Laser-Based Process delivers oven-less annealing.

Press Release Summary:

Oven-less process, used for annealing glass coatings, involves laser beam swept over surface to anneal coating applied to glass. Heat Affected Zone (HAZ) is limited, and material can be handled relatively soon after annealing is complete. Process promotes light transmission efficiency while reducing electrical surface resistance and preventing delamination. It also performs recrystalization of glass.

Laser Photonics Develops New Oven-less Annealing Process

Lake Mary, FL., January 9, 2009 - Laser Photonics, the industry leader in developing high-tech solid state and CO2 laser systems for marking, cutting and engraving applications, announced today the development of a new laser based oven-less process for annealing glass coatings.

Traditionally, to anneal a coating on glass, the coating was applied to the glass, baked at 600 degrees Celsius, and then cooled for three to four hours. Using this new oven-less annealing process developed by Laser Photonics, the coating is applied to the glass and then a laser beam is swept over the surface to anneal. The Heat Affected Zone (HAZ) is limited and the material can be handled relatively soon after the annealing is complete. Using this new process, the light transmission efficiency is increased by 35%. Additionally, the process lowers the electrical surface resistance, prevents de-lamination and performs recrystalization of the glass. Glass that has been coated and annealed is used for such things as: architectural glass, as seen in large buildings and skyscrapers, windshields and solar panels.
