Newport Corporation Datasheets for Neutral Density Filters

Neutral density filters are designed to reduce transmission evenly across a portion of the spectrum. They are slightly sensitive to angles but they are much more forgiving than interference filters.

Product Name Notes
Infrared Neutral Density Filters Made from Germanium material, these filters attenuate IR radiation from 2 to 14 µm. The one-inch diameter filters are coated with a spectrally neutral vacuum deposited metal alloy reflective coating.
Glass Neutral Density Filters and Kits Made with Inconel® metallic coatings on glass substrates, these moderately priced ND filters provide uniform attenuation of low and medium power beams across a broad spectral range. Economy neutral density...
Absorptive Neutral Density Filters Newport's absoprtive ND fitlers are precision polished, and offer uniform attenuation over lower power beams across the visible range at an economical price suitable for OEM integration. Low cost ND...
Optical Crown Glass Metallic Neutral Density Filters Our metallic neutral density coatings provide broadband attenuation for low power applications. The coating is deposited on one side of a cost effective B 270 optical glass substrate, providing excellent...
UV Fused Silica Metallic Neutral Density Filters Our metallic neutral density coatings provide broadband attenuation for lower power applications. The precision polished UV fused silica substrate, the filters may be used anywhere from 350 to 2000 nm.
Circular Variable Metallic Neutral Density Filters The circular variable ND filters allow users to finely tune the power of a transmitted beam, or to split a beam with an arbitrary power ratio easily by simply rotating...
Circular Linear Variable ND Filters The circular variable ND filters allow users to precisely attenuate or split the power of a transmitted beam by an arbitrary ratio. The density of this filter varies linearly with...
