Neutral Density FiltersFilters
Ni Series – VIS/SWIR
MidOpt 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.
Overview
Neutral Density Filters-VIS/NIR
MidOpt 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. 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
Ni Series – Broad Spectrum; VIS/NIR
- ◆Low reflectivity filter effective from 400-2000nm
- ◆Available in optical densities ranging from 0.3-2.0
- ◆Coated on low-expansion, heat-resistant Borofloat® glass
