Andover Corporation manufactures metal coatings and absorptive ND filters.
■Metallic ND Filter - Optical density is achieved by depositing a metal alloy onto a substrate selected for the desired wavelength range. ■Absorptive ND Filter - Manufactured using Schott NG glass, it strictly relies on the absorption effect of the glass to achieve the desired attenuation level. *These ND filters are also available for sale as a set. *All sets come with a storage wooden box.
