Metallic Neutral Density Filters UV-VIS-NIR
Metallic Neutral Density Filters UV-VIS-NIR
Metallic Neutral Density (ND) filters from Andover Corporation provide precise light attenuation with exceptional spectral neutrality across ultraviolet, visible, and near-infrared wavelengths. These high-quality filters employ a combination of absorption and reflection through a metal alloy coating on carefully selected substrates to reduce light intensity while maintaining spectral balance.
Unlike absorption-type filters, Andover's metallic ND filters offer greater linearity over an extended spectral range (250-2000nm), making them ideal for applications requiring consistent performance from UV through NIR. Available in a range of optical densities from 0.1 to 4.0, these filters deliver superior durability and reduced thermal effects, making them excellent for calibration, scientific measurements, low-power laser applications, and imaging systems. Custom configurations are available on both fused silica and glass substrates to meet specialized requirements across various optical wavelength regions.
