We're the same Semrock Optical Filters you've known for years, now with an upgraded website to give you a better experience. Click to learn more.
Designed for Essential Performance
Filters covering visible spectrum (UV and NIR coming soon) in discrete steps, enabling the balance of instrument cost and optical filter performance.
Avant™ Filter Set Family
Maximize Fluorescence Performance
Avant delivers significant increases in fluorescence signal for specific, popular short Stokes Shift fluorophores.
Spectral Measurement System
KolaDeep measures the steepest and deepest spectral features so your instruments can reach best-in-class using the latest high-performance Semrock filters.
Enhance Raman System Performance
Push the Limits of What You Can See
with Verona™ Filters: designed from the ground up specifically for Raman instruments.
Enhanced Product Filtering
Optical filters can be searched by individual filters and by set. You will also still have access to the e-store left navigation filtering that you are used to from the historic semrock.com to search by wavelength, filter families, fluorophore, filter type, light source, laser wavelength, edge steepness, flatness, application, and more.
Select your bandpass, edge filters, dichroics, and more by key fluorophores.
Optical Filter Sets
Explore single-band and multi-band sets for popular applications and wavelengths.
