16 September 2003 Farum, Denmark -- Ibsen Photonics has relocated the manufacturing of its holographic phase masks to the company's new 1,300 m2 (approx. 14.000 sq.ft.) cleanroom facility in Farum.

Kristian Buchwald, Ibsen's product manager, said, "We have always produced our phase masks in our own clean room - which was class 100 - but now we have reduced defect counts in the masks since relocating manufacturing to our new class 10 clean room."

Phase masks are strategic tools in the manufacture of fibre Bragg gratings and integrated optical components. Cleanliness of the mask is important, as the mask is used as a master and a reduction in defects gives improved and more homogeneous visibility of the fringe pattern generated in the fibre core.

"In the three month run-in period at the new facility we have seen an improvement of more than 50% in the cleanliness of our masks using our defect inspection systems," says Buchwald.

"We have always focused on characterisation of our phase masks and have also used our defect inspection systems to monitor and improve our individual processes, so that we can now offer improved cleanliness specifications"

Ibsen Photonics is leveraging more than 10 years experience in diffractive optics to market its phase masks that increase manufacturability of optical components. The company is also focusing on DWDM modules based on the Ibsen Diffractor technology that increases flexibility and improve operational costs of telecommunication DWDM networks.

Furthermore the company is pursuing partnerships in other industries to expand its diffractor platform based on Ibsen's pure fused silica holographic diffraction gratings.
