ND120-37 | ND120 Neutral Density Filter - Absorptive 6.25% Transmission
Part: ND120-37
Diameter: M37 x P0.75
The MidOpt ND120-37 is an absorptive neutral-density filter with an optical density of 1.2, averaging 6.25% transmission across the visible spectrum. These filters have identical male and female threads on both ends, allowing them to be stacked with other ND filters to achieve various optical densities. For example, the result of stacking two ND120 filters would be very similar to using one (ND240) filter. The visible transmission would be approximately 0.4% of visible light. All MidOpt filters can also be purchased unmounted and in custom dimensions upon request from Machine Vision Direct.
