Neutral Density (ND) Filter - Absorptive 12.5% Transmission, 425-675nm - MidOpt ND090 Size:25.5mm The substrate material is Borofloat®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
