Absorptive Neutral Density Filters (NDA)

  • Neutral glasses
  • Densities from 0.04 to 5.00
  • Optical Density = log (1 / T)

Neutral density glasses are a convenient way of introducing attenuation into an optical system. They absorb part of the incident radiation permitting only a fraction to be transmitted. A filter set of a different OD’s of the same size is also available. Each filter will be provided a transmission scan at 546nm.
