Neutral Density (ND) filters are designed to reduce transmission evenly across a portion of a specific spectrum. They are typically defined by their Optical Density (OD) which describes the amount of energy blocked by the filter. A high optical density value indicates very low transmission, and low optical density indicates high transmission. ND filters can be stacked to achieve a custom optical density. To calculate the final system OD, simply add the OD of each filter together.We can customize alternative size, material, coating and other paramenter you want. Welcome your inquiry to us!
