Increase Raman System Performance with Semrock Verona Filters
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: (1) Raman scattering cross sections are tiny, requiring intense lasers and sensitive detection systems just to achieve enough signal; and (2) the signal-to-noise ratio is further limited by fundamental, intrinsic noise sources like sample autofluorescence.
Laser 2000 understands these challenges, and is proud to offer Semrock’s latest optical filters, which are designed from the ground up specifically for Raman instruments. The new Verona™ optical filters product line has been designed with your needs in mind:
- With transition width (cut-off) ≤ 0.2% allowing for maximal unobstructed signal collection two times our actual Semrock RazorEdge E Grade filters
- Steepness improved from our 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
- With our award-winning, proprietary Kola Deep spectral measurement system, we provide the spectral data to prove our superior deep blocking and edge-steepness performance
- Availability in 12.5mm housed standard sized parts and 10mm clear aperture, providing more real estate for your most demanding applications
Improved transition width, ultra-low ripple
Verona’s improved transition width enables you to collect more Raman signal closer to the laser line for higher resolution images and spectra. We offer the best transition on the market, backed by the Kola Deep™ Spectral Measurement System.
Push the limits of Raman with Semrock Verona filters
Semrock’s long-pass Verona™ optical filters provide industry-best solutions for deep blocking close to the laser line for Raman applications. Verona is just the beginning of our evolving Raman product line to match the rapidly developing Raman market. Our understanding of how crucial flat transmission is for the maximal collection of weak Raman signals is why we offer a filter with ultra-low ripple, in addition to the steepest edges, making the Verona family the new gold standard for Raman. Push the limits of what you can see from your Raman system with industry-best transition width.
