MidOpt Ni200 Neutral Density Filter Reflective 1% Transmission

Optical Filters & Kits
Midwest Optical : Ni200
Description
The Midwest Optical Ni200 Neutral density filters can be used to reduce the amount of light reaching the camera to about average 1% transmission, thus allowing longer exposure times that result in reduced depth of field. This improves the separation of subject matter from the foreground and/or background. 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.
Features
- Available in a variety of optical densities
- Reduce light intensity while maintaining a wide aperture and shallow depth of field. Every 0.3 density increment equals one f-stop
- Minimize pixel saturation
- Can be stacked with other Neutral Density Filters to test various optical densities
- Exceptional surface quality; 40/20 scratch/dig
Specifications
- Useful Range : 400-2000nm
- Optical Density : 2.0
- Average Transmission: 1%
- Tolerance : +/- .5
- Surface Quality : 40/20
