Ni090 Neutral Density Filter

Description

Ni090 Neutral Density Filter

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 : 400-1100nm
• Optical Density : 0.9
• Transmission: 12.50%
• Tolerance : +/- 1.50%
• Surface Quality : 40/20

Ni Series – Broad Spectrum; VIS/NIR

• Low reflectivity filter effective from 400-1100nm
• Available in optical densities ranging from 0.3-1.2
• Coated on low-expansion, heat-resistant Borofloat glass

Neutral Density Filters serve as “sunglasses” for your system and can be used with monochrome or color cameras. Designed to reduce light intensity neutrally over a specific wavelength range without affecting image color or contrast.

• Available in a variety of optical densities
• Reduce light intensity while maintaining a wide aperture and shallow depth of field
• Minimize pixel saturation
• Can be stacked with other Neutral Density Filters to test various optical densities
• Exceptional surface quality; 40/20 scratch/dig

Ni060 Neutral Density Filter Applications

Applications include imaging in intense lighting situations (i.e. molten metal and welding) outdoor aerial imaging and photography. Neutral Density Filters help reduce shutter speed to create blur, preventing a “jello” effect in aerial imaging.

Mount & Size Options

In-stock, ready-to-ship Neutral Density Filters are available in Threaded Mounts, sizes M13.25 to M105; 25.4 C-Mount; Slip Mounts; or Unmounted. Custom shapes and sizes are available.
