanroom production requirements. Both companies say they intend to distribute their products worldwide, with a special focus on the Asian market.

According to the companies, the optical and electronic characteristics of glass for flat displays make the material a particular challenge for processing with lasers due to the complex interaction of glass and laser energy. In comparison with conventional methods, such as scribing and mechanical breaking, cutting with lasers is faster, cleaner and more cost-effective, because the full cut also produces edges without microcracks, making the panels stronger and eliminating the need to grind the edges after cutting. As industry trends continue toward larger and thinner displays, this laser cutting technology should become an essential tool for producing high quality displays, the companies say.

A pilot system for tests and technology development has been installed at Applied Photonics and the first production system for customer applications is being set up in the Jenoptik cleanroom.

The process of forming a lens to a given pattern, or of cutting a piece of glass along the line of scratch.
A noncrystalline, inorganic mixture of various metallic oxides fused by heating with glassifiers such as silica, or boric or phosphoric oxides. Common window or bottle glass is a mixture of soda, lime and sand, melted and cast, rolled or blown to shape. Most glasses are transparent in the visible spectrum and up to about 2.5 µm in the infrared, but some are opaque such as natural obsidian; these are, nevertheless, useful as mirror blanks. Traces of some elements such as cobalt, copper and...
