Every Semrock filter is hard-coated for durable performance. Ten year warranty
Semrock stocks an unsurpassed selection of the highest performance edge filters available for Raman-spectroscopy, with edge wavelengths from 224nm to 1319nm. Now you can see the weakest signals closer to the laser line, than you ever have before. With their deep laser-line blocking, ultra-wide and low-ripple passbands, proven hard-coating reliability, and high laser damage threshold, they offer performance that lasts. Razor Edge filter technology is unique and patented.
Steepest edges to measure even the smallest Raman shifts
Deep laser-line blocking for maximum laser rejection (> OD6)
High signal transmission to detect the weakest signals (>98% typical)
High laser damage threshold and proven reliability (1 J/cm2 for 532nm)
Rejected light is reflected for convenient alignment and best stray-light control
UV long-wave-pass filters for wavelengths as short as 224nm
As the industry’s best for high-performance optical filters, Semrock products from IDEX Health & Science deliver the stability required for life science, analytical, and medical diagnostic instrumentation. By utilising proprietary hard-sputtered coatings, our filters eliminate environmental degradation and drift—a level of reliability backed by our 10-year warranty. We ensure faster measurements and minimal downtime by prioritising steep edges and deep blocking to maximise your signal-to-noise ratios. From standard components to custom solutions, Semrock filters provide the superior stability and spectral precision necessary to optimize the most demanding optical systems.
