Increase Raman System Performance with the new Verona™ Filters Series from Semrock!

Raman spectroscopy and microscopy are powerful, non-destructive analysis techniques that require the ability to resolve signals from weak, inelastically scattered light spectrally adjacent to the laser line. These measurements generally face two limitations:

• Raman scattering cross sections are tiny, requiring intense lasers and sensitive detection systems just to achieve enough signal.
• The signal-to-noise ratio is further limited by fundamental, intrinsic noise sources like sample autofluorescence.

The new Verona™ optical filters product line from IDEX Health & Science / Semrock has been specifically designed for Raman instruments and provides the following benefits:

• Transition width (cut-off) ≤ 0.2% allowing for maximal unobstructed signal collection two times the actual Semrock RazorEdge® E Grade filters
• Steepness improved from Semrock's RazorEdge® series
• Low ripple to provide the best signal-to-noise ratio and allow for maximal collection of weak Raman spectral features
• Deep blocking of > OD 6 at the laser line that eliminates bleed-through of excitation light
• Hard coated for high laser damage threshold to prevent performance degradation
• Availability in 12.5mm housed standard sized parts and 10mm clear aperture, providing more real estate for your most demanding applications
• Verona’s improved transition width enables you to collect more Raman signal closer to the laser line for higher resolution images and spectra.
