Semrock Awarded U.S. Patent for Ultrasteep Edge Filters

Rochester, N.Y. – Semrock, Inc., the leading manufacturer of high-performance optical filters for the biotech and analytical instrumentation markets, announced today they have been awarded U.S. Patent No. 7,068,430 for a novel class of ultrasteep thin-film based optical edge filters. This patent offers formal protection for the company's popular RazorEdge® series of Raman Filters. RazorEdge ultrasteep edge filters, available in both long-wave-pass and short-wave-pass versions, are widely used to measure small Raman shifts, while offering deep laser-line blocking for maximum laser rejection, and high signal transmission to detect the weakest signals.

"By combining its innovative advances in the pinnacle Ion Beam Sputtering deposition process, with unique optical designs that precisely addressed an important problem in spectroscopy, Semrock introduced state-of-the-art optical edge filters that quickly became popular with both OEM's and end-users," said Dr. Turan Erdogan, CTO of Semrock. "This patent, which reinforces the novelty of our approach to achieving unprecedented levels of performance and reliability in Raman filters, joins a growing body of Semrock patents for its innovative filter products."
