Neutral Density Filters

Coating Description:

The purpose of the neutral density (ND) coating is to attenuate the incident flux. In its simplest form, the thickness of a single metallic layer is adjusted so that a prescribed transmittance is attained.

Optical Performance:

The transmission is dependent on the wavelength region. This graph shows the transmission of 2 different metallic neutral density filter coatings over visible wavelengths.

Durability Performance:

The transmission is dependent on the wavelength region. This graph shows the transmission of 2 different metallic neutral density filter coatings over visible wavelengths.
