Neutral Density Filter Sets

Neutral Density Filter Sets
Neutral Density Filter Sets from Andover Corporation offer precision light control in convenient, comprehensive packages. These carefully curated collections provide researchers, photographers, and optical engineers with a range of optical densities in a single purchase, allowing for precise attenuation of light intensity without altering the spectral distribution.
Available in both metallic-coated and absorptive varieties, these sets come in various configurations including 7-piece, 14-piece, and 17-piece options with optical densities ranging from 0.1 to 4.0. Each set is housed in a quality hardwood case for secure storage and protection. The metallic-coated sets feature both round and square filters in multiple sizes and substrate options, while the absorptive sets are ideal for imaging applications where minimizing back-reflections is critical. With consistent spectral neutrality across their designated wavelength ranges, these filter sets are essential tools for calibration, photography, machine vision, and scientific measurement applications requiring precise light management.
