Daheng New Epoch Technology, Inc. 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
Circularly variable neutral density filters are designed to simplify attenuation and beam splitting from VIS to near IR. The optical density gradually varies around a 270 circle for convenient attenuation...
The metallic coatings on one side of the filter provide a nearly constant amount of transmitted energy over a wide visible and near infrared waveband. CDHC's neutral density filters are...
This ND filters provides linearly varying attenuation or beam splitting in the visible and near infrared region. The optical density varies linearly across the length. Attenuation is achieved by a...
