Edge Blackening
Improved 2023 Capabilities
Protect your system from stray light with our new and existing Edge Blackening capabilities for optical filters.
Nanopede™ Filters
Designed for Essential Performance
Filters covering visible spectrum 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.
SearchLight™
Transform the Way You Design
Make decisions faster and eliminate wasted development time with our free spectral viewer and analysis tool: SearchLight.
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.
If you are a North American laboratory, university, or government agency, please consider placing your order directly with our distribution partner, AVR Optics. Visit AVR Optics
