Semrock EdgeBasic Long/Short Wave Pass Filters

EdgeBasic long-wave-pass and short-wave-pass filters from Semrock offer a superb combination of performance and value for applications in Raman spectroscopy and fluorescence imaging and measurements.

EdgeBasic filters are ideal for specific Raman applications that do not require measuring the smallest possible Raman shifts, yet still demand exceptional laser-line blocking and high transmission over a range of Raman lines.

• Deep laser-line blocking - for maximum laser rejection (OD > 6)

• Extended short-wavelength blocking - for high-fidelity fluorescence imaging

• High signal transmission - to detect the weakest signals (>98% typical)

• Proven "no burn out" durability - for lasting and reliable performance

• For the ultimate performance upgrade to state-of-the-art RazorEdge Raman filters

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 optimise the most demanding optical systems.
