MidOpt - ND090 Neutral Density (ND) Filter - Absorptive 12.5% Transmission
SKU: ND090-25.5
The MidOpt ND090 Neutral Density (ND) Filter has an optical density of 0.9, or average 12.5% transmission across the visible (VIS) spectrum. The ND090 has identical male and female threads on either end so it can be stacked with other ND filters to achieve various optical densities. For example, two ND090 filters stacked together would perform approximately the same as one ND180 Filter. MidOpt ND Filters are double-side polished for exceptional parallelism and optical flatness.
