Product Family Description

  • High Transmission for Detecting Weak Signals
  • Deep Blocking for Maximum Laser Rejection
  • Ideal for Raman Spectroscopy or Life Science Instrumentation 

TECHSPEC® Raman Longpass Edge Filters are single filter solutions for reducing spectral noise in Stokes shift applications. These filters are designed to create sharp transitions between transmitted Raman signals and blocked laser wavelengths. Designed to detect even the smallest Raman shifts, TECHSPEC Raman Longpass Edge Filters are ideal for integration into Raman spectroscopy or confocal microscopy systems. The hard coated design offers superior transmission characteristics than comparable traditional coated filters.
