Semrock® Extends High Performance UV Filter Line

Ion Beam Sputtered filters now available for 224 nm laser

ROCHESTER, N.Y., July 20, 2007 - Semrock, Inc., the leading manufacturer of high-performance optical filters for the Biotech and Analytical Instrumentation markets, today announced the extension of its family of high performance high-reliability UV filters, including now a unique long-wave-pass Raman spectroscopy filter for use with state-of-the-art 224.3 nm HeAg hollow-cathode metal-ion lasers.

Other new UV filters include additional long-wave-pass and laser-line filters - all with unparalleled performance and proven reliability. Semrock's popular RazorEdge® family of ultrasteep long-wave-pass Raman spectroscopy filters now extends from 224 nm to 1064 nm. Semrock's complementary family of high transmission MaxLine® laser-line filters now spans the range from 248.6 nm to 1064 nm. The performance and breadth of these offerings leads the industry, and all are available from stock.

"When Semrock unveiled its first high performance UV filters in January there was a great deal of excitement, leading us to quickly expand the UV offerings", says Dr, Turan Erdogan, CTO of Semrock. "We are very excited about our latest demonstrated ability to offer Ion Beam Sputtered filters with useful features to below 230 nm. And these cutting edge UV filters are so manufacturable with Semrock's proprietary processes that we have added them to our new 2007/2008 print catalog."

RazorEdge and MaxLine filters are covered by U.S. patents issued and pending.
