Neutral Density Filters, Visible and SWIR Wavelengths

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

• 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
