Optical Photometer Custom Optical Filters Neutral Tunable Optical Bandpass Filter
|
...Filter with Optical Density of 0.1 to 4.0 A neutral-density filter, or ND filter, is a filter that reduces or modifies the intensity of all wavelengths, or colors, of light equally, giving no changes in hue of color rendition. The purpose of a standard photographic neutral-density filter is to reduce the amount of light entering the lens. Doing so allows the photographer to select combinations of aperture......
