The MidOpt ND030-72 is an absorptive neutral-density filter with an optical density of 0.3, or an average 50% 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, two ND030 filters stacked together would perform approximately the same as one ND060 filter. All MidOpt filters can also be purchased unmounted and in custom dimensions upon request from Machine Vision Direct.
