Current Stock:

Ni090 filters exhibit uniform attenuation over the entire visible and near-IR range that most industrial CCD/CMOS cameras are sensitive within. The actual percent transmission averages a nearly constant 12.5%, while reflectivity in the visible portion of the spectrum averages 30%. These filters include identical male and female threads on either end so that they can be stacked with other ND filters to achieve various optical densities.

  • Useful Range : 400-2000nm
  • Optical Density : 0.9
  • Average Transmission: 12.50%
  • Tolerance : +/- 1.50%
  • Surface Quality : 40/20
Note: Midwest Optical filters are considered to be special order items and are thus not returnable.
