ND300-25.4 | ND300 Neutral Density Filter - Absorptive 0.1% Transmission

The MidOpt ND300-25.4 is an absorptive neutral-density filter with an optical density of 3.0, meaning it transmits an average of 0.1% of visible light. 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. Because the glass substrate absorbs 99.9% of the light that passes through the filter, these filters are not recommended for use with lasers or immediately in front of higher-wattage lighting. All MidOpt filters can also be purchased unmounted and in custom dimensions upon request from Machine Vision Direct.
