JDSU Introduces New Ultraviolet Filter

MILPITAS, CA--(Marketwire - January 26, 2009) - JDSU (NASDAQ: JDSU) (TSX: JDU) today announced at the SPIE Photonics West availability of a new ultraviolet (UV) filter, an optical component critical to instrument makers and used for applications such as environmental monitoring, genetic research, biomedical instrumentation, and medical/aesthetic laser instrumentation.

The new JDSU UV filter allows for a transmission level that is up to four times higher than any other UV filter available today. It is also more durable and environmentally stable than current solutions because it is made up of hard dielectric material and has a single substrate structure.

"JDSU decided to enter the UV filter market because it is an underserved area that can benefit from our years of expertise in optical technology," said Markus Bilger, Custom Optics product line manager for the Advanced Optical Technologies business segment at JDSU. "JDSU has developed a better UV filter that will help serve the needs of researchers in many areas including environmental sciences and those working on future treatments to fight against Alzheimer's, cancer, and diabetes."

UV filters receive a broad band of light and filter it into a narrower portion of the wavelength spectrum for use in many applications. Genetic research of a cell can require an instrument that incorporates fluorescence filters to remove harmful UV rays from a light source, while allowing the correct wavelength to affect the cell in order to obtain key information.

UV filters are also used for a multitude of applications in environmental monitoring. One example includes using a UV filter to select specific wavelengths that are useful in determining whether substances such as water or oil have been contaminated with other materials.

Medical/aesthetic laser instruments employ UV light to heal skin diseases such as psoriasis or to treat caries (decayed bone or tooth), while removing the harmful portion of the UV light spectrum with a UV filter.

JDSU UV Filter at SPIE Photonics West

JDSU UV filters are available now and will be displayed at booth #1527 during the 2009 SPIE Photonics West exhibition from January 27 - 29, 2009 at the San Jose Convention Center in San Jose, CA. In addition, Dr. Georg Ockenfuss of JDSU will be conducting a presentation titled "High Performance UV Filters" on Tuesday, Jan. 27, at 12:30 P.M., in Hall 3, Demo Area 2 at the San Jose Convention Center.
