Raman longpass filters help detect low-wavenumber Raman signals

ODiate Raman longpass optical filters are optimized to block 488-, 532-, 632.8-, and 785-nm laser lines.
Sept. 12, 2025

ODiate Raman longpass optical filters provide optical density blocking of Rayleigh scatter (≥ OD 6), high transmission of Stokes Raman scattering (≥ 93% Tavg), and sharp wavelength transitions (edge steepness ≤ 0.5%). This allows for the detection of low-wavenumber Raman signals. They are optimized to block 488, 532, 632.8, and 785 nm laser lines.
