ND Filters are used to reduce transmission evenly over a range of wavelengths in a variety of applications including microscopy, imaging, or spectroscopy. ND Filters reduce the intensity of light by absorbing or reflecting an even portion of the transmitted light determined by the filter's optical density. ND Filters are available in a wide range of densities or materials that may be stacked together to increase optical density.
