Description

ND120 Neutral Density Filter

ND120 absorptive neutral density filters have an optical density of 1.2, averaging 6.25% transmission over the visible spectrum. 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. For example, the result from stacking two ND120 filters together would be very similar to utilizing one (ND240) filter. Visible transmission would approximately equal 0.4% of visible light.

  • Useful Range : 425-675nm
  • Optical Density : 1.2
  • Transmission: 6.25%
  • Tolerance : +/- 0.63%
  • Surface Quality : 40/20

 

ND Series – Visible (VIS) Spectrum

  • Absorptive filter effective from 425-675nm
  • Available in optical densities ranging from 0.10-6.0

Neutral Density Filters serves 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

 

ND120 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.
