Stories & Features
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.
IDEX Health and Science understands these challenges, and we are proud to announce our latest Semrock-brand optical filters 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:
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.
Verona’s low ripple provides the best signal-to-noise ratio, allowing for maximal collection of weak Raman spectral features.
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 both low ripple and improved steepness from our RazorEdge™ series, making the Verona family the new gold standard for Raman analysis. Push the limits of what you can see with your Raman system with Verona Raman filters.
