Neutral Density (ND) Filters

Edmund Optics offers a wide selection of neutral density (ND) filters designed to reduce light intensity while maintaining the spectral integrity of the transmitted light. Available in absorptive and reflective designs, these ND filters support applications such as optical and imaging setups, Spectroscopy, and laser systems. With optical densities ranging from 0.04 to ≥5.0, these filters provide accurate, repeatable attenuation across the UV, VIS, and NIR spectral ranges.

Our offering also includes continuously variable ND filters, which enable smooth attenuation adjustments without swapping optics—ideal for dynamic light control in lab and industrial environments. Whether you're optimizing a fluorescence setup or integrating them into a laser-based system, Edmund Optics provides precision-engineered ND filter solutions built for performance and reliability.
