Corning Intros Wideband Polarizer

CORNING, N.Y. -- Corning Incorporated (NYSE:GLW), an industry leader in glass polarizers for telecommunications applications, today announced the launch of Polarcor(TM) W I D E band(TM), a solid glass polarizer with high performance in both the 1310 and 1550nm wavelengths. This unique polarizer, a keystone component in polarization-dependent optical isolators, allows customers to minimize inventory complexity and costs by maintaining only one product for the two operating wavelengths.

The silver-based polarizer, manufactured using a patented process, absorbs unwanted light to create a linearly polarized light with high extinction ratio and transmission. Since Polarcor is a solid glass product it is extremely resistant to chemical, physical, and thermal damage while exhibiting excellent optical properties. Polarcor W I D E band polarizing glass maintains superior performance from 1275 to 1635 nanometers. Products with an antireflection coating have a contrast ratio exceeding 50dB, transmittance greater than 98% and reflectance less than 0.2%.

"Polarcor W I D E band polarizing glass compliments Corning's other polarizer product offerings which include standard Polarcor(TM) and Polarcor(TM) UltraThin(TM) polarizing glass products," stated Tara Dowdell, Corning Polarcor product line manager. "Polarcor W I D E band polarizing glass is the first of its kind in the industry and offers customers a significant advantage with regard to inventory management and reduced cost and complexity. We remain committed to the continued improvement, expansion and protection of the Polarcor product line, as it has served our customers reliably for over two decades."
