ROCHESTER, N.Y., July 23, 2007 – Semrock, Inc., the leading manufacturer of high-performance optical filters for the Biotech and Analytical Instrumentation markets, today announced the extension of its renowned BrightLine series of hard-coated fluorescence filters to include the near-infrared digital imaging of biological samples. Semrock’s latest “no burn-out” fluorescence filter sets offer superb brightness and excellent signal-to-noise ratio performance for the near-IR fluorophores Cy5.5 and Cy7, and are equally well optimized for Alexa Fluor® 680 and 750.

Near-IR fluorescence imaging is rapidly increasing in popularity due to the deeper tissue penetration possible in this wavelength range, thus enabling imaging of thicker tissue samples for applications like small-animal imaging. Although tissue scattering inherently results in lower detected light levels, Semrock’s new near-IR filters sets, made as always with its advanced Ion Beam Sputtering technology, are optimized exclusively for use with digital cameras. As a result these new low-loss near-IR fluorescence filter sets offer the highest signal-to-background performance, immediately making them the filters of choice for critical near-IR fluorescence imaging applications.

BrightLine filter sets, available with certified sub-pixel image registration, ship rapidly from Semrock’s extensive stock in sizes that fit all major fluorescence microscopes. All BrightLine filter sets are hard-coated for proven “no burn-out” performance.

BrightLine filters are covered by U.S. patents issued and pending.
