Description
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 optical densities.
- Useful Range: 400 to 2000 nm
- Optical Density: 0.9
- Transmission: 12.50%
- Tolerance: +/- 1.50%
