Metallic Neutral Density Filters VIS-NIR
Metallic Neutral Density Filters VIS-NIR
Metallic Neutral Density (ND) filters from Andover Corporation provide precise and cost-effective light attenuation across the visible and near-infrared spectral range (400–2000 nm). These filters utilize durable metal alloy coatings deposited on carefully selected green glass substrates.
Optimized for VIS-NIR applications where UV transmission is not required, green glass substrates provide reliable optical performance and excellent spectral neutrality across the visible and near-infrared regions.
