Neutral Density (ND) Filters
Neutral Density (ND) filters are precision optical components engineered to provide controlled light attenuation while maintaining spectral distribution integrity across specified wavelength ranges. These sophisticated optical elements act as precise light controllers, reducing intensity uniformly without altering the spectral characteristics of the transmitted light - a critical capability for applications from advanced imaging to laser systems.
Andover Corporation manufactures Neutral Density filters using multiple advanced construction technologies, including metallic coatings, absorptive materials, and specialized IR solutions. Our comprehensive portfolio spans optical densities from 0.1 to 4.0, with exceptional spectral neutrality from UV through IR wavelengths. Whether you need premium image-quality filters with minimal back-reflections, broad-spectrum metallic filters with superior durability, or specialized IR solutions, our vertically integrated facility ensures consistent quality and reliable delivery for both custom projects and high-volume production runs.
