Stepped Neutral Density (ND) Filters

×
  • 11 Discrete Density Steps
  • Design Wavelength of 400 - 700nm
  • Density Neutrality of ±5%

Density and transmission vary in eleven equal steps across the surface length. The steps are abrupt changes and no light escapes between them. Spectrally flat neutral density coating. Ideal for applications requiring variable densities and known density values.
