MidOpt - ND400 Neutral Density (ND) Filter - Absorptive 0.01% Transmission
SKU: ND400-25.5
The MidOpt ND400 Neutral Density (ND) Filter has an optical density of 4.0, or average 0.01% transmission across the visible (VIS) spectrum. The ND400 has identical male and female threads on either end so it can be stacked with other ND filters to achieve various optical densities. Because the glass substrate is absorbing 99.9% of the light that passes into the filter, these filters are not recommended for use with lasers or immediately in front of higher wattage lighting. MidOpt ND Filters are double-side polished for exceptional parallelism and optical flatness.
