VIS Neutral Density Filters (NDFs), operating within the 400-700nm visible light spectrum, are precision optical components designed to attenuate light intensity uniformly across the entire visible spectrum without altering its spectral composition. These filters are engineered to provide a neutral response, meaning they reduce the brightness of all colors equally, preserving the true color balance and contrast of the original scene or image.
