Semrock Sets New Standard for Raman Filters


Rochester, NY - Semrock, a manufacturer of advanced optical coatings and filters, today announced the availability of a new line of Raman spectroscopy edge filters offering unprecedented performance for a wide range of industrial, analytic and research laboratory uses. These innovative thin-film filters have three times the Stokes-edge steepness of even the leading holographic filters, which have traditionally set the standard in spectral performance. The new Semrock filters combine deep blocking of the Raman laser line, tight edge-wavelength accuracy and high signal-band transmission for detecting the weakest signals over the widest spectral range. This exceptional performance is made possible by combining the latest in ion-beam sputtering thin-film technology with Semrock's unique manufacturing tools and techniques. Unlike holographic filters, the new filters have the proven environmental stability of hard dielectric oxide coatings deposited on glass.

The new Semrock standard in Raman analysis filters now makes high-performance in Raman spectroscopy more widely accessible. "For the majority of important Raman applications where only the Stokes light is collected, such as in chemical process monitoring, our Raman edge filters provide significantly higher performance than premium holographic notch filters yet for less than half the price. This constitutes a significant advance to manufacturers and researchers needing high-performing yet cost-effective filters," said Dr. Victor Mizrahi, President and Chief Executive Officer of Semrock.
